The 2024 Atlantic hurricane season was a highly active and destructive Atlantic hurricane season that became the third-costliest tropical cyclone season on record and is tied with the 2005 season for the second-most active Atlantic hurricane season with twenty-eight named storms forming, only behind the 2020 season. It is also the fourth season in which the designated 21-name list of storm names was exhausted and the first to use the auxiliary list of 21 given names, which was introduced after the 2020 season. The exceptional activity in 2024 was largely attributed to La Niña conditions.
Thirty-two tropical or subtropical cyclones formed in 2024, the most for a single Atlantic hurricane season. Twenty-eight named storms formed during the season, and a record-breaking seventeen hurricanes formed during the season, with eight further intensifying into major hurricanes, that is, a tropical cyclone which attains maximum sustained winds of at least 115 mph (185 km/h). This was, at one point, the highest on record before being surpassed by the 2029 season five years later. Two Category 5 hurricanes, Leslie and Tony, formed during the season, making it the first season to feature a Category 5 hurricane since 2019.
The season officially started on June 1 and officially ended on November 30, dates that historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the early formation of Subtropical Storm Alberto on May 19. This was the first season with a pre-season system since the 2021 season. The first hurricane, Hurricane Ernesto, made landfall in Florida on July 6. Ten days later, Hurricane Gordon formed and made landfall in Florida in late July as a Category 4 hurricane. Hurricanes Kirk and Leslie both formed in late August, with Kirk making landfall in Louisiana as a Category 4 hurricane and Leslie devastating the Bahamas and the southeastern United States in early September. Activity continued throughout September as Hurricane Oscar formed on September 12 and struck North Carolina directly as a Category 2 hurricane. On September 22, Hurricane Tony, the second Category 5 hurricane of the season, formed and became the second-strongest landfalling Atlantic hurricane on record when it made landfall in Louisiana at peak intensity on the first day of October.
The season's extreme activity resulted in the recently-introduced auxiliary list of twenty-one given names being used for the first time, first demonstrated with Hurricane Adria on October 10, which made landfall on the Yucatán Peninsula on October 12. On October 19, the erratic Hurricane Braylen formed north of Colombia, rapidly intensifying before hitting Nicaragua as a powerful Category 4 hurricane. It crossed over into the Pacific Ocean intact, eventually returning to the Atlantic basin on October 24 and making landfall in Louisiana as a Category 1 hurricane two days later. On November 7, Hurricane Emery formed in the subtropics and crossed into the Alboran Sea, merging with another extratropical system three days later to become a rare Mediterranean tropical-like cyclone. The season concluded with Hurricane Gemma's dissipation on December 17. Gemma was the only Category 2 Atlantic hurricane recorded in the month of December and therefore became the most intense December hurricane on record. Collectively, the storms of this season caused at least 4,584 deaths and about $291.637 billion in damage. This makes it the third-costliest tropical cyclone season on record, behind the 2017 season and later the 2029 season, as well as the deadliest since 1998.
Almost all forecasting organizations predicted above-average activity due to low to moderate wind shear, warm sea surface temperatures, and the probability of a neutral El Niño-Southern Oscillation or La Niña. Even so, activity well exceeded expectations, and each prediction underestimated the number of tropical cyclones that formed throughout the season. Prior to the season, the strong El Niño observed in 2023 rapidly dissipated and progressed into a powerful La Niña. Sea surface temperatures rose 1.19°C above the 1991-2020 average, likely due to the peak of the Atlantic multidecadal oscillation in 2024. Despite the record-breaking activity, moderate wind shear dominated the Main Development Region (MDR), preventing the season from being even more active.

National meteorological services and scientific organizations are responsible for issuing hurricane activity forecasts both before and during each hurricane season. These agencies and services include the Tropical Storm Risk (TSR) Consortium of the University College London, the National Oceanic and Atmospheric Administration (NOAA), the United Kingdom Met Office (UKMO), Coastal Carolina University (CCU), and other meteorological universities. The forecasts take into account weekly and monthly changes in significant factors that influence the number of tropical storms, hurricanes, and major hurricanes that occur in a given year. Between 1991 and 2020, an Atlantic hurricane season averaged 14 tropical storms, seven hurricanes, three major hurricanes, and an accumulated cyclone energy (ACE) index of 72 to 111 units. ACE is a measure of the power of a tropical or subtropical storm calculated by adding the square of a tropical cyclone's maximum sustained winds at six-hour intervals. It is only calculated for full advisories on specific tropical and subtropical systems with wind speeds of 39 mph (63 km/h) or higher. The cumulative ACE index is used by NOAA to classify a season as above-average, average, or below-average, but the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is also taken into consideration.
Pre-season outlooks[]
The first forecast for the 2029 season was released by TSR on December 16, 2023. They anticipated a slightly above-average season with 15 named storms, 8 hurricanes, and 3 major hurricanes. On April 10, 2024, CSU released its forecast, also predicting a slightly above-average season with 15 named storms, 7 hurricanes, and 3 major hurricanes. Two days later, TSR released its second forecast, which predicted 17 named storms, 8 hurricanes, and 4 major hurricanes and an ACE index of 140 units. The organization based this on the prediction of warmer than normal sea surface temperatures and the anticipation of a neutral El Niño–Southern Oscillation or even a La Niña. On April 16, North Carolina State University released its predictions, forecasting a well above-average hurricane season with 16–20 named storms, 8–12 hurricanes, and 3–5 major hurricanes. The next day, The Weather Company (TWC) released their forecasts, also predicting 2024 to be a potentially hyperactive season with a total of 19 named storms, 10 hurricanes, and 4 major hurricanes.
On May 10, the NOAA issued their forecast calling for a 70% chance of an above-normal season with 16–19 named storms, 9–12 hurricanes, and 4–6 major hurricanes. They cited the expectation of a La Niña throughout the season and warm sea surface temperatures as factors that would fuel a potentially hyperactive season. TSR increased their predictions on May 11, this time predicting 19 named storms, 8 hurricanes, and 4 major hurricanes while also anticipating favorable conditions throughout the season. On May 14, the day before the "unofficial" start of the hurricane season, the UK Met Office released their predictions, anticipating an above-average season, with 17 named storms, 7 hurricanes, and 3 major hurricanes.
Mid-season outlooks[]
On June 1, at the start of the season, CSU released their second prediction for the season, which increased the number of named storms to 19, the number of hurricanes to 8, and the number of major hurricanes to 4. On July 2, the TSR revised their predictions to 20 named storms, 10 hurricanes, and 4 major hurricanes. One day later, the CSU revised their predictions a third time, increasing the number of named storms and hurricanes by one. On August 6, the TSR updated their forecast to 23 named storms, eleven hurricanes, and five hurricanes. They cited the low trade winds and the possibility of record-breaking sea surface temperatures across the entire North Atlantic Ocean as factors contributing to extreme activity. Finally, NOAA released their second and final forecast for the season that same day, predicting an extremely active season with 22–27 named storms, 9–13 hurricanes, and 4–7 major hurricanes, their most active prediction for an Atlantic hurricane season. They stated that the season had enough potential to become as active, if not more active, than 2020 or 2005.
Seasonal summary[]
The 2024 Atlantic hurricane season officially began on June 1, 2024. One of the busiest seasons on record, it produced a record thirty-two tropical depressions, surpassing the previous record of 31 set by the 2005 and 2020 seasons. Twenty-eight tropical or subtropical storms formed throughout the season, tying 2005 for the second-most number in a single hurricane season. Of these, a record-breaking seventeen intensified into hurricanes, the highest number ever observed. Eight of the hurricanes intensified into major hurricanes, surpassing the 2005 and 2020 seasons for the most in a single season. Two Category 5 hurricanes, Leslie and Tony, formed during the season, both of which became the first Category 5 hurricanes since Hurricane Lorenzo in 2019.
Many factors contributed to the season's well-above-average activity. A neutral El Niño-Southern Oscillation rapidly developed into a La Niña by July 2024, resulting in all-around favorable conditions conducive to tropical cyclone development across the Atlantic Ocean. Sea surface temperatures reached record levels across the basin, reaching 1.19 °C above the 1981–2010 average. This, along with a negative North Atlantic Oscillation, resulted in weaker trade winds, lower sea level pressures, and lower wind shear, causing record-breaking activity across the entire basin.
This season was also one of the most disastrous on record, featuring a pattern that was conducive to intense landfalls. All but five tropical cyclones directly affected land. Five hurricanes: Gordon, Kirk, Leslie, Tony, and Braylen, all made landfalls at Category 4 intensity or higher, three of which made landfall in Louisiana at such intensity. The season was exceptionally active for the Caribbean Sea, as twelve tropical cyclones passed through the area. The Gulf of Mexico also saw above-average activity, with four major hurricanes entering the basin. The season was reflected with an accumulated cyclone energy (ACE) index of 182 units, the highest value since 2017.
Pre- or early- season activity[]
Subtropical Storm Alberto developed on May 19, becoming the first pre-season storm in the Atlantic since 2021. Tropical storms Beryl, Chris, and Debby formed in the month of June, albeit as weak and short-lived storms. July featured above-average activity, with hurricanes Ernesto, Francine, Gordon, and Tropical Depression Eight forming. Ernesto became the first hurricane of the season and made landfall in Florida on July 6. Francine, the first major hurricane of the season, formed on July 11 and struck North Carolina as a weakening storm, closely followed by Hurricane Gordon, which devastated Cuba and Florida at major hurricane intensity. Gordon also broke a formation record for the earliest seventh-named storm in the Atlantic basin.
August continued this rate of activity with the formation of Helene, Ten, Isaac, Kirk, Joyce, and Leslie. Hurricane Helene formed on August 2, making landfall in Belize two days later, while Tropical Depression Ten formed in a similar area on August 10. A week later, Tropical Storm Isaac formed from a low-pressure area close to Bermuda. August 22 saw the formation of two hurricanes: Kirk and Joyce, the former making landfall in Cameron, Louisiana, as a Category 4 hurricane while the latter largely remained at sea. On August 29, Hurricane Leslie, the first Category 5 hurricane of the season, formed, causing widespread destruction throughout the Bahamas, Florida, Mississippi, and Louisiana.
Peak-season activity[]
September featured extreme activity with the formation of nine tropical cyclones: Tropical Depression Sixteen; tropical storms Patty, Rafael, and Valerie; and hurricanes Milton, Nadine, Oscar, Sara, and Tony. Milton was a strong Category 4 hurricane that remained far from land despite bringing showers and thunderstorms when it came close to Bermuda and the Azores. Tropical Depression Sixteen formed in the Gulf of Mexico on September 7 and was absorbed by Hurricane Leslie a day later as it made landfall in Louisiana on September 8. Hurricane Nadine formed on September 8 and made landfall on the Yucatán Peninsula as a Category 1 hurricane. Oscar formed on September 12 and struck North Carolina as a Category 2 hurricane. This was followed by the formation of Tropical Storms Patty and Rafael on September 16 and 19, respectively, the latter remaining far from land while Rafael made landfall in Texas as a tropical storm.
Hurricane Sara formed in the northeastern Atlantic on September 20, with its extratropical remnants affecting the United Kingdom as a powerful European windstorm. On September 22, Hurricane Tony, the second Category 5 Atlantic hurricane of the season, formed, becoming the third major hurricane to make landfall in Louisiana during the season. It became the costliest tropical cyclone on record, inflicting $175 billion in damages. Finally, Tropical Storm Valerie formed in the southwestern Caribbean Sea, making landfall in Central America before dissipating.
2024's extreme activity continued throughout October. Hurricane William formed on October 5, making landfall in Newfoundland as a Category 1 hurricane. William had one of the highest latitudes for a tropical cyclone at hurricane intensity on record. Tropical Depression Twenty-Five formed in the eastern Caribbean on October 10, and two days later, Hurricane Adria formed, the first known tropical cyclone to be named under the auxiliary naming list. It made landfall in the Yucatán Peninsula as it followed a similar path to Hurricane Helene months prior. On October 19, the erratic Hurricane Braylen formed north of Colombia, striking Nicaragua as a powerful Category 4 hurricane before crossing into the Eastern Pacific basin on October 22, only to return to the Atlantic basin on October 24 and make landfall in Louisiana two days later. As this was occurring, Tropical Storm Caridad formed off the East Coast of the United States.
Late-season activity[]
Activity slowed down during November and December. Tropical Storm Deshawn formed on October 31 and brought showers and thunderstorms over the Caribbean as a minimal tropical storm. On November 7, Hurricane Emery formed in the subtropics and crossed into the Alboran Sea before it turned extratropical, the only known Atlantic tropical cyclone to do so. Tropical Storm Foster formed a week after Emery's dissipation and remained off the coast. After the season concluded on November 30, Hurricane Gemma, the final storm of the season, formed as a subtropical cyclone near Bermuda nearly two weeks later, before going on to become the most intense Atlantic hurricane recorded in the month of December and the only Category 2 hurricane to form during December.
Systems[]
Subtropical Storm Alberto[]
| Subtropical storm (SSHWS) | |
  | |
| Duration | May 19 – May 21 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 1001 mbar (hPa) |
An extratropical cyclone formed southwest of Bermuda on May 17. Tracking northeastward, the low acquired subtropical characteristics gradually as it entered warmer waters and a more favorable environment. The storm strengthened into Subtropical Storm Alberto at 12:00 UTC on May 19. The storm tracked eastward as it reached a peak intensity of 60 mph (95 km/h), before weakening due to an interaction with a cold front system and encountering dry air and wind shear. By May 21, the deteriorating storm had merged with the cold front about 110 mi (180 km) northeast of Bermuda. Damages from the storm were minimal, though the subtropical storm brought showers and thunderstorms to Bermuda as it traveled around the island.
Tropical Storm Beryl[]
| Tropical storm (SSHWS) | |
  | |
| Duration | June 11 – June 13 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 1001 mbar (hPa) |
Late on June 10, an elongated area of low pressure developed about 430 miles (690 km) east of Georgia. A burst of convection near the center occurred six hours later and the system was designated Tropical Depression Two by the National Hurricane Center (NHC) in anticipation of further development. Mid-level dry air initially allowed only minimal development of the storm as it moved northwestward; however, the storm was able to develop stronger convection near its center, allowing it to strengthen into Tropical Storm Beryl at 18:00 UTC on June 11. Around this time, Beryl turned to the northeast due to the presence of a mid-level ridge over the United States. It reached a peak intensity of 45 mph (75 km/h) and a minimum pressure of 1001 mbar (29.56 inHg) just east of North Carolina. Afterwards, the storm gradually weakened as it exited the Gulf Stream and transitioned into an extratropical cyclone with tropical-depression force winds about 120 mi (195 km) south of Massachusetts on June 13 at 02:00 UTC. The low continued northeast before dissipating twelve hours later.
Tropical Storm Beryl caused minimal damage as it passed close by North Carolina and resulted in one person drowning from a rip current produced by the cyclone.
Tropical Storm Chris[]
| Tropical storm (SSHWS) | |
  | |
| Duration | June 24 – June 26 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 996 mbar (hPa) |
A tropical wave emerged into the Atlantic from the west coast of Africa on June 14. Moving westward, the wave exhibited sporadic convection, and as it entered the Caribbean Sea on June 19, the wave split up, with the northern portion heading northwestwards towards the Greater Antilles and the Bahamas, and the southern portion continuing westward in the Caribbean Sea. By June 22, the tropical wave had spawned a low-pressure system that headed northwestward towards the Yucatán Peninsula. On June 24 at 06:00 UTC, after emerging from the Yucatán Peninsula, the system developed a stronger circulation and resulted in the formation of a tropical depression. The next day, the system strengthened into Tropical Storm Chris. The storm gradually intensified until it reached its peak winds of 60 mph (95 km/h) at 18:00 UTC that day. Six hours later, the system made landfall near Tampico, Mexico, and subsequently weakened rapidly due to Mexico's mountainous terrain and degenerated into a remnant low no more than twelve hours after making landfall. The remains of Chris dissipated over Guanajuato by the later hours of June 26.
The precursor of Chris dropped precipitation of up to 4.76 in (121 mm) over Central America and southeastern Mexico. After Chris became a tropical cyclone, it brought torrential rainfall throughout southern Mexico as well as flash floods and minor storm surge along the states of Veracruz and Tamaulipas. Overall, Chris dealt roughly $5 million in damages.
Tropical Storm Debby[]
| Tropical storm (SSHWS) | |
  | |
| Duration | June 29 – July 2 |
|---|---|
| Peak intensity | 65 mph (100 km/h) (1-min) 988 mbar (hPa) |
A tropical wave emerged off the western coast of Africa in late June, organizing into a tropical depression at 06:00 UTC on June 29 south of Cape Verde. Eighteen hours later, the system intensified into Tropical Storm Debby. The large system turned northwest, strengthening under generally favorable conditions, and reached peak winds of 65 mph (95 km/h) and a fairly low pressure of 988 mbar (29.18 inHg) around 18:00 UTC on June 30. Debby plateaued in intensity for almost a day before weakening significantly as it faced increasingly hostile wind shear. Debby then weakened to a tropical depression at 06:00 UTC on July 2, before degenerating into a tropical wave just six hours later. The remnants of Debby continued westward before dissipating the day after.
Hurricane Ernesto[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | July 3 – July 7 |
|---|---|
| Peak intensity | 80 mph (130 km/h) (1-min) 983 mbar (hPa) |
A broad low-pressure area formed just east of Honduras on July 2. Moving northwest, the system's convection increased gradually, resulting in the formation of Tropical Storm Ernesto at 12:00 UTC on July 3. After passing the Yucatán Peninsula, Ernesto turned to the northeast due to the presence of a subtropical ridge to its west. Entering the Gulf of Mexico, Ernesto strengthened into a Category 1 hurricane at 00:00 UTC on July 6 as it approached the state of Florida. Ernesto maintained this intensity until making landfall near Apalachicola, Florida, twelve hours later, and rapidly weakened as it moved inland. At 06:00 UTC on July 7, Ernesto degenerated into a remnant low as it lost tropical characteristics, and its remnants persisted for another eighteen hours before dissipating over Georgia a day later.
The precursor to Ernesto caused four deaths in Central America due to freshwater flooding. An additional death occurred in Florida when rip currents swept away one person as it approached Florida as a hurricane. Ernesto caused a total of $65 million in damages, particularly in the United States.
Hurricane Francine[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | July 11 – July 19 |
|---|---|
| Peak intensity | 120 mph (195 km/h) (1-min) 954 mbar (hPa) |
On July 8, a vigorous tropical wave exited the west coast of Africa. The wave split apart, with its southern portion becoming future Hurricane Gordon and its northern portion spawning a broad low-pressure system on July 10. The system's convection gradually increased, and by midday on July 11, further organization prompted the National Hurricane Center (NHC) to begin issuing advisories on Tropical Depression Six. Six hours later, the depression intensified into Tropical Storm Francine. The storm continued northwestward as it gradually intensified, and on July 13, it entered an area of unusually warm waters and low wind shear and began a period of rapid intensification. At 12:00 UTC that day, Francine intensified into a hurricane and developed an eye feature, and twelve hours later it became a Category 3 hurricane, peaking with winds of 120 mph (195 km/h). Francine also turned westward due to the presence of a large mid-level ridge to its north.
However, shortly after this, northerly wind shear and an eyewall replacement cycle caused Francine to weaken back to a Category 2 hurricane on July 14 at 18:00 UTC and into a Category 1 hurricane twelve hours later. It continued in a northwest direction and gradually weakened to a tropical storm as it approached North Carolina. At 7:20 UTC on July 19, Francine made landfall in Wilmington, North Carolina, as a collapsing tropical storm. Eight hours later, the storm became extratropical over the state of Virginia. The extratropical system continued north before being absorbed by a frontal system over Pennsylvania on July 20.
On July 16, tropical storm warnings were issued for the southeastern United States, particularly in North Carolina and Virginia. Francine brought flooding to eastern North Carolina, with rainfall peaking at 13.4 inches (340 millimeters) in Raleigh. Over 56,000 people were left without power throughout most of Virginia due to strong wind gusts, which peaked at 75 mph (120 km/h). Additionally, two people drowned in Surf City due to storm surge, and another person died in Petersburg, Virginia, from a tornado spawned by the storm. Damages from the storm are estimated at $15 million.
Hurricane Gordon[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | July 16 – July 22 |
|---|---|
| Peak intensity | 145 mph (230 km/h) (1-min) 940 mbar (hPa) |
A tropical wave, the same of which spawned Hurricane Francine, left the western coast of Africa, and the wave fractured, with its northern portion heading northeast and the southern segment continuing westward. The wave continued west at a moderate pace before developing into a tropical depression on July 16 while located 130 miles (210 km) south of Hispaniola. At 06:00 UTC, the tropical depression strengthened into Tropical Storm Gordon to the southeast of Jamaica. Curving northwestward, Gordon rapidly intensified under favorable conditions and was a Category 3 hurricane when it made its first two landfalls in Cuba, one on Isla de la Juventud and another near El Francés. After emerging into the Straits of Florida on July 19, it rapidly intensified again to a Category 4 hurricane and maintained this intensity before making landfall in Englewood, Florida, at 20:00 UTC that day. Gordon rapidly weakened over Florida after landfall, emerging back into the Atlantic Ocean as a minimal Category 2 hurricane twelve hours later. The hurricane continued northeastward along the East Coast of the United States at Category 1 intensity before making another landfall near Morehead City, North Carolina, on July 21 at 10:00 UTC. Twelve hours later, it weakened to tropical storm status and its circulation nearly collapsed. The next day, as Gordon began transitioning into an extratropical cyclone, it made a second pair of landfalls, one on Long Island at 07:00 UTC and another near Bridgeport, Connecticut. The storm transitioned to an extratropical cyclone over Hartford and continued northeast before dissipating over Maine on July 23.
Hurricane Gordon caused widespread devastation throughout its track, following nearly the entire United States' East Coast. In Cuba, Gordon's powerful winds left thousands of people without electricity for up to a week, and the storm surge resulted in the destruction of thousands of structures and the deaths of nearly a dozen people in the country. A large portion of the damage caused by Gordon in the United States was due to Gordon's storm surge of up to 20 ft (6.1 m) in Florida, damaging structures already weakened by Hurricane Ian two years prior. Gordon also pounded the New England region, particularly the states of New York and Connecticut, bringing torrential rain and wind damage throughout the area. Catastrophic flooding and heavy rainfall resulted in the destruction of many structures throughout the two states. In addition, a tornado outbreak occurred in both Florida and New England, resulting in further unprecedented devastation. Overall, Gordon resulted in 97 deaths and left behind nearly $37 billion in damages.
Tropical Depression Eight[]
| Tropical depression (SSHWS) | |
  | |
| Duration | July 25 – July 29 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1006 mbar (hPa) |
On July 22, a tropical wave that would later become Hurricane Helene left the western coast of Africa. The wave continued westward, spawning a low-pressure system to its north on July 25. The newly formed system quickly became a tropical depression, the eighth of the season. However, due to the presence of the Saharan Air Layer to its east, the system was unable to strengthen past tropical depression status, and thus its low-level circulation weakened. At 12:00 UTC on July 26, Eight opened up into a tropical wave and continued towards the Lesser Antilles, away from another trough to its southeast. The system was monitored for potential regeneration, and by 06:00 UTC on July 28, Eight had reorganized into a tropical depression 90 miles southwest of St. Kitts and Nevis. However, just eighteen hours later, the system degenerated into a remnant low south of Puerto Rico and dissipated six hours later.
Hurricane Helene[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | August 2 – August 5 |
|---|---|
| Peak intensity | 90 mph (150 km/h) (1-min) 974 mbar (hPa) |
The same tropical wave that spawned Tropical Depression Eight emerged into the Atlantic Ocean off the west coast of Africa on July 22. The wave initially failed to organize due to the presence of the Saharan Air Layer and the outflow caused by Tropical Depression Eight to its north. By August 1, an area of low pressure had formed south of Jamaica after the tropical wave interacted with an upper-level trough. On August 2, the system gained enough convection to be designated a tropical depression, strengthening into Tropical Storm Helene six hours later. Initial intensification was gradual due to the presence of northerly shear, though Helene was able to organize and intensify into a hurricane as it approached Belize. The system made landfall at peak intensity at 08:00 UTC on August 4 and subsequently weakened after making landfall. The system degenerated into a remnant low a day later and dissipated a few hours later. However, its mid-level circulation survived and later developed into Hurricane Hector in the Pacific Ocean on August 9.
Helene caused widespread flooding in northeastern Honduras. It also produced strong winds, which caused extensive damage to plantation crops in Belize. Structural impacts were moderate, with total economic losses estimated at $60 million. The system also caused flooding throughout southeastern Mexico, and one person drowned in Mexico due to a rip current produced by the hurricane.
Tropical Depression Ten[]
| Tropical depression (SSHWS) | |
  | |
| Duration | August 10 – August 12 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1004 mbar (hPa) |
On August 2, a tropical wave emerged off the coast of Africa and into the Atlantic Ocean. The prevalence of dry air inhibited development until the system reached the Caribbean Sea with the development of a well-defined circulation and an elongated low-pressure system. The storm continued northwestward until it organized into a tropical depression on August 10, when it was located 200 miles (320 km) north of Colombia. The system continued across the Caribbean Sea in a northwest direction, succumbing to dry air and wind shear, and by August 12, Ten became devoid of convection and degenerated into a remnant low while approaching Cuba.
The precursor to Ten brought heavy thunderstorms and significant flooding on the Caribbean coast of South America. Ten caused eleven deaths, ten in Venezuela and another in Colombia. Damages, however, were minimal at best.
Tropical Storm Isaac[]
| Tropical storm (SSHWS) | |
  | |
| Duration | August 18 – August 22 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 999 mbar (hPa) |
Hurricane Kirk[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | August 22 – August 29 |
|---|---|
| Peak intensity | 145 mph (230 km/h) (1-min) 940 mbar (hPa) |
On August 14, the NHC began tracking a tropical wave that had emerged off the west coast of Africa that day. The wave continued westward, was monitored for development, and tracked westward throughout the Caribbean Sea as it became better organized. Late on August 22, a well-defined circulation formed within the disturbance, causing the NHC to designate it Tropical Depression Twelve, just south of Jamaica. The system soon intensified into Tropical Storm Kirk twelve hours later. Initial intensification for its first three days of life was minimal, as vertical wind shear remained prevalent in the western Caribbean Sea. However, as it entered the Gulf of Mexico, it entered more conducive environmental conditions, which allowed the storm to rapidly intensify into a hurricane by 18:00 UTC on August 25 and a Category 4 major hurricane a day later.
The system made landfall in Louisiana with maximum winds of 145 mph (230 km/h) and a minimum pressure of 940 mbar (27.8 inHg) at 00:00 UTC on August 27. This made it the third tropical cyclone in a span of five years to have made landfall in the state at Category 4 intensity. Shortly afterwards, the system turned northeast and began rapidly weakening, falling to tropical storm intensity at 18:00 UTC that day. It continued northeast before weakening into a tropical depression on August 29. Twelve hours later, Kirk degenerated into a remnant low and dissipated over Missouri.
Kirk caused catastrophic wind damage and a storm surge as it approached the state of Louisiana. High winds downed many utility poles and trees throughout the state, and the storm surge reached up to 18 feet (5.5 meters) at Holly Beach. It also produced twenty-four tornadoes, including an EF2 tornado in Mississippi. A total of 89 deaths were attributed to Kirk, all but one of which occurred in the United States. Kirk caused at least $31 billion (2024 USD) in damages, especially in Louisiana.
Hurricane Joyce[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | August 22 – August 29 |
|---|---|
| Peak intensity | 90 mph (150 km/h) (1-min) 976 mbar (hPa) |
Hurricane Leslie[]
| Category 5 hurricane (SSHWS) | |
  | |
| Duration | August 30 – September 9 |
|---|---|
| Peak intensity | 165 mph (270 km/h) (1-min) 916 mbar (hPa) |
The NHC began tracking a tropical wave that exited the west coast of Africa on August 27 for possible tropical cyclogenesis. The tropical wave organized into a tropical depression on August 30 at 12:00 UTC and became Tropical Storm Leslie eighteen hours later. Under an environment conducive for tropical cyclones with minimal wind shear and warm ocean temperatures in the Main Development Region, Leslie intensified at a gradual rate as it curved away from the Lesser Antilles and tracked north of the Caribbean, becoming a hurricane by September 1 at 18:00 UTC. The next day, Leslie began rapidly intensifying north of Puerto Rico, intensifying from a Category 2 hurricane to an intense Category 5 hurricane in less than twenty-four hours. The hurricane also began displaying some annular characteristics, featuring a symmetrical appearance and a large central dense overcast. Soon after peaking with maximum sustained winds of 165 mph (270 km/h) and a minimum central pressure of 916 mbar (24.05 inHg) at 18:00 UTC on September 3, Leslie began an eyewall replacement cycle and encountered drier air, causing it to begin a weakening trend. A day later, it weakened to Category 4 status as it approached the Bahamas.
Leslie made landfall in North Andros at 12:00 UTC on September 5 as a Category 4 hurricane and weakened slightly to Category 3 intensity due to land interaction before making another landfall in Miami-Dade County, Florida, twelve hours later. As Leslie crossed Florida and entered the warm waters of the Gulf of Mexico, it began to re-intensify, turning to the northwest towards the state of Mississippi. Leslie restrengthened into a Category 4 hurricane on September 7 at 06:00 UTC, absorbing the remnants of nearby Tropical Depression Sixteen, and made landfall in the state with winds of 130 mph (215 km/h) twelve hours later. Land interaction and wind shear caused the system to rapidly weaken, falling to tropical storm intensity at 06:00 UTC on September 8. As the system lost much of its convection and became increasingly disorganized, it transitioned into a post-tropical cyclone over Arkansas by 00:00 UTC on September 9. The cyclone persisted for less than a day before dissipating over Michigan.
The storm produced wind gusts of up to 190 mph (305 km/h), which were observed in Haiti. Leslie was the worst hurricane to impact the Bahamas since Hurricane Dorian in 2019, leaving $2.1 billion (2024 USD) in damages and 61 deaths in the country. Despite making landfall in the sparsely populated Andros Island, it passed directly through the country and brought heavy rainfall and wind gusts throughout the nation, causing widespread structural damage and the destruction of over 80% of structures in North Andros. It also made two major hurricane landfalls in the Contiguous United States, causing catastrophic damage. A total of 90 deaths occurred in the United States: 24 in Florida, 33 in Mississippi, 27 in Alabama, and the remaining six deaths occurred in Louisiana. Damage estimates in the country are estimated at $29.5 billion in 2024 USD. In total, Leslie caused 174 fatalities and caused a total of $32.3 billion in damages.Hurricane Milton[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | September 5 – September 15 |
|---|---|
| Peak intensity | 140 mph (220 km/h) (1-min) 948 mbar (hPa) |
Tropical Depression Sixteen[]
| Tropical depression (SSHWS) | |
  | |
| Duration | September 6 – September 7 |
|---|---|
| Peak intensity | 30 mph (45 km/h) (1-min) 1002 mbar (hPa) |
Hurricane Nadine[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | September 8 – September 10 |
|---|---|
| Peak intensity | 75 mph (120 km/h) (1-min) 981 mbar (hPa) |
On August 31, a tropical wave exited the coast of Africa but did not show any significant development until reaching the Caribbean Sea on September 6. On September 7, the tropical wave began interacting with a trough, which resulted in the formation of a tropical depression the day after. The depression intensified into Tropical Storm Nadine at 18:00 UTC. The storm continued west and began a burst of intensification prior to landfall on the Yucatán Peninsula at peak intensity at 19:30 UTC on September 9, reaching hurricane status briefly (operationally, Nadine was considered a high-end tropical storm; however, post-analysis resulted in the storm being upgraded to a brief hurricane). After making landfall, the storm weakened considerably and degenerated into a remnant low after crossing the peninsula. The remnants dissipated on September 11 in the Bay of Campeche.
Tropical storm watches and warnings were issued by the government of Mexico for the northeastern part of the Yucatán Peninsula in anticipation of the storm, resulting in thousands of people evacuating to shelters. The storm produced heavy rainfall and flash flooding throughout the region, resulting in hundreds of homes being damaged due to flooding. Damage from the storm in Mexico is estimated at US$15.46 million (2024 USD). Seven deaths occurred in Mexico, largely due to the landslides and flooding caused by the cyclone.Hurricane Oscar[]
| Category 2 hurricane (SSHWS) | |
  | |
| Duration | September 12 – September 16 |
|---|---|
| Peak intensity | 105 mph (165 km/h) (1-min) 968 mbar (hPa) |
On September 10, a low-pressure system formed north of the Bahamas. The system steadily organized before gaining enough convection to be designated a tropical depression on September 12, becoming Tropical Storm Oscar a few hours later. It began to turn to the northeast due to the presence of a ridge of high pressure over the southeastern United States, strengthening into a Category 1 hurricane on September 13 and making landfall in North Carolina as a Category 2 hurricane the next day at 10:40 UTC. The storm continued along the Mid-Atlantic States as it weakened to a Category 1 hurricane and then to a tropical storm early on September 16, just before completing an extratropical transition. The extratropical system made landfall in Connecticut before dissipating south of Maine the day after.
Hurricane Oscar affected nearly the entire stretch of the United States' East Coast as well as Northeastern Canada, with much of its damage occurring in North Carolina and New England. Its large size and intensity caused widespread flooding across the region, and its storm surge in North Carolina flooded streets and cut off power in Carteret County for days after the storm. The total damage from Oscar amounted to $2 billion (2024 USD). A total of twenty people were killed by the storm, including one that occurred in Quebec.Tropical Storm Patty[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 16 – September 20 |
|---|---|
| Peak intensity | 70 mph (110 km/h) (1-min) 990 mbar (hPa) |
A tropical wave departed the west coast of Africa on September 13. Three days later, it developed into a tropical depression west of Cape Verde. Six hours later, it intensified into Tropical Storm Patty. Gradual intensification soon ensued as the tropical cyclone remained within a favorable environment, reaching a peak intensity of 70 mph (110 km/h) at around 00:00 UTC on September 18. However, the presence of westerly wind shear soon caused the storm to weaken, and Patty entered a hostile environment, weakening to a tropical depression at 18:00 UTC on September 19. The cyclone persisted for the next eighteen hours before it degenerated into an open wave on September 20. The wave continued northwestward before dissipating roughly north of the Lesser Antilles on September 22.
Tropical Storm Rafael[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 19 – September 22 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 993 mbar (hPa) |
On September 18, a low-pressure area formed over the southwestern Caribbean Sea. The system gradually organized until it became a tropical depression the next day in the Yucatán Channel. The depression intensified into Tropical Storm Rafael the next day. The system reached the Gulf of Mexico and began gradually intensifying, continuing northwestward due to the presence of a subtropical ridge to the east. The storm peaked with wind speeds of 60 mph (95 km/h) on September 20 at 18:00 UTC, and an eye-like feature briefly appeared as it approached Texas. The next day, the system made landfall at 3:45 UTC in the state, and began rapidly weakening inland, falling to tropical depression intensity at 18:00 UTC and degenerated into a remnant low on September 22.
Tropical storm warnings and watches were issued along the Gulf Coast as the system approached the area. Rainfall reaching 4.59 in (117 mm) in Houston caused street flooding and minor structural damage. One person also died due to drowning in the floodwaters from the storm. Damage from the system is estimated at $14 million (2024 USD).Hurricane Sara[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | September 20 – September 23 |
|---|---|
| Peak intensity | 90 mph (150 km/h) (1-min) 964 mbar (hPa) |
On September 18, an extratropical cyclone formed in the Central Atlantic. The storm tracked northeastward for several days, reaching unusually warm sea surface temperatures of 77°F (25°C). The storm began a subtropical transition and became Subtropical Storm Sara on September 20 at 12:00 UTC. The system passed through the Azores and gained tropical characteristics, separating from its parent cold-core low and becoming a tropical storm at 12:00 UTC on September 21. The system then intensified further, with the formation of an eye feature, and became a hurricane twelve hours later. Late on September 22, at 18:00 UTC, Sara reached peak intensity with one-minute sustained wind speeds of 90 mph (150 km/h) and an unusually low pressure of 964 mbar (28.47 inHg). After reaching higher latitudes with increased wind shear and colder sea surface temperatures, Sara began weakening and losing tropical characteristics, transforming into an extratropical cyclone on September 23. The extratropical cyclone passed just above Ireland and stuck Great Britain on September 24. The cyclone dissipated in the North Sea the next day.
In the Azores, Hurricane Sara brought gale-force winds and dense precipitation as it passed through the country, leaving thousands of people without electricity for two days. Its extratropical remnants produced wind gusts of up to 100 mph (160 km/h) in Ireland, resulting in many customers losing power due to the storm knocking down power lines and poles. Sara caused €20.1 million (US$21.2 million) in damage throughout the United Kingdom. One death occurred in Ireland when a utility pole was knocked down and crashed into a car, destroying the person inside it.Hurricane Tony[]
| Category 5 hurricane (SSHWS) | |
  | |
| Duration | September 22 – October 2 |
|---|---|
| Peak intensity | 180 mph (285 km/h) (1-min) 901 mbar (hPa) |
- Main article: Hurricane Tony (2024)
On September 19, a westward-moving tropical wave exited the coast of Africa, organizing into a tropical depression on September 22 after obtaining adequate convection and organization to be designated as a tropical cyclone. Shortly after, the system intensified into Tropical Storm Tony. It entered the Caribbean Sea, plateaued in intensity for the next few days, and finally entered more favorable conditions, which permitted the storm's intensification into a hurricane on September 25 at 18:00 UTC, making landfall in Haiti twelve hours later at that intensity. The system made a second landfall in Pilón, Cuba at 18:00 UTC the next day, and twelve hours later, it intensified into a Category 2 hurricane despite land interaction. At 00:00 UTC on September 28, Tony made landfall on Isla de la Juventud, the second storm in the season to do so, and made yet another landfall in Cuba near Pinar del Río six hours later after weakening back to a Category 1 hurricane.
Upon reaching the Gulf of Mexico, Tony entered a very warm environment conducive to strong tropical cyclone activity and began explosively deepening, with its pressure falling from 973 mbar (28.73 inHg) to 901 mbar (26.61 inHg) and winds doubling from 90 mph (145 km/h) to 180 mph (290 km/h) in a 24-hour period. This therefore resulted in Tony becoming the most intense tropical cyclone in the Gulf of Mexico since Hurricane Rita in 2005. Tony maintained Category 5 hurricane intensity for 18 hours, making landfall near Port Sulphur, Louisiana, late on September 29 with a minimum pressure of 905 millibars (26.72 inches of mercury). Land interaction caused the system to begin rapidly weakening, and it made a sixth and final landfall on September 30 at 01:45 UTC near Gulfport, Mississippi, as a high-end Category 4 hurricane. The system rapidly weakened inland, progressing through the Southeastern United States, losing hurricane intensity over Birmingham, Alabama. It was downgraded to a tropical depression over Knoxville, Tennessee, and degenerated into a remnant low over West Virginia on October 2. The remnants persisted until they dissipated over West Virginia twelve hours later.
Hurricane Tony caused catastrophic damage in the states of Louisiana and Mississippi. Total damage from the storm reached $175 billion, cementing it as the single-costliest tropical cyclone on record. The hurricane caused a storm surge of 38 feet (11.8 m), the highest storm surge recorded for an Atlantic hurricane. It penetrated New Orleans' levee system, which was unable to survive Tony's extreme damages, and left the city underwater for over three months. The storm surge also heavily damaged structures along coastal Mississippi and Alabama, causing catastrophic damage. Tony's intense winds and large size caused heavy structural damage hundreds of miles from the landfall region, downing power lines and structures across Mississippi and Louisiana. The storm killed 3,593 people, making it among the deadliest Atlantic hurricanes on record and the second-deadliest United States hurricane, only behind the 1900 Galveston hurricane.
Tony is considered the worst tropical cyclone to impact the United States on record. Recovery efforts were extensive, as the United States federal government spent up to $120 billion in relief and restoring the damage caused by Hurricane Tony, using the funds to rebuild houses and repair the levees that were damaged by the storm.Tropical Storm Valerie[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 30 – October 2 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 1000 mbar (hPa) |
On September 29, a low-pressure system formed in the southwestern Caribbean Sea, and organized into a tropical depression the next day. The depression intensified into Tropical Storm Valerie on October 1 and continued westward. The system then made landfall near the Honduras-Nicaragua border the next day at 1:30 UTC with maximum sustained winds of 50 mph (85 km/h). The system soon weakened inland and dissipated twelve hours later.
Valerie produced gusty winds and heavy rainfall over Central America, leading to flooding and mudslides. In Nicaragua, two deaths related to the storm were reported, and another death was reported in Honduras. Damage was estimated at $12 million USD.Hurricane William[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | October 5 – October 12 |
|---|---|
| Peak intensity | 120 mph (195 km/h) (1-min) 955 mbar (hPa) |
On October 2, a low-latitude tropical wave emerged off the west coast of Africa. Steady organization led to a burst of deep convection, which allowed it to organize into a tropical depression on October 5. After struggling to strengthen at lower latitudes, the system moved northwestward to more favorable conditions, which allowed it to intensify into Tropical Storm William late on October 6. At 00:00 UTC on October 8, the system intensified into a Category 1 hurricane, rapidly intensified into a Category 3 hurricane eighteen hours later, and turned west in response to a subtropical ridge to its north. Moving up to higher latitudes, William began weakening after reaching a peak intensity of one-minute sustained winds of 120 mph (195 km/h), weakening back to a Category 2 hurricane late on October 9 and to a Category 1 hurricane on October 10 at 12:00 UTC. William made landfall on Newfoundland at 15:00 UTC on October 11, retaining tropical characteristics at an unusually high latitude of 52°N. The system underwent an extratropical transition later that day and turned extratropical over the Labrador Sea on October 12. The extratropical system continued north before merging with another extratropical low over Greenland on October 14.
Wind gusts from William knocked down power lines, damaged roofs, and caused customers across the island to lose power, particularly along the Avalon Peninsula. Damages assessed to Newfoundland were estimated at $60 million. In addition, two people died due to a house that collapsed during the storm.Tropical Depression Twenty-five[]
| Tropical depression (SSHWS) | |
  | |
| Duration | October 9 – October 11 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1006 mbar (hPa) |
Hurricane Adria[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | October 10 – October 13 |
|---|---|
| Peak intensity | 75 mph (120 km/h) (1-min) 990 mbar (hPa) |
On September 30, a tropical wave left Africa and progressed westward for several days. Convection remained minimal, and the tropical wave remained disorganized until it reached the Caribbean Sea on October 6. Upon reaching the western Caribbean on October 8, the wave spawned a low-pressure system after interacting with an upper-level trough, and the system began moving northwestward. On October 10, the system soon organized into a tropical depression, intensifying into Tropical Storm Adria twelve hours later. Adria continued strengthening, turned to the west, and intensified into a Category 1 hurricane just before making landfall in Quintana Roo near 00:00 UTC on October 12. It weakened notably after landfall and diminished into a tropical depression near the state of Tabasco. The system then degenerated into a remnant low over the state of Oaxaca the next day, and its mid-level circulation survived, later contributing to the formation of Tropical Storm Miriam in the eastern Pacific.
Adria produced heavy rainfall in southeastern Mexico and Belize, causing structural impacts in the areas. Total economic losses are estimated at $30 million.Hurricane Braylen[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | October 19 – October 26 |
|---|---|
| Peak intensity | 155 mph (250 km/h) (1-min) 913 mbar (hPa) |
- Main article: Hurricane Braylen
On October 8, a tropical wave emerged over the west coast of Africa into the Atlantic Ocean. It moved into the eastern Caribbean on October 17, slowly organizing over the next few days as it took a southerly course. On October 19, it developed into a tropical depression north of Colombia, and strengthened into Tropical Storm Braylen eighteen hours later. Approaching Central America, Braylen entered warm waters and became better organized, and as a result, underwent explosive intensification, peaking as a high-end Category 4 storm right before landfall on Nicaragua with wind speeds of 155 mph (250 km/h). The system rapidly weakened to a tropical storm as it traversed the mountainous terrain of Central America before emerging over the eastern Pacific Ocean early on October 22.
Braylen continued in the Pacific Ocean, curving towards Mexico on October 23 and intensifying into a Category 1 hurricane just before landfall near the Oaxaca and Chiapas border in Mexico, surviving a second crossover as it emerged back into the Atlantic Ocean as a disorganized tropical depression on October 24. It entered unusually favorable conditions in the Gulf of Mexico and reorganized once again, strengthening into a tropical storm and rapidly intensifying into a high-end category 1 hurricane before making landfall near New Orleans, Louisiana on October 26. It weakened as it moved inland and transitioned into an extratropical cyclone over the state of Alabama on October 27. Its extratropical remnants continued over the United States before being absorbed by a frontal low on October 28.
Braylen's impact was widespread and catastrophic due to its unpredictable path and large size. A large amount of the 585 fatalities from Braylen came from Central America, of which Braylen produced a deadly storm surge of up to 31 feet (9.4 m) in Nicaragua and nearby Honduras. It also caused heavy rainfall which in turn led to many deadly landslides throughout Mexico and Central America. Braylen's effects on Mexico were mainly in the form of structural damage, destroying structures and homes throughout the Mexican states of Chiapas and Oaxaca. Its wide circulation affected a large range of areas, extending to countries such as Panama, Guerrero, and Jamaica. In the United States, Braylen brought heavy rainfall and a storm surge and further devastated the areas affected by Hurricane Tony less than a month prior. Wind damage and rainfall accounted for the majority of Braylen's impacts outside of Central America. Damage estimates total up to $7.84 billion (2022 USD).
Tropical Storm Caridad[]
| Tropical storm (SSHWS) | |
  | |
| Duration | October 24 – October 27 |
|---|---|
| Peak intensity | 70 mph (110 km/h) (1-min) 990 mbar (hPa) |
A low-pressure system developed west of Bermuda on October 24. Later that day, the system coalesced into Tropical Storm Caridad as a compact high-pressure system continued to push it southwest and then to the northwest as the high-pressure area moved east. The system remained a tropical storm and peaked with winds of 70 mph (110 km/h) late on October 25, about 400 miles east of North Carolina. The system soon accelerated to the northeast and began weakening slightly after entering an environment with hostile wind shear and colder sea-surface temperatures. The system began losing tropical characteristics and turned extratropical on October 27, well southeast of Nova Scotia, dissipating on October 28.
Tropical Storm Deshawn[]
| Tropical storm (SSHWS) | |
  | |
| Duration | October 31 – November 3 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 995 mbar (hPa) |
In late October, a tropical wave exited the western coast of Africa. On October 31, a burst of convection occurred near the storm's center, thus prompting the National Hurricane Center (NHC) to designate the system as Tropical Depression Twenty-Nine. Shortly thereafter, the system intensified into Tropical Storm Deshawn. The system continued westward and reached its peak intensity with winds of 50 mph (85 km/h) on November 1 at 18:00 UTC, and soon after began weakening due to entering an area with strong vertical wind shear. Late on November 2, the storm was downgraded to a tropical depression, and six hours later, on November 3, it degenerated into a tropical wave.
Deshawn brought heavy rain to the Leeward Islands and the Greater Antilles. Damages remain minimal.Hurricane Emery[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | November 7 – November 10 |
|---|---|
| Peak intensity | 80 mph (130 km/h) (1-min) 991 mbar (hPa) |
On November 7, a non-tropical low formed over the Eastern Atlantic. Later that day, the system gained tropical characteristics and became Tropical Storm Emery, the record-breaking thirtieth named storm of the season. Influenced by a large subtropical ridge, the system turned to the east, away from the Azores. Late on November 9, the storm briefly reached a peak intensity with winds of 80 mph (130 km/h) and a minimum pressure of 991 millibars (29.26 inHg) while located in between Portugal and Morocco. The system also began an extratropical transition after entering an unfavorable environment and completed an extratropical transition as it entered the Alboran Sea on November 10, meaning that it also became the first tropical cyclone ever recorded to enter the Alboran Sea. Later that day, it merged with another extratropical system and became a Mediterranean tropical-like cyclone.
The resulting storm became a subtropical storm, named Cyclone Emery due to Emery's influence on the formation of the cyclone. It caused widespread flooding and landslides across Italy and southern France, leaving roughly $795 million (2024 USD) in damages. It also caused ten fatalities in France and Italy.Tropical Storm Foster[]
| Tropical storm (SSHWS) | |
  | |
| Duration | November 16 – November 20 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 994 mbar (hPa) |
Hurricane Gemma[]
| Category 2 hurricane (SSHWS) | |
  | |
| Duration | December 11 – December 17 |
|---|---|
| Peak intensity | 100 mph (155 km/h) (1-min) 976 mbar (hPa) |
Storm names[]
The following list of names was used for named storms that formed in the North Atlantic in 2024. The names not retired from this list were used again in the 2030 season. This was the same list used in the 2018 season, with the exception of the names Francine and Milton, which replaced Florence and Michael, respectively. The names Francine, Milton, Sara, Valerie, and William were used for the first time this year, as were the auxiliary names Adria, Braylen, Caridad, Deshawn, Emery, Foster, and Gemma (and only in the case of Braylen).

Retirement[]
On April 10, 2025, during the 47th Session of the RA IV Hurricane Committee, the World Meteorological Organization (WMO) retired the names Gordon, Kirk, Leslie, and Tony on List IV of the Atlantic hurricane naming lists and replaced them with Gavin, Kent, Lisette, and Trevor for the 2030 season. The auxiliary name Braylen was also retired; it was replaced with Brody. The retired names will never be used again for another Atlantic hurricane.
With five names retired, it is tied with the 2005 season for the second-highest number of storm names retired after a single Atlantic season. Only the 2029 season saw more with six names.
Season effects[]
This is a table of all the storms that have formed in the 2024 Atlantic hurricane season. It includes their duration, names, landfall(s), denoted in parentheses, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a tropical wave, or a low, and all the damage figures are in 2024 USD. Potential tropical cyclones are not included in this table.
