The 2025 Pacific hurricane was an above-average season, and the most active season on record for the Eastern Pacific basin, surpassing the 1992 season in terms of number of named storms. It featured a total of 29 named storms across the Central and Eastern basins, with 13 hurricanes and 9 major hurricanes. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; both ended on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. Tropical cyclogenesis is possible at any point during the year, however, as demonstrated by Tropical Depression One-C which developed on March 14, and Hurricane Bruna, which formed on November 30 and dissipated on December 3.
The strongest storm of the season, Hurricane Zelda, formed in mid-October and reached category 5 strength, the first since Hurricane Todd two years prior. The most impactful storm of the season, Tropical Storm Flossie, formed in July east of 90°W and brought severe flooding to parts of Central America along with Tropical Depression Two in the Atlantic basin. Flossie was the wettest tropical cyclone recorded in Costa Rica and also one of the deadliest Pacific tropical cyclones since reliable records began. Several storms also formed in the Central Pacific basin this year, marking the first season since 2018 to feature more than one named storm to form in the Central Pacific basin. Three storms also crossed the International Date Line this season; Hurricanes Juliette and Lala, as well as Tropical Storm Octave, which went on to become a category 5- equivalent typhoon.

Forecasts include weekly and monthly changes in important factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to the National Oceanic and Atmospheric Administration (NOAA), the average hurricane season in the Eastern and Central Pacific between 1991 and 2020 contained approximately 15 tropical storms, 8 hurricanes, and 4 major hurricanes. NOAA generally classifies a season as above average, average, or below average based on the cumulative ACE index, but occasionally the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is also considered.
On May 20, 2025, the Servicio Meteorológico Nacional (SMN) issued its forecast for the season, predicting a total of 21 named storms, 11 hurricanes, and 6 major hurricanes to develop. On May 30, 2025, the National Oceanic and Atmospheric Administration (NOAA) issued their outlook, calling for an above-average season with 16–20 named storms, 8–12 hurricanes, and 4-6 major hurricanes. The reason for their outlook was the forecast of an El Niño to continue through the season, which reduces vertical wind shear across the basin and increases sea surface temperatures, favoring increased tropical cyclone activity.
Season timeline[]
Systems[]
Tropical Depression One-C[]
| Tropical depression (SSHWS) | |
  | |
| Duration | March 14 – March 16 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1004 mbar (hPa) |
On March 13, an area of low pressure developed within the Intertropical Convergence Zone (ICZ), several miles west of Palmira and Kingman Islands. The low drifted westward and rapidly developed, with the CPHC upgrading the system into Tropical Depression One-C the next day. This marked the earliest formation of a tropical cyclone in the Central Pacific basin since Hurricane Pali in 2016. One-C immediately began to feel impacts from surrounding dry air and moderate wind shear, which limited any more development as the depression drifted slowly west and north. On March 16, most associated deep convection had waned, and One-C was declared a remnant low. The remnant turned west southwestward and was absorbed into the ICZ about a day later.
One-C never impacted land during its duration.
Hurricane Alvin[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | May 22 – May 28 |
|---|---|
| Peak intensity | 125 mph (205 km/h) (1-min) 950 mbar (hPa) |
On May 20, an area of low pressure spawned within a cluster of showers and thunderstorms located over the eastern Pacific, several hundred miles south of Mexico. The low quickly became better organized as it moved slowly westward, and on May 22, it was upgraded into Tropical Depression One-E. The depression continued slowly westward and intensified into Tropical Storm Alvin the next morning. Alvin turned northwestward while intensifying amid favorable conditions and gained hurricane status on May 24. Alvin continued to intensify while maintaining its slow motion to the northwest, and the next morning, it attained major hurricane status. Alvin reached its peak intensity with winds of 125 mph and a central pressure of 950 millibars later on May 25. Increasing wind shear on May 26 caused Alvin to begin weakening, with the hurricane falling below major hurricane status later that day. Continued wind shear of over 25 knots (30 mph) caused Alvin to quickly weaken as it turned sharply northeastward late on May 26. Alvin fell below hurricane status on May 27, with wind shear continuing to plague the storm. Alvin weakened into a tropical depression on May 28, and it further degenerated into a remnant low six hours later. The remnant turned eastward and approached the Mexican coastline before dissipating the next morning.
Alvin never severely impacted land during its lifetime, though rip currents and rough seas generated by the hurricane were reported along the Mexican coast. Some stormy weather was reported in Mexico as Alvin's remnants made their closest approach. No damages or fatalities were reported.
Tropical Storm Barbara[]
| Tropical storm (SSHWS) | |
  | |
| Duration | May 26 – May 28 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 1002 mbar (hPa) |
On May 21, a tropical wave interacted with a disturbed area of weather located to the west of the disturbance that would later become Hurricane Alvin. This spawned a new tropical low that began to move westward and away from land. The low slowly became better organized amid unusually favorable conditions, and on May 26, it was upgraded into Tropical Depression Two-E. The depression continued to intensify and was upgraded into Tropical Storm Barbara twelve hours later, just before crossing 140°W. Barbara then crossed into the Central Pacific basin and reached its peak intensity with winds of 45 mph and a central pressure of 1002 millibars on May 27. After peaking, Barbara moved into a less favorable environment consisting of very dry air and moderate wind shear. The storm began to weaken and became devoid of deep convection early on May 28, prompting the NHC to downgrade it into a remnant low. The remnant continued westward before opening up into a trough several hours later.
Barbara never impacted land during its lifetime.
Tropical Storm Cosme[]
| Tropical storm (SSHWS) | |
  | |
| Duration | June 3 – June 5 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 1001 mbar (hPa) |
On June 1, an area of low pressure spawned within a broad span of disturbed weather located far to the south of Baja California. The low became better organized over the following days as it moved northwestward, and on June 3, it was upgraded into Tropical Depression Three-E. The depression intensified quickly and was upgraded into Tropical Storm Cosme the next morning. Cosme continued to intensify while remaining on a steady track to the northwest, and it reached its peak intensity with winds of 50 mph and a central pressure of 1001 millibars on June 4. Increasing wind shear, dry air, and decreasing sea surface temperatures resulted in a rapid demise on June 5, and Cosme degenerated into a remnant low later that day. The remnant turned northeastward as it was steered by a larger low to its north. The next day, Cosme's remnant dissipated as it was absorbed into the other low.
Cosme never impacted land during its lifetime.
Tropical Storm Dalila[]
| Tropical storm (SSHWS) | |
  | |
| Duration | June 13 – June 16 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 1001 mbar (hPa) |
On June 11, a broad area of disturbed weather located offshore of Baja California Sur spawned a low-pressure system. The low drifted southwestward while slowly organizing amid favorable conditions, and on June 13, it was upgraded into Tropical Depression Four-E. The depression turned westward under weak steering influences and remained somewhat disorganized for the next 24 hours. The next day, it began to increase in organization and was upgraded into Tropical Storm Dalila. The storm continued slowly westward and intensified at a quicker rate, reaching its peak intensity with winds of 50 mph and a central pressure of 1001 millibars on June 15. Dalila moved away from Baja California Sur and into a less favorable environment consisting of cooler sea surface temperatures and drier air, resulting in weakening. On June 16, Dalila fell below tropical storm status, and further degenerated into a remnant low a few hours later. The remnant continued westward until dissipating over the open ocean several hours later.
Impacts in Mexico and Baja California Sur were minimal, with only some damages from rough seas, gusty winds, and rainfall reported.
Hurricane Erick[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | July 4 – July 9 |
|---|---|
| Peak intensity | 90 mph (150 km/h) (1-min) 979 mbar (hPa) |
On June 23, a tropical wave exited the west coast of Africa. The wave tracked westward across the tropical Atlantic and entered the Caribbean Sea on June 28. The wave remained poorly organized as it crossed the Caribbean and moved over Central America on July 1. After entering the Pacific, the wave developed a low-pressure circulation and began to organize. On July 4, it was upgraded into Tropical Depression Five-E as it continued westward. The depression turned west northwestward and intensified into Tropical Storm Erick the next morning. Erick continued to intensify amid favorable conditions and attained hurricane status on July 6. Continued intensification occurred, and Erick reached a peak intensity with winds of 90 mph and a central pressure of 979 millibars- a high end category 1 hurricane. After peaking, Erick retained its intensity for several hours before encountering decreasing sea surface temperatures and drier air. This resulted in steady weakening, and Erick fell below hurricane status on July 8. Erick continued to spin down as convection waned, and early on July 9, Erick was declared post-tropical as it was devoid of upper-level convection. The remnant continued to spin down as it moved north westward, until ultimately dissipating on July 10 over the open ocean.
Erick never impacted land during its lifetime, though its precursor wave brought stormy weather to parts of Central America.
Hurricane Iona[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | July 7 – July 12 |
|---|---|
| Peak intensity | 130 mph (215 km/h) (1-min) 950 mbar (hPa) |
On July 5, an area of low pressure spawned within a disturbance associated with the Intertropical Convergence Zone, far to the south of Hawaii. The low drifted slowly westward and became increasingly better organized amid favorable conditions, and on July 7, it was upgraded into Tropical Depression Two-C. The depression continued slowly westward before curving northward through a break in the subtropical ridge on July 8. Intensification began on July 8, and Two-C strengthened into Tropical Storm Iona later that day. Iona continued generally northward and began to quickly intensify on July 9. Later that day, Iona attained hurricane status and began to rapidly intensify. Iona was upgraded into a major hurricane early on July 10, and continued to intensify until it reached its peak intensity as a minimal category 4 hurricane with winds of 130 mph and a central pressure of 950 millibars. This made Iona the most intense hurricane in the Central Pacific basin since Hurricane Walaka seven years earlier. Iona retained its intensity for 12 hours before an eyewall replacement cycle, paired with increasing wind shear, resulted in rapid weakening. The hurricane fell below major hurricane status on July 11, and further below hurricane status later that same day. Iona continued to weaken as it moved northward, and on July 12, it degenerated into a remnant low after losing nearly all associated convection. The remnant circulation continued northward and approached the Northwestern Hawaiian Islands before turning sharply west-northwest and dissipating on July 14.
Iona's remnant brought minor impacts to the Northwestern Hawaiian Islands, with squally weather reported as it passed through. No damages or fatalities were reported.
Tropical Storm Flossie[]
| Tropical storm (SSHWS) | |
  | |
| Duration | July 22 – July 24 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 1000 mbar (hPa) |
On July 5, a tropical wave moved off the west coast of Africa. Over the next two weeks, the wave crossed the tropical Atlantic and Caribbean Sea before splitting into two halves. The northern half reached the Yucatan Peninsula on July 18, while the other half moved into the Pacific Ocean after crossing Central America on July 20. The half that moved into the Pacific began to organize off the coast of Nicaragua on July 21, and it was upgraded into Tropical Depression Six-E the next morning. At the time, the depression was located east of 90°W, making it one of the easternmost forming tropical cyclones in the East Pacific basin. Six-E turned northwestward and intensified into Tropical Storm Flossie later that day. Flossie continued to intensify as it moved parallel to the Central American coast, and it attained a peak intensity with winds of 50 mph and a central pressure of 1000 millibars on July 23. Flossie then absorbed the remnant of Tropical Depression Two from the Atlantic basin and curved northward. The storm made landfall near the border of El Salvador and Guatemala at peak intensity. Flossie quickly weakened, degenerating into a remnant low on July 24. The remnant persisted for a few more hours before dissipating over the mountainous terrain of Guatemala.
Flossie, along with Tropical Depression Two in the Atlantic, brought severe impacts due to rainfall to parts of Central America and Mexico. In Nicaragua and Honduras, rainfall totals of up to 12 inches (305 mm) in some areas caused significant flooding, landslides, and mudslides that caused widespread devastation. In El Salvador, rainfall totals from Flossie reached over 20 inches (508 mm), which along with storm surge, caused significant water damages across the small country. In Guatemala, rainfall reached totals of over 35 inches (889 mm) within a span of just three days. These rains caused severe damages that, when added together with Two in the Atlantic, totaled near $225 million, with 53 fatalities attributed to both storms in Mexico, Guatemala, Belize, and Honduras. Damages from Flossie alone totaled nearly another $200 million (USD), and there were 121 fatalities attributed to Flossie alone. This brought total damages from Flossie to $425 million (USD) and total direct fatalities to 174.
Hurricane Gil[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | July 24 – August 2 |
|---|---|
| Peak intensity | 130 mph (215 km/h) (1-min) 949 mbar (hPa) |
On July 22, an area of low pressure developed within a cluster of showers and thunderstorms located over the eastern Pacific, south of Baja California Sur. The low became increasingly better defined as it moved westward, and on July 24, it developed into Tropical Depression Seven-E. The depression began to moved west northwestward and intensified into Tropical Storm Gil 24 hours later. Gil continued generally west northwestward while steadily intensifying amid favorable conditions, and on July 27, it reached hurricane intensity. Gil continued to quickly intensify, and on July 28, it attained major hurricane status. Continued intensification occurred, and Gil attained its peak intensity as a minimal category 4 hurricane with winds of 130 mph and a central pressure of 949 millibars on the 28th. Slight weakening occurred shortly afterward due to an eyewall replacement cycle, and Gil fell to category 3 status six hours later. Later on July 28, Gil moved into an environment consisting of drier, more stable air, and began weakening more steadily. On July 29, Gill fell below major hurricane status as it continued on its west-northwest track toward the Central Pacific basin. Gil further weakened into a category 1 hurricane on July 29 before entering the Central Pacific basin. Gil fought off dry air entrainment on July 30 and strengthened slightly, reaching a secondary peak intensity with winds of 90 mph and a central pressure of 976 millibars. This intensification was short lived as wind shear began to increase later on July 30, and the hurricane began to weaken once again. On July 31, Gil fell below hurricane status and curved toward the west as it was steered by easterly flow. Gil fell below tropical storm status on August 2 as it approached the Big Island of Hawaii. Gil degenerated into a remnant low later that day as it made its closest approach to the Big Island, passing over the southernmost tip of the island late on August 2. The remnant continued west-northwest and westward before opening into a trough of low pressure on August 4.
Impacts in Hawaii from Gil were minimal, with stormy weather causing minor damages as it passed through. No fatalities were reported from the storm.
Hurricane Ivo[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | August 1 – August 8 |
|---|---|
| Peak intensity | 140 mph (220 km/h) (1-min) 946 mbar (hPa) |
On July 15, a tropical wave exited the west coast of Africa. The wave tracked westward across the tropical Atlantic, approaching South America on July 20. After moving inland over South America, the wave lost most associated thunderstorm activity. The wave continued across South America and emerged into the Pacific on July 26. Thunderstorm activity increased as it moved westward, and it developed an area of low pressure and began to organize on July 31. The next day, the low organized substantially and was upgraded into Tropical Depression Eight-E. The depression continued west and west northwestward as Tropical Storm Henriette formed over the eastern Pacific the next morning. Later on August 2, Eight-E intensified into Tropical Storm Ivo as it began to quickly intensify amid very favorable conditions. On August 3, Ivo intensified into a hurricane after developing a well-defined eye. Continued intensification occurred, and Ivo attained major hurricane status early on August 4. Ivo then rapidly intensified and attained a peak intensity with winds of 140 mph and a central pressure of 946 millibars later that day. After peaking, wind shear began to increase and weakening ensued early on August 5. Ivo fell below major hurricane status later that same day as it curved northwest along the periphery of the subtropical ridge that had been guiding it. The hurricane weakened at a slow rate on August 6, retaining its status as a category 2 hurricane through much of August 6 before decreasing sea surface temperatures induced faster weakening. Ivo fell below hurricane status on August 7 as it turned north northwestward and into deteriorating conditions in the Central Pacific basin. The storm quickly lost all upper-level convection and was declared post-tropical on August 8 as it curved northwestward. The remnant system continued its general northwestward track over the central Pacific Ocean before opening up into a trough on August 11.
Ivo never impacted land during its duration as a tropical cyclone.
Tropical Storm Henriette[]
| Tropical storm (SSHWS) | |
  | |
| Duration | August 2 – August 6 |
|---|---|
| Peak intensity | 65 mph (100 km/h) (1-min) 992 mbar (hPa) |
On July 31, a well-defined area of low pressure spawned within a broad cluster of showers and thunderstorms located south of Mexico. The low moved east southeastward and south under weak steering flow while quickly organizing. Gale-force winds were reported near the center of the low on August 1, though a defined center of circulation had not yet developed. The next morning, satellite imagery was able to locate a center of circulation, and it was upgraded into Tropical Storm Henriette after turned westward. Henriette moved steadily westward and curved northwestward on August 3 while intensifying amid generally favorable conditions. On August 4, the storm reached its peak intensity with winds of 65 mph and a central pressure of 992 millibars. Henriette retained this intensity despite forecasts calling for continued intensification to hurricane status. On August 5, Henriette approached mainland Mexico and began to weaken somewhat due to land interaction. The storm made landfall in the state of Jalisco with winds of 50 mph on August 5. Weakening ensued as Henriette moved inland and curved northeastward, falling below tropical storm strength later that day. On August 6, Henriette degenerated into a remnant low over central Mexico. The remnant continued northeast before dissipating later that day.
Heavy rainfall from Henriette impacted much of southern and central Mexico, with over 10 inches falling in the states of Jalisco, Nayarit, Zacatecas, and Durango. Other states including Colima, Michoacan, Guanajuato, and San Luis Potosi recorded rainfall totals of over 5 inches in some cities. This rainfall resulted in severe flooding, mudslides, and landslides that caused severe damages totaling over $100 million (USD) and 6 direct fatalities.
Hurricane Juliette[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | August 8 – August 22 (Exited basin) |
|---|---|
| Peak intensity | 130 mph (215 km/h) (1-min) 950 mbar (hPa) |
On August 6, showers and thunderstorms associated with the outer rainbands of Tropical Storm Henriette spawned a new area of low pressure south of Jalisco. The low meandered for the next 30 hours as it became increasingly better organized and developed a circulation. On August 8, the low began to move westward as ridging built over the Pacific and conditions became increasingly more favorable. The NHC upgraded the low into Tropical Depression Ten-E later that day after it developed a well-defined center of circulation. Very favorable conditions allowed the depression to intensify quickly, and it was upgraded into Tropical Storm Juliette six hours later. Juliette continued to quickly intensify and attained hurricane status just 24 hours later. Late on August 10, Juliette began to rapidly intensify, and it reached category 2 status. The next morning, the hurricane reached category 3 status, and Juliette subsequently attained its operational peak intensity with winds of 120 mph and a central pressure of 960 millibars. Juliette remained a major hurricane for eighteen hours before an eyewall replacement cycle, along with increasing wind shear, resulted in weakening. Juliette continued westward under the influence of a strong subtropical ridge and fell to category 1 status on August 12. The next morning, Juliette moved into a more favorable environment and re-intensified into a category 2 hurricane. Juliette remained a category 2 hurricane through August 13, attaining a secondary peak intensity with winds of 105 mph and a central pressure of 971 millibars. The hurricane weakened slightly as its eye became ill-defined on August 14, but this weakening was short lived. Juliette began to strengthen once again late on August 14 as it continued briskly westward, and it regained major hurricane status. Continued intensification occurred, and Juliette reached its peak intensity as a minimal category 4 hurricane with winds of 130 mph and a central pressure of 950 millibars on August 15. Juliette moved into an environment consisting of drier air and moderate wind shear late on August 15 as it approached the Central Pacific basin and began to weaken. The hurricane entered the Central Pacific basin later that day as a weakening category 2 hurricane; weakening continued as Juliette moved into the basin, and it fell to category 1 status on August 16. Juliette further fell below hurricane intensity later on August 16 as it continued westward. The storm passed about 150 miles south of Hawaii on August 18 as a minimal tropical storm. Intensification resumed on August 19 as wind shear relaxed somewhat, and Juliette reached its fourth peak intensity as a moderate tropical storm with winds of 60 mph and a central pressure of 997 millibars. The storm retained this intensity as it moved west northwestward, parallel to the Northwestern Hawaiian Islands. Juliette then crossed the International Dateline on August 22 and subsequently entered the West Pacific basin, with responsibilities shifting over to the JTWC and JMA. The JTWC and JMA immediately classified Juliette as a severe tropical storm with winds near 60 mph (10-min), and 65 mph (1-min). Juliette intensified amid modestly favorable conditions and reached its peak intensity in the West Pacific as a category 1-equivalent severe tropical storm with winds of 80 mph (1-min) and 70 mph (10-min) on August 23. The storm then turned northwestward along the edge of the subtropical ridge and into an unfavorable environment consisting of strong wind shear and drier air. Juliette weakened as it continued its northwest track, and it ultimately degenerated into a remnant low on August 26.
Juliette brought minor impacts to the Hawaiian Islands as it passed to the south between August 17 and 18. Rainfall and rough seas were reported during this time, causing minimal coastal damages.
Hurricane Kiko[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | August 15 – August 24 |
|---|---|
| Peak intensity | 155 mph (250 km/h) (1-min) 930 mbar (hPa) |
On August 2, a tropical wave exited the west coast of Africa. The wave tracked westward across the tropical Atlantic and Caribbean Sea during the next ten days with no development. After crossing Central America on August 13, the wave entered the Pacific Ocean and began to show signs of organization. The wave continued generally westward while organizing quickly, and on August 15, it was upgraded into Tropical Storm Kiko after satellite imagery indicated a well-defined circulation with estimated winds around 35 kts (40 mph). Kiko immediately began to rapidly intensify amid extremely favorable conditions, and it attained hurricane status on August 16, just eighteen hours after being named. Kiko continued to intensify as it turned west northwestward, and it attained category 2 status that same evening. The next morning, Kiko entered another phase of rapid intensification and attained category 4 status. Continued intensification occurred, and Kiko reached its peak intensity as a high-end category 4 hurricane with winds of 155 mph and a central pressure of 930 millibars late on August 17. Kiko took on annular characteristics during this time and levelled off in intensity, maintaining its status as a high-end category 4 hurricane through August 18. Late on the 18th, increasing wind shear and drier air began to affect the hurricane, and Kiko began weakening. The hurricane fell below category 4 status on August 19, and further to category 2 status later that same day. Kiko began to decelerate while weakening, and it curved northwestward on August 20. The hurricane fell to category 1 status, though it managed to fight off dry air entrainment and strengthen somewhat on August 21. Kiko briefly re-attained category 2 status on the 21st, subsequently reaching a secondary peak intensity with winds of 100 mph and a central pressure of 974 millibars. Kiko turned back toward the west-northwest and began weakening once again as sea surface temperatures beneath the hurricane began to drop. Kiko fell below hurricane status on August 22 as conditions continued to worsen, and convection began to wane. The shallowing system turned westward under the influence of easterly flow, and on August 24, it degenerated into a remnant low. The remnant curved northwestward around a weak ridge before opening up into a trough on August 26 over the open ocean.
Kiko never impacted land during its lifetime, though rough seas and rip currents generated by the powerful hurricane were reported along the Mexico and United States coastlines.
Hurricane Lorena[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | August 19 – August 24 |
|---|---|
| Peak intensity | 115 mph (185 km/h) (1-min) 962 mbar (hPa) |
On August 18, a broad area of convection spawned a low-pressure circulation, just offshore of southern Mexico. The low moved westward and quickly organized, with the NHC classifying it as Tropical Depression Twelve-E the next day. The depression moved northwestward and intensified into Tropical Storm Lorena just six hours later. Lorena continued its track parallel to the Mexico coast while intensifying amid favorable conditions, and on August 21, it reached hurricane status. Continued intensification occurred, and Lorena reached category 2 status the next morning as it passed northeast of Socorro Island. Lorena then attained its peak intensity as a minimal category 3 major hurricane with winds of 115 mph and a central pressure of 962 millibars later on August 22. The hurricane began to move over decreasing sea surface temperatures and fell below major hurricane status just six hours later. Continued weakening occurred on August 23 as Lorena moved into an unfavorable environment consisting of drier air and colder waters. Late on August 23, Lorena fell below hurricane status as convection began to rapidly wane. The storm curved west northwestward as it became increasingly shallow, and on August 24, it degenerated into a post-tropical cyclone. The remnant of Lorena continued to moved west northwestward before turned toward the west-southwest on August 25. The following day, the remnant opened up into a trough of low pressure over the open ocean.
Impacts from Lorena along the coastline of Mexico and in Socorro Island were minimal, with only minor damages sustained in Socorro Island as Lorena made its closest approach. There was 1 fatality in Mexico due to strong rip currents and rough seas generated by Lorena.
Hurricane Mario[]
| Category 2 hurricane (SSHWS) | |
  | |
| Duration | August 26 – September 2 |
|---|---|
| Peak intensity | 100 mph (155 km/h) (1-min) 975 mbar (hPa) |
On August 19, the remnant circulation of Tropical Storm Dexter entered the Pacific Ocean. The remnant interacted with another area of disturbed weather located south of Mexico on August 22, forming a new disturbance. The disturbance drifted westward and slowly became better organized, and on August 26, it was upgraded into Tropical Depression Thirteen-E. The depression moved slowly westward while slowly intensifying, curving northward under weak steering flow on August 27. Thirteen-E intensified into Tropical Storm Mario later on August 27 as it continued northward. Mario then curved back toward the west-northwest as a ridge built over the eastern Pacific. Though the storm passed through a similar area as Hurricane Kiko nearly two weeks prior, very favorable conditions allowed Mario to reach hurricane status on August 29. Mario began to move steadily west northwestward while intensifying, and it was able to attain category 2 status early on August 30. Mario subsequently reached its peak intensity with winds of 100 mph and a central pressure of 975 millibars. The hurricane moved into a more stable environment later on August 30 and began to weaken somewhat as its eye became ill-defined. Mario turned sharply northward on August 31 through a weakness in the subtropical ridge, and decreasing sea surface temperatures and increasing wind shear began to impact the hurricane. Late on August 31, Mario fell below hurricane status as it continued northward. The storm began to lose most of its upper-level convection as sea surface temperatures continued to drop, and on September 2, it degenerated into a remnant low. The remnant had turned sharply to the west-northwest under the influence of easterly flow and continued this motion until dissipating over the open ocean the following day.
Mario never impacted land during its lifetime, though rough seas and rip currents were reported in Socorro Island and Mexico.
Tropical Storm Keli[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 2 – September 5 |
|---|---|
| Peak intensity | 40 mph (65 km/h) (1-min) 1004 mbar (hPa) |
On August 30, a broad area of convection persisted over the Central Pacific basin, roughly 500 miles southeast of Hawaii. A low-pressure circulation spawned within the convection as it drifted west northwestward during the next few days. On September 2, after passing south of the Big Island of Hawaii, the low was upgraded into Tropical Depression Three-C after satellite imagery indicated a well-defined center of circulation. Three-C turned northwest and intensified into Tropical Storm Keli the next morning. Keli moved parallel to the main Hawaiian Islands through September 3 and 4 while remaining a weak tropical storm, though its pressure had continued to drop during this time. On September 4, Keli attained its peak intensity with winds of 40 mph and a central pressure of 1004 millibars. Conditions began to worsen over Keli on September 5 as wind shear increased drastically, and the storm fell to tropical depression status. Keli turned sharply westward as wind shear of over 35 kts (40 mph) blasted nearly all associated deep convection away from its center, and it degenerated into a remnant low late on September 5. The remnant persisted through the next day until dissipating over the central Pacific Ocean.
Keli brought stormy weather to the Hawaiian Islands during its duration, dropping over 9 inches (229 mm) of rainfall in Oahu. Damages from Keli totaled roughly $6.5 million (USD), and no fatalities were reported.
Tropical Storm Narda[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 2 – September 4 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 1000 mbar (hPa) |
On August 21, a tropical wave exited the west coast of Africa. The wave crossed the tropical Atlantic and split into two halves. The first half ultimately aided in the formation of Hurricane Fernand in the Atlantic basin, while the second half crossed the Caribbean Sea with no development. After passing over Nicaragua, the wave entered the Pacific Ocean and began showing signs of organization on August 31. The wave turned west-northwest and was upgraded into Tropical Depression Fourteen-E on September 2. Fourteen-E intensified and was upgraded into Tropical Storm Narda the next morning. Narda continued generally west northwestward and intensified as it approached the coast of Mexico. The storm reached its peak intensity with winds of 50 mph and a central pressure of 1000 millibars on September 3, just before making landfall in the state of Oaxaca. Narda quickly weakened after moving inland, and it degenerated into a remnant low the next morning.
Impacts from Narda in Mexico were minimal, with heavy rainfall and wind gusts up to 60 mph (95 km/h) causing minor damages in Oaxaca. Damages totaled roughly $15 million (USD), with 2 fatalities reported in Oaxaca.
Tropical Storm Octave[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 8 – September 19 (Exited basin) |
|---|---|
| Peak intensity | 70 mph (110 km/h) (1-min) 992 mbar (hPa) |
On September 6, a low-pressure disturbance spawned within the Intertropical Convergence Zone near the western edge of the East Pacific basin. The low drifted west and northward while slowly becoming better organized, and on September 8, it was upgraded into Tropical Depression Fifteen-E. The depression drifted slowly westward over the next day while organizing, and on September 9, it was upgraded into Tropical Storm Octave. Octave continued westward and began to increase its forward motion. Early on September 11, it attained its operational peak intensity with winds of 50 mph and a central pressure of 1000 millibars, just after entering the Central Pacific basin. Several hours after peaking, wind shear increased drastically, causing Octave to quickly weaken. The storm fell below tropical storm strength later on September 11, and further degenerated into a remnant low on September 12. The remnant persisted, producing limited convection as it continued west and west northwestward. Wind shear relaxed on September 14, and convection began to deepen once again. Later that night, the remnant was re-upgraded into a tropical depression. Octave continued steadily west northwestward and re-intensified into a tropical storm on September 15. After reaching storm status, wind shear of around 15 knots (20 mph) began impacting the storm once again, limiting significant intensification. Octave continued to slowly intensify despite the continued wind shear, and it attained winds of 70 mph and a central pressure of 992 millibars on September 19 as it approached the International Dateline. Octave retained this intensity until crossing the International Dateline on September 20 and subsequently moving into the West Pacific basin.
The JTWC and JMA immediately began issuing their own advisories on Octave as it entered the basin, and it was classified as a severe tropical storm with 10-minute sustained winds of 60 mph. Octave ultimately began to rapidly strengthen as it curved northwest and north, intensifying into a category-5 equivalent typhoon with winds of 160 mph (1-min) and a central pressure of 920 millibars. The JTWC and JMA both assessed Octave's peak intensity as a violent typhoon with winds of 125 mph (10-min). Octave eventually curved northeastward and transitioned into a powerful extratropical cyclone before later crossing the International Dateline once again on September 26. Octave's extratropical remnant eventually impacted Alaska, bringing destructive winds and rain that caused about $25 million (USD) in damages.
Tropical Storm Priscilla[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 10 – September 12 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 998 mbar (hPa) |
On September 9, a tropical disturbance located offshore of Jalisco developed a low-pressure circulation. The low moved northwestward and quickly became better organize. The following day, the low was upgraded into Tropical Depression Sixteen-E after satellite imagery found a closed center of circulation. Sixteen-E quickly intensified and was upgraded into Tropical Storm Priscilla the next morning. Priscilla curved slowly north and northeastward on September 11 while intensifying amid very favorable conditions. The storm attained its peak intensity with winds of 60 mph and a central pressure of 998 millibars late on September 11, just before making landfall in the state of Sinaloa. Priscilla quickly weakened after moving inland, and it degenerated into a remnant low the next day as it continued northeastward.
Priscilla brought minimal impacts to west-central Mexico. Heavy rainfall of over 7 inches (178 mm) was reported in Sinaloa and Durango, leading to minor damages. There were no reported fatalities from Priscilla.
Hurricane Raymond[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | September 10 – September 15 |
|---|---|
| Peak intensity | 145 mph (230 km/h) (1-min) 940 mbar (hPa) |
On August 29, a tropical wave exited the west coast of Africa. The wave tracked westward and was monitored for development as it traversed the tropical Atlantic. It entered the Caribbean Sea on September 3, where wind shear prevented any chances for development. After crossing the Caribbean, the wave passed over Costa Rica and entered the Pacific Ocean on September 7. The wave continued westward and began showing signs of organization on September 9. Early the next morning, it was upgraded into Tropical Depression Seventeen-E after satellite imagery indicated a closed center of circulation. Seventeen-E continued westward and intensified into Tropical Storm Raymond twelve hours later. Raymond curved slowly northward during the next 30 hours while intensifying, and on September 12, it attained hurricane status. Raymond then entered a period of rapid intensification and reached major hurricane status later that same day. That night, Raymond further intensified into a category 4 hurricane as organization continued drastically improving. On the morning of September 13, Raymond reached its peak intensity with winds of 145 mph and a central pressure of 940 millibars. After peaking, Raymond began interacting with the Mountainous terrain of Mexico, resulting in weakening. The hurricane fell below category 4 status that night as it continued northwestward. As Raymond neared the coast of Mexico, it weakened below major hurricane intensity, hours before making landfall in Guerrero with winds of 110 mph. Rapid weakening ensued as Raymond curved north and northeast over Mexico, and it degenerated into a remnant low on September 15.
Impacts from Raymond in Mexico were moderate, with heavy rainfall and storm surge of up to 8 feet (2.4 m) causing some severe damages in Gurrero. Rainfall totals up to 11.5 inches (292 mm) were reported in central Mexico, leading to some severe damages from mudslides and landslides. Damages from Raymond totaled around $62 million (USD), with 4 direct fatalities linked to the hurricane.
Tropical Storm Sonia[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 12 – September 16 |
|---|---|
| Peak intensity | 65 mph (100 km/h) (1-min) 996 mbar (hPa) |
A tropical disturbance that had persisted several hundred miles south of Baja California Sur for a few days spawned an area of low pressure on September 11. The low rapidly organized and began drifting westward, and on September 12, it was upgraded into Tropical Storm Sonia. Sonia continued west northwestward and intensified amid favorable conditions. The storm curved northwestward on September 14 as it reached its peak intensity with winds of 65 mph and a central pressure of 996 millibars. Sonia maintained an impressive appearance featuring well-defined outflow with deep centralized convection. Forecasts called for Sonia to attain hurricane intensity, though dry air entrainment prevented further intensification. On September 15, Sonia passed over decreasing sea surface temperatures and began quickly weakening. The next day, Sonia had lost all associated upper-level convection and was classified as a remnant low. The remnant continued north northwestward until ultimately dissipating on September 17, several hundred miles south of California.
Sonia never impacted land during its lifetime.
Hurricane Tico[]
| Category 2 hurricane (SSHWS) | |
  | |
| Duration | September 18 – September 26 |
|---|---|
| Peak intensity | 110 mph (175 km/h) (1-min) 967 mbar (hPa) |
On September 4, a tropical wave exited the west coast of Africa. The wave tracked westward across the Atlantic with little to no development. After crossing the Caribbean Sea, the wave passed over Central America on September 12 and entered the Pacific Ocean. The wave passed over cold upwelling left in the wake of Hurricane Raymond, preventing development in an otherwise favorable environment. Continuing westward, the wave began to organize on September 17 as sea surface temperatures increased, and the next day, it was upgraded into Tropical Depression Nineteen-E. The depression turned toward the west-northwest and intensified into Tropical Storm Tico twelve hours later. Tico continued to steadily intensify amid favorable conditions, and it reached hurricane intensity late on September 19. Continued favorable conditions allowed for further intensification, and on September 20, Tico attained category 2 status. Tico achieved a peak intensity just below major hurricane status with winds of 110 mph and a central pressure of 967 millibars early on September 21. After peaking, dry air and increasing wind shear began to weaken the hurricane slowly. Tico fell below category 2 status on September 22, about ten hours after crossing into the Central Pacific basin. Continued weakening occurred as Tico curved northwestward through a weakness in the subtropical ridge. Tico fell below hurricane status on September 24 while continuing its general track to the northwest. The storm passed several hundred miles north of Hawaii, where unusually warm waters allowed it to maintain deep convective activity despite strong wind shear and dry air. Tico still continued weakening, and it fell below storm strength late on September 25. Twenty-four hours later, Tico finally lost almost all associated deep convection as sea surface temperatures dropped below 26°C, and it degenerated into a remnant low. The shallow circulation continued northeastward, eventually dissipating far to the north of the western Hawaiian Islands on September 28.
Tico never impacted land during its lifetime, though rough seas and rip currents generated by the hurricane were reported in Hawaii.
Tropical Storm Velma[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 25 – September 29 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 1004 mbar (hPa) |
On September 22, a broad area of convection associated with the Intertropical Convergence Zone spawned a low-pressure system. The low drifted north and west over the next few days, and on September 25, it was upgraded into Tropical Depression Twenty-E. The depression moved northwestward and intensified, with it being upgraded into Tropical Storm Velma just six hours later. Velma continued its northwest track and slowly intensified, while dry air to its northwest limited significant development. On September 28, as Velma passed northeast of Socorro Island, it attained its peak intensity with winds of 50 mph and a central pressure of 1004 millibars. After reaching this intensity, decreasing sea surface temperatures, as well as dry air entrainment and wind shear, resulted in weakening. Velma quickly fell below storm strength on September 29, and further degenerated into a remnant low later that day. The remnant continued northwestward until dissipating on October 1, far to the south of California.
Impacts in Socorro Island from Velma were minimal, with stormy weather only causing minimal damages.
Tropical Storm Wallis[]
| Tropical storm (SSHWS) | |
  | |
| Duration | October 1 – October 4 |
|---|---|
| Peak intensity | 40 mph (65 km/h) (1-min) 1005 mbar (hPa) |
On September 16, a tropical wave exited the west coast of Africa. The wave tracked westward across the tropical Atlantic and Caribbean Sea during the next ten days with no development. After crossing Central America on September 27, the wave entered the Pacific Ocean. After two days, the wave began showing signs of organization, and on October 1, it was upgraded into Tropical Depression Twenty-One-E. The depression intensified as it moved westward and was upgraded into Tropical Storm Wallis the next morning. Wallis immediately began to interact with the newly developed Tropical Depression Twenty-Two-E to its southwest, and it turned west northwestward. The larger circulation of now Tropical Storm Xina hindered further development of Wallis as its convection began to merge with Xina's. On October 3, Wallis weakened into a tropical depression, and all models were showing the storm to be absorbed into Xina's circulation within the next 24-48 hours. On October 4, Wallis degenerated into a remnant low after almost all of its associated convection was absorbed into Xina. The remnant circulation subsequently was absorbed into Xina a few hours later.
Rainfall from the outer rainbands of Wallis brought minimal impacts to Mexico. No damages or fatalities were reported.
Tropical Storm Xina[]
| Tropical storm (SSHWS) | |
  | |
| Duration | October 1 – October 7 |
|---|---|
| Peak intensity | 65 mph (100 km/h) (1-min) 993 mbar (hPa) |
On September 30, an area of low pressure spawned within a large cluster of showers and thunderstorms far to the south of Baja California Sur. The low quickly developed a well-defined circulation as it moved slowly westward, and the next day, it was upgraded into Tropical Depression Twenty-Two-E. The depression immediately began a Fujiwara Interaction with Tropical Storm Wallis located to its northeast and turned sharply northward. It intensified into Tropical Storm Xina the next morning, while becoming almost stationary as its forward motion changed directions. Xina intensified quickly as it began moving eastward, and on October 3, it reached a peak intensity with winds of 65 mph and a central pressure of 993 millibars. The large storm eventually absorbed the smaller Wallis on October 4 and began to curve back toward the north. On October 5, Xina had curved northward, where increasing wind shear began to impact the storm. Weakening began later that day, and the storm turned northeastward ahead of an approaching trough. On October 7, Xina fell below storm strength as it approached the coast of Jalisco. Wind shear continued to increase, blasting most convection away from Xina's center of circulation. Later on October 7, Xina degenerated into a remnant low just offshore of Jalisco. The remnant continued northeastward, moving inland over Jalisco before dissipating the next morning.
Effects from Xina in Mexico were minimal, with only light rainfall reported as Xina approached from the southwest.
Tropical Storm York[]
| Tropical storm (SSHWS) | |
  | |
| Duration | October 15 – October 18 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 1002 mbar (hPa) |
On October 8, a tropical wave interacted with another disturbance located offshore of Panama. A new area of low pressure was spawned which began moving westward. Over the next week, the low continued westward with slow development. On October 15, organization improved, and the low was upgraded into Tropical Depression Twenty-Three-E. The depression continued to intensify and was upgraded into Tropical Storm York six hours later. York continued its westward track and reached a peak intensity of 45 mph winds and a central pressure of 1002 millibars on October 16. York retained this intensity for 18 hours before increasing wind shear began impacting the storm on October 17. York quickly weakened below storm status as convection was stripped away, and the next morning, it degenerated into a remnant low. The remnant continued westward before dissipating on October 19.
York never impacted land during its lifetime.
Hurricane Zelda[]
| Category 5 hurricane (SSHWS) | |
  | |
| Duration | October 18 – November 3 |
|---|---|
| Peak intensity | 165 mph (270 km/h) (1-min) 915 mbar (hPa) |
On October 6, a tropical wave exited the west coast of Africa. The wave tracked westward across the tropical Atlantic and moved over northern South America, eventually emerging over the Pacific Ocean on October 16. The wave quickly became better organized, and on October 18, it was upgraded into Tropical Depression Twenty-Four-E. The depression curved northwestward and intensified into Tropical Storm Zelda the next morning. Zelda quickly intensified and reached hurricane status the next morning, just 24 hours after being named. Zelda slowly intensified during the next day as it battled dry air entrainment but resumed a quicker intensification on October 21. Rapid intensification ensued on October 22, and Zelda quickly attained category 5 status. Zelda reached its peak intensity with winds of 165 mph and a central pressure of 915 millibars on October 22, making it the sixth-most intense Pacific hurricane on record, tied with Hurricanes Ava and Ioke. Zelda's eye became ill-defined that same night and weakening ensued. Zelda fell below category 5 status the next morning as it curved north northeastward. Later on October 23, organization improved and intensification began again. The next morning, Zelda was upgraded into a category 5 hurricane once again, reaching a secondary peak intensity with winds of 160 mph and a central pressure of 921 millibars. Weakening occurred again as Zelda crossed the 26°C isotherm, and dry air began to entrain itself into the hurricane's circulation. The hurricane curved westward on October 25 as a result of a building ridge while continuing to quickly weaken. Zelda fell below hurricane intensity later on October 25 and began to move to the west-southwest. Zelda further weakened below storm strength on October 27 as wind shear began to increase. Despite moving back over SST's of 26°C, Zelda retained its intensity as a tropical depression due to continued wind shear. On October 29, as Zelda began to turn back to the west, it degenerated into a remnant low. The remnant low turned northwestward and crossed into the Central Pacific basin on October 31, where unusually warm SST's of 25°C (77°F) allowed it to take on subtropical characteristics. Early on November 1, Zelda was classified as a subtropical storm around 30°N, far to the northeast of Hawaii. Zelda retained subtropical characteristics while intensifying amid modest conditions, and it attained a peak intensity with winds of 65 mph and a central pressure of 986 millibars on November 2. Zelda curved quickly northward and accelerated as it was boosted by the mid-latitude westerly flow. Decreasing SST's resulted in Zelda ultimately transitioning into a powerful extratropical cyclone over the north-central Pacific Ocean, several hundred miles south of Alaska. The extratropical cyclone intensified as it curved eastward, attaining hurricane-force winds on November 5. The cyclone turned east southeastward and accelerated across the north Pacific while slowly weakening, moving inland over Washington state on November 6.
Impacts from Zelda in Mexico were minor, with rainfall, rip currents, and rough seas causing minimal damages. In southwest Canada, Washington, and Oregon, Zelda brought moderate impacts as an extratropical cyclone. Heavy rainfall and gale-force winds caused widespread damages to structures across these areas. Remnants associated with Zelda also brought heavy rainfall and stormy weather across the western and central United States, causing minimal damages. Total loses from Zelda are estimated at $74 million (USD), with a total of 7 direct fatalities linked to the hurricane.
Hurricane Lala[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | October 21 – October 27 (Exited basin) |
|---|---|
| Peak intensity | 85 mph (140 km/h) (1-min) 981 mbar (hPa) |
On October 18, an area of low pressure spawned within a broad cluster of showers and thunderstorms associated with the Intertropical Convergence Zone in the Central Pacific near Tabuaeran. The low drifted very slowly northwestward during the next three days while organizing. On October 21, satellite imagery indicated a well-defined center of circulation, prompting the NHC to upgrade it into Tropical Depression Four-C. The depression turned westward and maintained a slow forward motion while gradually intensifying, and 24 hours later, it was upgraded into Tropical Storm Lala, the third system to be named in the Central Pacific basin. Lala continued slowly westward during the next few days while gradually gaining strength. On October 25, Lala turned to the northwest once again and neared hurricane strength. The next day, continued intensification allowed Lala to achieve hurricane status, though light to moderate wind shear prevented the hurricane from rapidly intensifying. Lala continued to intensify upon its approach to the International Dateline, crossing over the boundary with winds of 85 mph and a central pressure of 981 millibars. Lala was immediately classified by the JTWC and JMA as a typhoon with 10-minute sustained winds of 75 mph. Lala ultimately began weakening as it moved through the eastern West Pacific basin, passing north of the Marshall Islands as a severe tropical storm. Lala eventually degenerated into a remnant low on November 4, far to the southwest of Japan. The remnant continued across the Pacific before dissipating a few days later.
Lala never impacted land during its lifetime, though rip currents were reported in several Pacific Islands, including Hawaii.
Tropical Storm Aiden[]
| Tropical storm (SSHWS) | |
  | |
| Duration | November 4 – November 6 |
|---|---|
| Peak intensity | 40 mph (65 km/h) (1-min) 1006 mbar (hPa) |
On October 18, a tropical wave exited the west coast of Africa. The wave tracked across the tropical Atlantic and Caribbean Sea with no development, passing over Central America on October 28. The wave continued westward while slowly becoming better organized. On November 4, organization improved, and satellite imagery was able to indicate a closed center of circulation, prompting its upgrade into Tropical Depression Twenty-Five-E. The depression curved slowly northwestward and intensified into Tropical Storm Aiden the next morning. Aiden subsequently peaked in intensity as a minimal tropical storm with winds of 40 mph and a central pressure of 1006 millibars on November 5. Dry air entrainment, as well as strong wind shear began to weaken Aiden on November 6, causing the storm to weaken into a tropical depression. Nearly all associated convection had been sheared away on November 6, resulting in Aiden's demise into a remnant low. The remnant turned northeastward, eventually dissipating on November 8, far to the south of California.
Aiden never impacted land during its lifetime.
Hurricane Bruna[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | November 30 – December 3 |
|---|---|
| Peak intensity | 80 mph (130 km/h) (1-min) 986 mbar (hPa) |
On November 28, an area of low pressure spawned within a cluster of showers and thunderstorms in the far eastern Pacific. The low drifted westward and became better organized, with the NHC upgrading it into Tropical Depression Twenty-Six-E on November 30, just hours before the official end of the season. Twenty-Six-E continued slowly westward while slowly strengthening into the next day, and later on December 1, it was upgraded into Tropical Storm Bruna. The storm entered a sudden phase of rapid intensification as an eye began to appear on satellite imagery. Just twelve hours after being named, Bruna was upgraded into a hurricane. Bruna intensified further on December 2, reaching its peak intensity with winds of 80 mph and a central pressure of 986 millibars. This made Bruna one of only three recorded East Pacific hurricanes recorded in the month of December- the others being Nina in 1957 and Winnie in 1983. After peaking, wind shear drastically increased, resulting in a quick weakening trend. Bruna quickly fell below hurricane strength on December 2, and further below storm strength on December 3, before ultimately degenerating into a remnant low that night. The remnant turned north and moved inland over Gurrero before dissipating over central Mexico on December 4.
Impacts from Bruna in Mexico were minor, with heavy rainfall and gale-force wind gusts only causing minimal damages. No damage estimates or fatalities are known.
Storm names[]
The following list of names was used for named storms that formed in the East Pacific in 2025. This was the same list used in the 2019 season. The names York and Zelda were used for the first time this year. Additionally, during this season, all 24 names on the main list were used, and usage of the new auxiliary list created after the 2020 season occurred for the first time this year; the names Aiden and Bruna were used for the first time this year.
