The 2036 Atlantic hurricane season was a below-average season featuring ten named storms, five hurricanes, and 3 major hurricanes; the least active season since 2029. The season was also the least destructive season since the 2027 season, despite one major hurricane landfall. The season officially began on June 1, 2036 and ended on November 30, 2036, though formation is possible at any time, as demonstrated by the formation of Subtropical Storm 01L on April 1, which operationally was not considered subtropical. After that, the next named storm did not form until July 29, nearly two months after the official start of the season. The season kicked off after the formation of Ace, and two more systems formed within the next week. The first major hurricane of the season, Chris, formed on August 3 in the western Gulf of Mexico and quickly intensified into a major hurricane before making landfall in Tamaulipas, Mexico at peak intensity. The second major hurricane of the season, Debby, formed on August 24 from a tropical wave in the eastern tropical Atlantic. Debby remained at sea for the duration of its lifespan. The month of September featured several weak systems and one hurricane, Freya, which also remained at sea and only impacted Canada as an extratropical cyclone. After September, the season became extremely quiet, with no tropical disturbances given more than a medium chance for development for much of October. The only system to form during the month of October was also the strongest system during the season, Harriet, which intensified into a category 4 hurricane and brought torrential downpours to parts of the Greater Antilles and Bahamas. After Harriet, another month passed before the next named system, Isaac, which was the last system of the season. Forming on November 18 in the south-central Caribbean Sea just north of Venezuela, Isaac moved northward and impacted Puerto Rico before becoming extratropical on November 20, thus closing the season off.
Despite several land impacts from storms, including one major hurricane landfall, no names were retired after the season, making the 2036 season the first to see no names retired since 2027, nine years prior. Harriet, another major hurricane, impacted parts of the Bahamas during the time of its peak intensity, bringing hurricane-force winds to some islands, specifically Great Abaco. Despite this, damages were not severe as the eye of the storm remained offshore. The deadliest and most impactful storm, Isaac, caused over 30 fatalities in parts of the Greater Antilles, but was otherwise not a very destructive storm. With less than $1 billion (USD) in damages dealt throughout the entire season, the 2036 Atlantic hurricane season is one of the least destructive seasons on record, and the least destructive since 2027.
Seasonal forecasts[]
In advance of, and during, each hurricane season, several forecasts of hurricane activity are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States National Oceanic and Atmospheric Administration (NOAA)'s Climate Prediction Center, Tropical Storm Risk (TSR), the United Kingdom's Met Office (UKMO), and Philip J. Klotzbach, William M. Gray and their associates at Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to NOAA and CSU, the average Atlantic hurricane season between 2001 and 2030 contained roughly 16 tropical storms, 8 hurricanes, 4 major hurricanes, and an accumulated cyclone energy (ACE) index of 82–135 units. Broadly speaking, ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of 39 mph (63 km/h). NOAA typically categorizes a season as above-average, average, or below-average based on the cumulative ACE index, but the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is sometimes also considered.

On December 8, Tropical Storm Risk (TSR) released their extended range forecast for the 2036 Atlantic hurricane season, predicting below-average activity with 12 named storms, 5 hurricanes, and 1-2 major hurricanes. Reasonings given for this prediction included a forecasted powerful El Niño–Southern Oscillation (ENSO), which was expected to be in the height of the warm phase by the middle of the annual hurricane season. TSR would update its forecast four months later on April 12, 2036, which adjusted their numbers slightly lower to 11 named storms, though 5 hurricanes and 2 major hurricanes were still forecast.
On April 14, 2036, Colorado State University (CSU) released their first prediction for the 2036 season, calling for below-average activity with 12 named storms, 6 hurricanes, and 2 major hurricanes. The Weather Company (TWC) also issued their first prediction for 2036 on April 14, calling for only 10 named storms, 5 hurricanes, and 1 major hurricane. They stated the cooler-than-average sea surface temperatures, as well as strong wind shear and dry air, which was forecast to plague the tropical Atlantic throughout much of the season, would most likely inhibit tropical activity. On April 30, North Carolina State University released their own forecast for the season, predicting 11 named storms, 5 hurricanes, and 2 major hurricanes.
On May 7, NOAA released its first forecast for the season, calling for a 70% chance that there would be between 8 and 14 named storms, 3 to 7 hurricanes, and 1 to 3 major hurricanes. Reasonings given for this prediction were higher-than-average trade winds and lower-than-average sea surface temperatures expected across most of the tropical Atlantic, Caribbean Sea, and Gulf of Mexico throughout the entire season due to the strengthening ENSO. On May 9, the United Kingdom Met Office (UKMO) issued a forecast of a below-average season. It predicted 11 named storms with a 70% chance that the number would be between 8 and 14, 5 hurricanes with a 70% chance that the number would be between 3 and 7, and at least 1 major hurricane with a 70% chance the number would be between 1 and 3. It also predicted an ACE index of 102 with a 70% chance that the index would be in the range 56 to 110.
Mid-season forecasts[]
On the first day of the hurricane season, CSU released an update of their previous prediction, stating they expected the season to see below-average activity on account of dry air and cooler-than-average SST's limiting significant tropical development. TWC updated their forecast slightly upward on July 1 to 11 named storms, 5 hurricanes, and 2 major hurricanes. TSR also issued an updated forecast a few days later on July 5, adjusting their numbers downwards due to the lack of tropical disturbances during the majority of the first month of the hurricane season. On August 7, UKMO issued their final forecast for the season, concluding that they expected the season to produce below-average activity with 11 named storms, 5 hurricanes, and 2 major hurricanes. NOAA released their final forecast for the season on August 8, predicting the season would conclude with 10-16 named storms, 4-8 hurricanes, and 1-3 major hurricanes.
Seasonal timeline[]
Systems[]
Unnamed subtropical storm[]
| Tropical storm (SSHWS) | |
  | |
| Duration | April 1 – April 2 |
|---|---|
| Peak intensity | 40 mph (65 km/h) (1-min) 999 mbar (hPa) |
On March 29, a non-tropical low spawned along the tail-end of a frontal boundary located over the central north Atlantic. The low moved westward and was monitored for potential subtropical development, though this was considered unlikely due to the unfavorable environment surrounding it, and it was only given a 20% chance of development. The low moved east southeastward and continued to display subtropical organization, despite continued forecasts for no development. Operationally, the low was not considered subtropical, though post-analysis indicated the low had transitioned into a subtropical cyclone at 18:00 UTC on April 1 while located south of the Azores, and it was re-designated as Subtropical Storm 01L. The low moved quickly to the east and curved northward around the Azores as it was steered by a large and powerful cyclone to its north. The storm attained its peak intensity with winds of 40 mph and a barometric pressure of 999 millibars on April 2 as it began to transition into an extratropical cyclone. Later on April 2, the storm completed extratropical transition as it turned north, moving around the larger cyclone. The following day, the remnants of the storm were absorbed into the larger system.
The storm brought minor impacts to the Azores, with rainfall totals of up to and exceeding 5 inches in some places. Damages were minimal, and no fatalities were reported.
Hurricane Ace[]
| Category 2 hurricane (SSHWS) | |
  | |
| Duration | July 29 – August 8 |
|---|---|
| Peak intensity | 105 mph (165 km/h) (1-min) 971 mbar (hPa) |
On July 25, a tropical wave exited the west coast of Africa. Unfavorable conditions in the deep tropical Atlantic, which had persisted throughout the first two months of the season, limited significant development during the next few days as the wave moved westward. On July 27, the wave began to show signs of development despite moderate wind shear and dry air surrounding it. On July 29, the system was upgraded into a tropical depression while located several hundred miles east of the Windward Islands. The depression moved steadily west northwestward and continued to fight off less than favorable conditions, strengthening into Tropical Storm Ace later on the 29th. As Ace approached the Windward Islands, wind shear relaxed somewhat, allowing for modest intensification. Ace reached an initial peak intensity with winds of 65 mph and a barometric pressure of 995 millibars on July 31 after entering the Caribbean Sea. Ace maintained this intensity for several hours before wind shear increased once again, resulting in weakening. Ace began to decelerate on August 1 as it passed south of Hispaniola, with continued wind shear impacting the storm. After another day of moderate wind shear, Ace turned northwestward and began a slow strengthening trend as wind shear began to relax once again. On August 3, Ace made landfall in Grand Cayman as a moderate tropical storm with winds near 60 mph. The storm continued northwest and attained a secondary peak intensity with winds of 70 mph and a barometric pressure of 991 millibars on August 5 after entering the Gulf of Mexico. After a brief pause in intensification, Ace intensified further into a hurricane on August 6. Ace continued to intensify as it approached the Texas coast, and it attained category 2 status on August 7. Ace reached its peak intensity with winds of 105 mph and a barometric pressure of 971 millibars later that day, just before moving inland over south-central Texas. Ace quickly weakened as it moved inland, curving westward and west southwestward as it became increasingly shallow. On August 8, Ace degenerated into a remnant low over northern Mexico, and further dissipated a few hours later.
Ace brought minor impacts to parts of the Caribbean as it passed through the region. In the Windward Islands, only minor damages from gale-force wind gusts were reported. Grand Cayman also sustained minor impacts from Ace, with a total of $10 million (USD) in damages reported; no fatalities occurred from Ace in the Caribbean. In Texas, Ace made landfall in a relatively rural area, which helped limit significant impacts. Still, storm surges over 7 feet were reported in multiple places along the Texas coast. Rainfall totals exceeded 8 inches in parts of central and southern Texas, namely in the San Antonio and Austin areas. Wind gusts of near hurricane-force were reported in Austin, resulting in some significant structural damages. Damages in Texas exceeded $500 million (USD), and Ace was responsible for 3 fatalities.
Tropical Storm Bella[]
| Tropical storm (SSHWS) | |
  | |
| Duration | August 2 – August 7 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 997 mbar (hPa) |
On July 31, a tropical wave exited the west coast of Africa. The wave began immediately showing signs of organization as it tracked westward and passed south of the Cabo Verde Islands. On August 2, the wave had organized enough to be classified as a tropical depression. The depression continued to intensify and was upgraded into a tropical storm and named Bella the following day. Bella continued quickly westward while steadily intensifying amid favorable conditions, attaining a peak intensity with winds of 60 mph and a barometric pressure of 997 millibars on August 5. After peaking, wind shear began to increase, resulting in weakening as Bella approached the Leeward Islands. On August 7, Bella made landfall in Guadalupe as a minimal tropical storm; land interaction and continued wind shear caused Bella to weaken further into a tropical depression as it entered the Caribbean Sea. As Bella lost most of its associated convection, it degenerated into a remnant low later on August 7 as it passed south of the Virgin Islands. The remnant continued west northwestward, passing south of Puerto Rico and The Dominican Republic before opening up into a trough of low pressure on August 8.
Impacts in the northeastern Caribbean from Bella were minimal, with only minor damages reported in places such as Guadalupe and Montserrat. No fatalities were reported as a result of Bella.
Hurricane Chris[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | August 3 – August 6 |
|---|---|
| Peak intensity | 115 mph (185 km/h) (1-min) 966 mbar (hPa) |
On August 1, a low-pressure tropical disturbance formed within an area of convective thunderstorms over the Yucatan Peninsula and Bay of Campeche. The low drifted northwestward and began showing signs of development on August 2. The following day, organization improved substantially, and it was upgraded into a tropical depression. The depression curved west northwestward and intensified into Tropical Storm Chris twelve hours later. Amid very favorable conditions, Chris began rapidly intensifying on August 4 as it continued west northwestward. Chris attained hurricane status early on August 4 after developing an evident eye on satellite imagery. Continued intensification occurred, and Chris attained major hurricane status on August 5 as it closed in on the Mexico coastline. After attaining its peak intensity with winds of 115 mph and a barometric pressure of 966 millibars, Chris made landfall in Tamaulipas, Mexico at peak intensity. The hurricane rapidly weakened as it moved inland, falling below hurricane status nine hours later. Chris turned northwestward and eventually northward, approaching the Rio Grande River before ultimately degenerating into a remnant low on August 6. The remnant moved over southern Texas before dissipating several hours later.
Despite making landfall in northern Mexico as a major hurricane, impacts from Chris were relatively minor due to its landfall in a rural area. Several coastal villages were significantly damaged from the major hurricane, with wind gusts reported to be up to 125 mph around where the northern eyewall moved inland. Rainfall totals also reached and exceeded 14 inches in some locations. Southern Texas also received rainfall totals nearing 10 inches, resulting in minor flood damages. Total damages are estimated around $100 million, with 4 fatalities directly linked to impacts from Chris.
Hurricane Debby[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | August 24 – September 3 |
|---|---|
| Peak intensity | 115 mph (185 km/h) (1-min) 956 mbar (hPa) |
On August 20, a tropical wave exited the west coast of Africa. Tracking westward, the wave began to show signs of organization, and by August 24, it had developed into a tropical depression. Continuing swiftly westward, the depression intensified and was named Debby just six hours after being designated. Debby continued to intensify amid favorable conditions as it continued westward. On August 25, Debby turned northwestward as it moved around the periphery of the subtropical ridge. Continued intensification occurred, and Debby attained hurricane status late on August 26 as it continued northwestward. Debby's intensification slowed on August 27 and halted on August 28 as it moved into an area of moderate wind shear. Still, Debby was able to fight off the shear as it grew in size, with a gale-force wind field expanding up to 425 nautical miles from the center. After moving into an environment with less wind shear, Debby resumed intensification and was upgraded into a category 2 hurricane late on August 28. Debby's large size prevented rapid intensification as it continued northwestward and decelerated. Intensification continued, however, and Debby attained major hurricane status late on August 29, reaching peak winds of 115 mph. Though Debby's winds remained at 115 mph, its pressure continued to drop, and Debby reached an operational peak intensity with winds of 115 mph and a barometric pressure of 958 millibars on August 30. Later that same night, Debby's eye became briefly ill-defined, prompting slight weakening below major hurricane status. This was short-lived, and Debby reattained major hurricane status the next morning after improving in organization once again. Debby subsequently attained its peak intensity with winds of 115 mph and a barometric pressure of 956 millibars on August 31. After peaking, an eyewall replacement cycle caused another temporary weakening trend, and Debby fell below major hurricane status on later that same day as it turned sharply northward ahead of an approaching trough. On September 1, as Debby began to accelerate northeastward, it passed over warmer waters associated with the Gulf Stream and intensified back into a major hurricane, reaching its tertiary peak intensity with winds of 115 mph and a barometric pressure of 958 millibars. After holding major hurricane status for another 12 hours, Debby began to pass over cooler sea surface temperatures and weakened once again. The hurricane began steadily weakening as wind shear also began to increase, and Debby fell below category 2 status on September 2. Debby began to transition into an extratropical cyclone on September 2 as it passed south of Newfoundland, a process it completed the following day. The extratropical cyclone continued northeastward and turned eastward over the north Atlantic while slowly weakening. After executing a clockwise loop on September 5 to the north-northwest of the Azores, Debby's extratropical remnant turned northward and eventually northwestward. On September 7, Debby's remnant dissipated roughly 200 miles east of the southern tip of Greenland.
Debby never impacted land during its lifetime, though rough seas and rip currents were generated in parts of the Greater Antilles, as well as along the North American Atlantic coastline and in Bermuda. Gale-force wind gusts impacted parts of Nova Scotia and Newfoundland as Debby passed to the south and east, though damages were minimal.
Tropical Depression Six[]
| Tropical depression (SSHWS) | |
  | |
| Duration | August 26 – August 27 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1006 mbar (hPa) |
On August 22, an area of low pressure formed in the northwestern Caribbean Sea. Unfavorable conditions prevented significant development, and the low moved over the Yucatan Peninsula and entered the Gulf of Mexico on August 24. The low began to organize on August 25 as it moved steadily northwestward, and it was classified as Tropical Depression Six the following day. Six was forecast to intensify into a minimal tropical storm before making landfall in northern Mexico, however, dry air intrusion prevented intensification. Late on August 26, Six made landfall in northern Tamaulipas, Mexico with winds of 35 mph and a barometric pressure of 1006 millibars. Six weakened as it moved inland, and it degenerated into a remnant low on August 27. The remnant continued inland and eventually dissipated a few hours later.
Impacts from Six in Mexico and southern Texas were minor, with some areas receiving up to 5 inches of rainfall. Areas which had been impacted by Chris earlier in the month were still recovering, and impacts from Six halted recovery efforts. Still, damages remained minimal, though there were two fatalities in Tamaulipas.
Tropical Storm Ernesto[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 2 – September 5 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 1004 mbar (hPa) |
On August 28, a tropical wave exited the west coast of Africa. The wave tracked westward during the next few days and began to show signs of organization on August 31. Two days later, the NHC designated the system as Tropical Depression Seven. The depression continued generally westward and intensified into Tropical Storm Ernesto just a few hours later. Ernesto was located in only modest conditions at the time of naming, with moderate wind shear impacting the system. Ernesto was able to intensify slightly however and reached a peak intensity with winds of 45 mph and a barometric pressure of 1004 millibars on September 3. Ernesto continued to battle moderate wind shear as it continued westward and was unable to intensify further as it approached the Leeward Islands. Wind shear increased late on September 4, causing Ernesto to begin weakening. Ernesto fell below tropical storm strength on September 5 as it passed north of Anguilla, with convection being extremely limited to the northwestern portion of the system's circulation. Just twelve hours after weakening into a tropical depression, satellite imagery was unable to detect a center of circulation, indicating that Ernesto had opened up into a tropical wave. The wave continued west northwestward and dissipated two days later over the Bahamas.
Impacts in the Lesser Antilles from Ernesto were minor, with only squally weather reported as the system made its closest approach. The remnant wave also brought squally weather to parts of the Bahamas on September 7, though no damages or fatalities were reported.
Hurricane Freya[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | September 5 – September 13 |
|---|---|
| Peak intensity | 85 mph (140 km/h) (1-min) 981 mbar (hPa) |
On September 1, a tropical wave exited the west coast of Africa. Tracking north of due west, the wave began to show signs of organization the following day. On September 4, organization improved drastically, and the following day, it was upgraded into a tropical depression. Facing modest wind shear and dry air, the depression struggled to intensify for the next day or so as it continued west northwestward under a strong subtropical ridge. Still, on September 6, the depression was able to intensify into a tropical storm and was named Freya. The storm was slow to intensify at first as it was still facing wind shear, although it was moving into more favorable conditions on September 7. After struggling to organize itself, Freya began to more quickly strengthen on September 8 as it solidified a well-defined core under deep, organized convection. On September 9, Freya achieved hurricane status as an eye became evident on satellite imagery. The hurricane then began to turn northward as it approached a weakness in the subtropical ridge. Freya continued to steadily intensify and attained its peak intensity with winds of 85 mph and a barometric pressure of 981 millibars on September 10. After peaking, Freya's eye became somewhat less defined, prompting a slight weakening, though not below hurricane status. Freya retained hurricane status for the next two and a half days as it travelled east of due north. Freya began to accelerate toward the northeast on September 12 as an approaching system guided it. The next day, Freya transitioned into an extratropical cyclone and began to turn sharply northwestward as it absorbed the other system. Freya's extratropical remnant continued northwest, eventually passing over Newfoundland and the Gulf of St. Lawrence before moving over Labrador and ultimately dissipating on September 15.
Freya never impacted land as a tropical system, though it did impact Atlantic Canada as an extratropical cyclone. Wind gusts of up to hurricane-force were reported in Newfoundland as Freya made its closest approach, and over 10 inches of rainfall fell in some locations. Rip currents and rough seas were also reported in parts of the Lesser Antilles and in Bermuda during Freya's journey across the Atlantic. Damages from winds and flooding in Canada totaled over $90 million (USD); there were no reported fatalities as a direct result of Freya.
Tropical Storm Glenn[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 10 – September 13 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 1002 mbar (hPa) |
On September 8, a tropical wave exited the west coast of Africa. The wave began to quickly organize amid modestly favorable conditions as it moved generally westward. On September 10, organization had improved enough for it to be classified as a tropical depression. The depression began to curve west northwestward and intensified into Tropical Storm Glenn the following morning. Glenn began to intensify quickly despite a pocket of dry air located to its northeast. Early on September 12, Glenn attained its peak intensity with winds of 60 mph and a barometric pressure of 1002 millibars. After peaking, wind shear began to increase and Glenn began to weaken. Convection became increasingly limited on September 13, and Glenn was classified as a remnant low later that same morning. The remnant turned westward and remained on this general heading for the next day or so before opening up into a trough of low pressure late on September 14.
Glenn never impacted land during its lifetime, though its precursor wave brought squally weather to the Cabo Verde Islands.
Tropical Depression Ten[]
| Tropical depression (SSHWS) | |
  | |
| Duration | September 17 – September 19 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1009 mbar (hPa) |
On September 12, a tropical wave exited the west coast of Africa. Dry air prevented any organization as the wave moved just south of due west under the influence of a strong subtropical ridge. On September 15, the wave began to show signs of organization as convection became increasingly deep. Organization improved enough for the system to be classified as a tropical depression, the tenth of the season, on September 17 while it was located roughly 1000 miles east of the Windward Islands. Wind shear began to increase shortly after designation on September 17, limiting any chances of intensification as the depression moved west northwestward. Ten approached the Windward Islands on September 19, and it made landfall in St. Lucia early that morning wind winds near 30 mph. After entering the Caribbean Sea, Ten degenerated into a remnant low as there was little to no remaining convection near the center of circulation. The remnant persisted for several more hours before ultimately opening up into a trough of low pressure.
Impacts in the Windward Islands from Ten were minor, with only squally weather and minimal wind damages reported as it passed over St. Lucia.
Hurricane Harriet[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | October 16 – October 22 |
|---|---|
| Peak intensity | 145 mph (230 km/h) (1-min) 935 mbar (hPa) |
A tropical wave exited the west coast of Africa late on October 6. The wave moved steadily westward during the next several days and eventually merged with another tropical disturbance located over the central tropical Atlantic. The new system meandered over the central Atlantic for a few days before continuing slowly west northwestward on October 10. The system approached the Leeward Islands on October 14 and began to show signs of organization, with the NHC designating it as Potential Tropical Cyclone Eleven early the following morning. After entering the Caribbean Sea, Eleven continued to improve in organization and was designated as a tropical depression early on October 16. The depression continued slowly west northwestward and struggled to intensify initially as it fought moderate wind shear. Twenty-four hours after being upgraded into a tropical depression, it finally intensified and was named Harriet. The storm began to turn northwestward though a weakness in the subtropical ridge that had guided it westward for most of its life. Harriet intensified somewhat as it neared the western coast of Puerto Rico, clipping it late on October 17 and subsequently emerging into the southwestern Atlantic. Harriet began to accelerate as a developing trough to its northeast began to influence it. Harriet continued to slowly intensify as it moved further northwest, and it attained hurricane status on October 19. Harriet moved parallel to the Lucayan Archipelago and began to rapidly intensify as wind shear relaxed. The hurricane reached major status late on October 19, and further attained category 4 status at 00:00 UTC on October 20. Continued intensification occurred, and Harriet attained its peak intensity with winds of 145 mph and a barometric pressure of 935 millibars later on October 20. During this time, Harriet decelerated as the trough to its northeast moved away, and the hurricane made a close approach to Great Abaco, narrowly avoiding landfall. Harriet turned northward as a front approached the hurricane to its northwest. Weakening began on October 21 as wind shear induced by the front began to affect the hurricane. Harriet fell below category 4 status on October 21 as it began to quickly accelerate northeast ahead of the front. Harriet further weakened below major hurricane status as sea surface temperatures began to drop. Harriet quickly moved over the Gulf Stream on October 22 which allowed the hurricane to retain category 2 status. Harriet quickly entered extratropical transition later on October 22, a process which it completed late that same night. The extratropical cyclone continued to weaken and passed over Nova Scotia with hurricane-force winds. The cyclone curved more eastward over the Gulf of St. Lawrence and passed over Newfoundland on October 23. The extratropical cyclone then accelerated quickly northeast across the northern Atlantic, passing south and east of Greenland on October 24 and 25 before ultimately dissipating on October 26, roughly 200 miles west of Iceland.
Harriet had only minor impacts throughout its lifetime despite impacting multiple locations. Heavy rainfall of up to 5 inches fell in parts of the Lesser Antilles, though damages remained minimal. In Puerto Rico, wind gusts reaching 60 mph caused moderate structural damages along with storm surges and rainfall. Damages here are estimated around $50 million (USD), and 1 fatality occurred in Puerto Rico.
Despite approaching Great Abaco near peak intensity, Harriet's impacts were minimal, with the strongest winds of the hurricane staying offshore. Still, wind gusts reached and exceeded 100 mph, causing moderate structural damages and downing many trees and power lines. Rainfall totals in Great Abaco of 11.4 inches were reported, which resulted in flash flooding and moderate water damages. Damages throughout the Bahamas exceeded $125 million (USD), though this was mostly limited to Great Abaco. No fatalities were reported in the Bahamas.
In Canada, Harriet's extratropical remnant brought severe weather with rainfall totals exceeding 5 inches and wind gusts of up to 90 mph. Snowfall was also reported in Labrador and parts of Newfoundland as Harriet passed through. Damages reached $85 million (USD) in Canada, with 4 fatalities attributed to Harriet here. Throughout its lifetime, Harriet was responsible for $260 million (USD) in damages and 5 direct fatalities.
Tropical Storm Isaac[]
| Tropical storm (SSHWS) | |
  | |
| Duration | November 18 – November 20 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 995 mbar (hPa) |
On November 15, an area of low pressure spawned within a convectively coupled Kelvin Wave located near Trinidad and Tobago. The low moved westward and entered the Caribbean Sea the following day, where it was monitored for potential development. Two days later, advisories were initiated on Tropical Depression Twelve. The depression turned sharply northward and intensified into Tropical Storm Isaac the following morning. Isaac began to accelerate northward as it interacted with a large trough to its northwest. Located over the warm waters of the Caribbean, Isaac was able to intensify despite moderate wind shear, and it attained its peak intensity with winds of 50 mph and a barometric pressure of 995 millibars on November 20, just as it was making landfall in Puerto Rico. Interaction with the trough to its northwest caused Isaac to begin extratropical transition on November 20 despite still being located over the Caribbean Sea. After emerging into the southwestern Atlantic, Isaac completed extratropical transition and began to curve northeastward. The following day, Isaac merged with a frontal boundary located several hundred miles southwest of Bermuda.
Impacts in the Caribbean from Isaac were relatively minor, with squally weather affecting parts of Columbia and Venezuela. In Puerto Rico, wind gusts in excess of 60 mph, along with rainfall totals reaching 16 inches in some places, led to moderate and severe damages in areas that had been impacted by Harriet a month prior. Damages totaled $40 million (USD) in Puerto Rico, and 33 fatalities occurred when a building collapsed due to a combination of flooding and strong wind gusts.
Storm names[]
The following list of names was used for named storms that formed in the North Atlantic in 2036. This was the same list used in the 2030 season, with the exception of the names Ace, Bella, Glenn, Remy, and Sabrina, which replaced Alberto, Beryl, Gordon, Ryder, and Sara, respectively.

No names were retired this year, so this same list will be used again in the 2042 Atlantic hurricane season.
