The 2037 Atlantic hurricane season was an above-average season featuring seventeen named storms, eight hurricanes, and five major hurricanes. It was the most active Atlantic season since the 2034 season, and was another destructive and deadly season, following in the wake of a much less active and damaging season. The season started off with the formation of Tropical Storm Astrid on June 6, which formed over the western main development region, a rare occurrence for that time of year. The first major hurricane of the season, Hurricane Dimitri, formed on August 16 and explosively intensified over the warm waters of the Gulf Stream in the Gulf of Mexico. It later made landfall in the Florida Panhandle, becoming the worst hurricane to impact that area since Hurricane Michael in 2018. The next major hurricane, Clara, formed before Dimitri on August 14, but later intensified into a category 3 hurricane before making landfall on the eastern coast of Florida, causing severe destruction in excess of $4 billion (USD). The month of September saw a multitude of storms forming, as favorable conditions fueled by a rare Modoki El Niño allowed multiple storms to form one after another. September saw the development of ten named storms, four of which became hurricanes, and three of which became major hurricanes. The month featured the strongest storm of the season, Jerry, which became a high-end category 4 hurricane over the eastern Caribbean Sea before devastating Hispaniola. Karen, another major hurricane, formed over the eastern Atlantic and stayed out to sea. Melissa formed in late September over the main development region and meandered over the central Atlantic for 20 days, making it one of the longest-lived Atlantic storms on record. Hurricane Olga formed in late September and intensified into a category 3 hurricane over the Gulf Stream before transitioning into a powerful extratropical cyclone and slamming into Newfoundland. Activity drastically decreased after the start of October, with only two more named systems, Patrick and Rebekah, forming before the end of the season.
The most impactful storms of the season were Dimitri, Imelda, Jerry, and Olga, all of which caused over $5 billion (USD) in damages to the respective areas they impacted. Dimitri explosively intensified into a category 4 major hurricane before making landfall in the Florida Panhandle, becoming the worst hurricane to impact the region since Michael almost 20 years prior. Tropical Storm Imelda, which formed in mid-September, became the most destructive system on record in the state of Maine after making a rare landfall there as a tropical storm. Jerry, the most powerful storm of the season as well as the deadliest storm of the season, formed in mid-September over the main development region and travelled west-northwestward through the Caribbean Sea, making landfall in Hispaniola as a destructive category 4 hurricane. Jerry also impacted other parts of the Caribbean, as well as northeastern Mexico and southern Texas. Hurricane Olga devastated Newfoundland as an extratropical cyclone, becoming the most destructive storm on record for the region.
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 Colorado State University (CSU), among other various agencies. 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.

† Most recent of several such occurrences. | ||||
On December 6, 2036, Tropical Storm Risk (TSR) released their annual extended-range forecast for the 2037 Atlantic hurricane season, calling for a slightly below-average season with 13 named storms, 6 hurricanes, and 2 major hurricanes. They predicted a persistence of the ongoing El-Niño event, albeit a weak one, paired with a continued decline in average SST's across the Atlantic basin, with some regions seeing as low as 1 °C below the average. Four months later on April 5, 2037, TSR increased their prediction to a near-average season featuring 16 named storms, 7 hurricanes, and 3 major hurricanes. They cited a potential increase in SST's over the Caribbean Sea and Gulf of Mexico in response to a developing Modoki-type El Niño, a rare variation of the El Niño which produces favorable conditions for tropical cyclone development in the Atlantic Ocean as opposed to the eastern Pacific Ocean.
On April 11, 2037, Colorado State University (CSU) submitted its own forecast for the 2037 Atlantic hurricane season, predicting a near-average season with 16 named storms, 8 hurricanes, and 3 major hurricanes. They noted the slightly warmer waters in the Caribbean Sea, as well as expected favorable upper-level wind patterns to support tropical development. Pennsylvania State University (PSU) also released their own forecast for the season on April 11, calling for a slightly above-average season with 17 named storms, 9 hurricanes, and 4 major hurricanes. North Carolina State University (NCSU) issued their own forecast for the 2037 Atlantic season on April 20, predicting a below-average season with just 12 named storms, 6 hurricanes, and 2 major hurricanes, citing unfavorable conditions expected across much of the main development region and Caribbean. The University of Arizona (UA) issued their own pre-season forecast on April 30, calling for an above-average season with 18 named storms, 8 hurricanes, and 4 major hurricanes. A day later on May 1, The Weather Company (TWC) issued their forecast for the season, calling for average activity with 16 named storms, 8 hurricanes, and 3 major hurricanes.
On May 9, the United States National Oceanic and Atmospheric Administration (NOAA) issued their first forecast for the 2037 season, calling for a 70% chance that there would be between 14 and 20 named storms, 6 to 9 hurricanes, and 2 to 5 major hurricanes. They cited the expected development of a Modoki ENSO, which would potentially help boost Atlantic activity, especially toward the peak of the season. The United Kingdom's Met Office (UKMO) issued their first forecast for the season on May 12, predicting 15 named storms with a 70% chance that the number would be between 13 and 19, 7 hurricanes with a 70% chance that the number would be between 5 and 9, and 3 major hurricanes with a 70% chance the number would be between 2 and 4. It also predicted an ACE index of 142 with a 70% chance that the index would be in the range 116 to 176.
Mid-season forecasts[]
On June 1, the first day of the official hurricane season, TSR issued an updated forecast, predicting a slightly above-average season with 17 named storms, 8 hurricanes, and 4 major hurricanes. On June 5, TWC released an update to their previous forecast, citing that they expected an average or near average season due to unfavorable upper-level winds over the main development region. On June 16, CSU issued another forecast for the 2037 season, increasing their numbers to 18 named storms, 9 hurricanes, and 4 major hurricanes. They cited the development of a Modoki El Niño which would help boost activity across the Atlantic, especially during the peak months of the season.
On August 1, NOAA issued their final forecast for the 2037 season, concluding that they expected a boost in activity during the peak of the season beginning at the end of August and lasting through the middle of October. Their forecast called for 15-19 named storms, 6-8 hurricanes, and 3-4 major hurricanes. UKMO also issued their final outlook for the season on August 1, predicting that the season would see average activity of 16 named storms, 7 hurricanes, and 3 major hurricanes. They noted that despite the favorable conditions fueled by the Modoki ENSO would likely boost peak season activity, unfavorable upper-level winds over the main development region should hinder significant development over this region.
Seasonal timeline[]
Systems[]
Tropical Storm Astrid[]
| Tropical storm (SSHWS) | |
  | |
| Duration | June 6 – June 9 |
|---|---|
| Peak intensity | 60 mph (95 km/h) (1-min) 996 mbar (hPa) |
On May 31, a tropical wave exited the west coast of Africa. The wave tracked westward over the next week, with dry air and moderate wind shear limiting significant development for much of this time. On June 5, organization began to drastically increase unexpectedly, and the next day, it was upgraded into the first tropical depression of the season. Wind shear continued to afflict the depression as it moved very slowly westward during the next 24 hours. Despite continued wind shear, the depression was able to intensify into Tropical Storm Astrid, the first tropical storm of the season. Astrid turned northward on June 7 through a break in the subtropical ridge, with wind shear relaxing somewhat to allow for additional intensification. On June 8, Astrid attained a peak intensity with winds of 60 mph and a barometric pressure of 996 millibars, making it one of the strongest systems on record in the main development region during the month of June. After reaching its peak intensity, Astrid encountered an area of very strong wind shear, inducing a quick weakening trend. Astrid turned westward once again as ridging became established once again, pushing it further into an unfavorable environment. On June 9, Astrid fell below tropical storm strength as deep convection became increasingly displaced from the low-level center of circulation. Later that same day, Astrid degenerated into a remnant low after it failed to redevelop deep convection. The remnant low persisted west northwestward for the next few days, entering the Caribbean Sea on June 10 and ultimately crossing Puerto Rico before dissipating.
Astrid's impacts in the Lesser Antilles were minor, with only squally weather reported as Astrid's remnant low passed through the region.
Hurricane Barry[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | June 29 – July 5 |
|---|---|
| Peak intensity | 85 mph (140 km/h) (1-min) 975 mbar (hPa) |
On June 21, a tropical wave exited the west coast of Africa. The wave tracked westward during the following week with little to no development. As it approached the Lesser Antilles, the National Hurricane Center (NHC) began to monitor it for potential tropical development during the next seven days. Early on June 29, the NHC began issuing advisories on Potential Tropical Cyclone Two as it neared the Leeward Islands. Two began to curve northwestward as it crossed over the Leeward Islands and entered the northeastern Caribbean Sea later on June 29. That same night, it was upgraded into a tropical depression after flight reconnaissance discovered a closed low-level center amid deep convection. Two began to move briskly northwestward and intensified into a tropical storm on June 30, earning it the name Barry. Tropical Storm Barry made landfall in Puerto Rico shortly afterward as it continued on its quick northwest heading. After crossing Puerto Rico, Barry began to encounter increasing wind shear which displaced a lot of its deep convection away from its low-level center of circulation. Barry weakened into a tropical depression on July 1 as it passed north of Hispaniola and began to decelerate. The depression continued to suffer the effects of strong wind shear as it passed just north of the Turks and Caicos Islands early on July 2. Despite continued strong wind shear, Barry was able to re-intensify into a tropical storm later on July 2 after re-developing a new low-level center of circulation. Wind shear began to relax slightly as Barry curved northward on July 2, allowing for more intensification. As Barry moved away from the Lucayan Archipelago, it began to develop a well-defined core and an eye-like feature. Barry began to accelerate and curved northeastward ahead of an approaching front on July 3, all the while continuing to steadily intensify. On July 4, an eye became evident on satellite imagery, and Barry was upgraded into the first hurricane of the season. Continued intensification occurred, and Barry attained its peak intensity with winds of 85 mph and a barometric pressure of 975 millibars late on July 4. Barry rapidly accelerated northeastward as the frontal boundary to its northwest approached, taking it over progressively cooler waters. This induced extratropical transition on July 5 as Barry passed south of Nova Scotia. Later that same day, Barry fully transitioned into an extratropical cyclone while situated several hundred miles south of Newfoundland. The extratropical cyclone continued to slowly weaken as it slowly passed south of Newfoundland during the next two days. On July 8, the remnant cyclone accelerated northeastward across the north Atlantic before dissipating several hours later.
Impacts from Barry in the Caribbean were minor, with only minimal damages reported in Puerto Rico from rainfall and wind gusts which did not exceed 45 mph. Impacts in the Lucayan Archipelago were also minor, with no damages or fatalities reported from Barry. Sea swelling and rip currents impacted the United States east coast, but no damages or fatalities occurred.
Hurricane Clara[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | August 14 – August 23 |
|---|---|
| Peak intensity | 120 mph (195 km/h) (1-min) 950 mbar (hPa) |
On August 10, a tropical wave exited the west coast of Africa. Tracking westward, the wave began to show signs of organization on August 12. On August 14, it was upgraded into Tropical Depression Three. The depression turned west northwestward and began to intensify the next morning, attaining tropical storm status and receiving the name Clara on August 15. Clara began to decelerate as it approached the Lesser Antilles, meanwhile, favorable conditions allowed for modest intensification during the next few days. On August 17, as Clara began to pass north of the Lesser Antilles, it attained hurricane status as an eye became evident on satellite imagery. As Clara passed north of Puerto Rico, it began a short phase of rapid intensification and attained major hurricane status late on August 18. It subsequently reached its operational peak intensity as a minimal major hurricane with winds of 115 mph and a barometric pressure of 959 millibars. Clara remained a major hurricane for 30 hours before an eyewall replacement cycle induced slight weakening. During this time, Clara began to accelerate northwestward, parallel to the Lucayan Archipelago. Clara began to intensify once again on August 20, re-attaining major hurricane status that night. The following morning, Clara reached its peak intensity with winds of 120 mph, though its pressure continued to drop throughout the day without an increase in sustained winds. Clara passed north of Grand Bahama and made a sharp turn toward the west under the influence of a ridge of high pressure located over the eastern United States. This ridge steered Clara into the eastern coast of Florida on August 22, where Clara made landfall as a weakening category 2 hurricane with winds of 105 mph. Clara quickly weakened after moving inland, and it fell below tropical storm strength later that same day. Clara began to move around the periphery of the ridge, guiding it northward over Georgia as a weakening tropical depression. On August 23, Clara degenerated into a post-tropical low as it accelerated northeastward over the Appalachian region of the United States. The low passed over Lake Ontario on August 24 and curved eastward ahead of a larger extratropical system over Canada. On August 25, Clara's remnant passed over Nova Scotia and emerged back over the Atlantic before being absorbed into the larger extratropical system.
Clara never directly impacted the Lesser Antilles or Lucayan Archipelago, though its outer rainbands brought squally weather to these regions. Sea swelling and rip currents also impacted these areas and Bermuda, causing minor coastal impacts and leading to 1 fatality in the Virgin Islands. In Florida, Clara brought moderate damages to the upper eastern coast, as well as impacts to the Georgia coast. Storm surges were recorded as high as 11 feet in St. Augustine, Florida, where the most significant damages occurred. Wind gusts reached over 120 mph in some places, with rainfall totals exceeding 11 inches in northern Florida and southern Georgia. Clara also brought stormy weather as a post-tropical low to the Appalachian region of the United States, with rainfall totals reaching 7 inches in parts of Tennessee, Kentucky, and West Virginia. Ohio and Pennsylvania also saw heavy rainfall totals of up to 5 inches in some places, resulting in flash flooding and minor damages. In total, Clara was responsible for $3.6 billion (USD) in damages and 9 fatalities, most of which were in the state of Florida.
Hurricane Dimitri[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | August 16 – August 18 |
|---|---|
| Peak intensity | 130 mph (215 km/h) (1-min) 948 mbar (hPa) |
On August 12, a trough of low pressure formed over the western Caribbean Sea, just offshore of Honduras. The low moved erratically east northeastward over the next day or so and began to show signs of organization early on August 15. The low approached the western tip of Cuba late on the 15th and was upgraded into a tropical depression the following morning. The depression passed over the tip of Cuba and entered the Gulf of Mexico just a few hours later while intensifying, and it was upgraded into a tropical storm and named Dimitri just six hours after formation. Dimitri very quickly intensified through the 16th as it passed over sea surface temperatures exceeding 29 °C in association with the Gulf Stream, and it attained hurricane status just eighteen hours later. Dimitri then turned due northward on August 17 and began to rapidly intensify amid very favorable conditions. Flight reconnaissance into the eye of the hurricane found Dimitri to be a major hurricane at 12:00 (UTC) on August 17, with pressures dropping by nearly 3 millibars an hour. Continued rapid intensification occurred, and Dimitri attained category 4 status six hours after being upgraded into a major hurricane. It subsequently attained its peak intensity with winds of 130 mph and a barometric pressure of 948 millibars late on August 17. An eyewall replacement cycle commenced not much longer after Dimitri attained its peak intensity, inducing weakening as the hurricane continued to accelerate due north. On August 18, Dimitri made landfall in the Florida Panhandle as a major hurricane with winds of 120 mph, making it the strongest hurricane to make landfall in the region since Hurricane Michael in 2018, nearly 20 years prior. Dimitri rapidly weakened as it moved inland, falling below hurricane status just five hours after landfall. The storm continued northward over the United States and degenerated into a post-tropical low later on August 18. The remnant low continued inland, passing over Kentucky and Indiana before becoming absorbed into another low on August 19.
Dimitri's landfall in the Florida Panhandle as a major hurricane was severely devastating for the region. The wind field of the hurricane had been increasing in the final eight hours before landfall, with gale-force winds extending outward up to 250 miles from the center of the hurricane. Storm surges in the Florida Panhandle and Alabama reached 15 feet, causing extreme coastal flooding and damages. Pensacola, Florida received the brunt of the hurricane, with wind gusts exceeding 140 mph upon Dimitri's landfall. Many homes, businesses, and other structures were swept away from the rapid storm surge that flooded the area, resulting in numerous damages, injuries, and fatalities. Rainfall totals exceeded 8 inches in parts of Florida and Alabama, causing flash flooding well inland. Dimitri also brought stormy weather to parts of Tennessee, Kentucky, Indiana, and Illinois as a post-tropical low. In total, Dimitri caused $19.7 billion (USD) in damages and was responsible for 72 fatalities, most of which occurred in Florida and Alabama.
Tropical Depression Five[]
| Tropical depression (SSHWS) | |
  | |
| Duration | August 21 – August 24 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1007 mbar (hPa) |
On August 15, a tropical wave exited the west coast of Africa. The wave tracked westward for the next few days with little to no development. On August 19, the wave began to show signs of organization as conditions surrounding it were modestly favorable for development. On August 21, the system was upgraded into Tropical Depression Five while continuing steadily west northwestward. The depression was operationally forecast to reach tropical storm strength before approaching unfavorable conditions over the eastern Caribbean Sea. However, dry air entrainment prevented Five from intensifying beyond depression status as it approached the Leeward Islands. Five made landfall in Guadeloupe on August 23 and continued generally westward into the Caribbean Sea. Early on August 24, wind shear increased drastically, cutting off deep convection from the low-level center of circulation. Continued wind shear resulted in a very disheveled appearance, and satellite imagery was unable to locate a defined center of circulation. This, along with a lack of deep convection, led to the National Hurricane Center declaring Five a tropical wave on August 24. The wave continued westward and entered the eastern Pacific basin, eventually aiding in the development of Juliette.
Impacts in the Leeward Islands from Five were minor, with minimal damages caused by wind gusts reaching 45 mph in parts of Guadeloupe, Montserrat, and Antigua. There were 2 fatalities in Antigua due to these strong wind gusts.
Hurricane Erin[]
| Category 2 hurricane (SSHWS) | |
  | |
| Duration | August 22 – August 31 |
|---|---|
| Peak intensity | 105 mph (165 km/h) (1-min) 963 mbar (hPa) |
On August 20, a tropical wave exited the west coast of Africa. The wave began to show signs of development the following day, and it was upgraded into a tropical depression late on August 22 while situated southwest of the Cabo Verde Islands. The depression began to move briskly northwestward as it moved along the western edge of the Azores High. On August 23, just twelve hours after designations as a tropical depression, it intensified into a tropical and was named Erin. The storm remained on a general northwestward heading across the tropical Atlantic for the next several days, while dry air and light-to-moderate wind shear prevented significant intensification. Erin reached its operational peak intensity as a tropical storm with winds of 50 mph and a barometric pressure of 1002 millibars on August 24. After reaching this intensity, dry air became entrained into the circulation of the storm as wind shear increased, and a slow weakening trend began. Erin fell below tropical storm intensity on August 26 as convection became increasingly limited to the northeastern portion of the system. The depression briefly decelerated over the central Atlantic but remained on a general northwest heading for the next few days. Wind shear relaxed once again on August 27, allowing for Erin to begin intensifying at a quicker rate than it had before. Wind shear continued to decrease as Erin began to curve northward along the periphery of the ridge that had been guiding it throughout its track across the central Atlantic. On August 29, Erin attained hurricane status as an eye became clear on satellite imagery. Continued intensification occurred as Erin passed over slightly warmer waters associated with the Gulf Stream, and it attained category 2 status on August 30. Erin reached its peak intensity with winds of 105 mph and a barometric pressure of 963 millibars later on August 30. Shortly afterward, water temperatures began to drastically decrease as Erin began accelerating northeastward into the higher latitudes. Extratropical transition began late on August 30, a transition which Erin completed the following day, with winds still remaining at hurricane force. Erin's extratropical remnant continued northeastward over the north Atlantic while slowly weakening. It eventually turned northward and then eastward before ultimately dissipating on September 2, several hundred miles southwest of Iceland.
Erin never impacted land during its lifetime.
Tropical Storm Finn[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 1 – September 3 |
|---|---|
| Peak intensity | 40 mph (65 km/h) (1-min) 1005 mbar (hPa) |
On August 31, a tropical wave exited the west coast of Africa. Favorable conditions allowed the wave to immediately begin organizing as it moved west northwestward. Late on September 1, the system was upgraded into a tropical depression while situated south of the Cabo Verde Islands. The depression continued west northwestward and intensified slightly on September 2, receiving the name Finn. Tropical Storm Finn began to suffer the impacts of wind shear and dry air shortly after reaching tropical storm intensity, and it fell to tropical depression status on September 3. Shortly afterward, Finn degenerated into a remnant low after it failed to re-develop deep convection for over twelve hours. The remnant low moved west southwestward as it was steered by strong easterly flow over the deep tropical Atlantic. The remnant was closely monitored for potential redevelopment over the next few days, eventually reaching the Windward Islands before opening up into a trough of low pressure.
Finn never impacted land during its lifetime.
Tropical Storm Gabrielle[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 4 – September 5 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 999 mbar (hPa) |
On August 31, a tropical disturbance spawned an area of low pressure in the eastern Pacific basin, located over the Gulf of Tehuantepec. The low moved northward, crossing Mexico on September 1 and 2. Later on September 2, it emerged over the Bay of Campeche and began to quickly organize. On September 4, the low was upgraded into a tropical depression. The depression continued northward and intensified into a tropical storm, receiving the name Gabrielle early on September 5. Gabrielle curved westward and continued to intensify, attaining a peak intensity with winds of 45 mph and a barometric pressure of 999 millibars late on September 5, just before moving inland over Veracruz, Mexico. Gabrielle rapidly weakened after moving inland and degenerated into a remnant low just a few hours later.
Gabrielle brought heavy rainfall to southern Mexico. Veracruz reported rainfall totals exceeding 14 inches, which resulted in considerable flooding and destructive mudslides. Damages from Gabrielle are estimated around $51 million (USD), and 6 fatalities are directly attributed to the storm.
Tropical Storm Imelda[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 13 – September 15 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 995 mbar (hPa) |
On September 5, a tropical wave exited the west coast of Africa. The wave tracked westward and west northwestward over the next several days with little to no development as wind shear and dry air prevented significant organization. The wave passed north of the Greater Antilles on September 11, where the National Hurricane Center began monitoring it for potential development. After curving northward and passing over the Bahamas, the low began showing signs of organization, and on September 13, it was upgraded into a tropical depression. The depression slowly intensified later that same day and reached tropical storm intensity, receiving the name Imelda. Imelda began to accelerate northeastward, almost parallel to the United States east coast, ahead of an approaching frontal boundary. Warm waters associated with the Gulf Stream allowed Imelda to intensify as it moved further north, and it attained a peak intensity with winds of 50 mph and a barometric pressure of 995 millibars. Imelda continued to rapidly accelerate, and it turned northward toward the upper New England coast on September 14. Baroclinic forcing allowed Imelda to retain its intensity despite sea surface temperatures beneath the storm plummeting as it moved further north. Late on September 14, Imelda made landfall in Maine at peak intensity as it raced northward. Following landfall, Imelda quickly entered extratropical transition and later fully transitioned into an extratropical cyclone over Labrador on September 15. The extratropical remnant was absorbed a few hours later by another extratropical cyclone over eastern Canada.
Imelda brought devastating impacts to parts of Massachusetts and Maine as a large tropical storm. Though it did not directly impact Massachusetts, Imelda's gale-force wind field expanded to over 200 miles from its center of circulation, bringing powerful wind gusts to parts of eastern Massachusetts, namely Cape Cod. Wind gusts reached 70 mph in Chatham, Massachusetts, causing severe destruction to many homes and buildings. In Maine, Imelda's large wind field resulted in storm surges reaching 9 feet as it made landfall. Wind gusts reached hurricane-force in places such as Augusta and Rockland, Maine, causing severe structural damages. Rainfall totals exceeded 16 inches across a good portion of the state, with Ellsworth, Maine recording 21.3 inches of rainfall between September 14 and 15. Damages from Imelda totaled just over $5 billion (USD), making it the costliest tropical cyclone in Maine's recorded history. Imelda was also responsible for 19 fatalities.
Tropical Storm Humberto[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 13 – September 16 |
|---|---|
| Peak intensity | 70 mph (110 km/h) (1-min) 986 mbar (hPa) |
On September 11, a non-tropical, frontal low spawned southwest of the Azores. The low moved westward and began to take on subtropical characteristics on September 12. The following day, the National Hurricane Center upgraded it into a subtropical storm and named it Humberto after it had shed its frontal characteristics. Humberto moved slowly southward during the next two days while steadily intensifying amid favorable conditions. Sea surface temperatures beneath the storm increased as it moved southward, and it began transitioning into a tropical storm on September 14. Late on the 14th, Humberto transitioned fully into a tropical storm and intensified into a high-end tropical storm with winds of 70 mph and a barometric pressure of 986 millibars. Though it was forecast to intensify slightly into a hurricane, wind shear prevented any further strengthening as Humberto began to accelerate toward the east-northeast. Humberto began to slowly weaken as wind shear continued to increase on September 15. Meanwhile, decreasing sea surface temperatures caused Humberto to begin extratropical transition early on September 16. Later that day, Humberto transitioned into an extratropical cyclone while located just north of the Azores. The extratropical remnant continued eastward, eventually passing north of the Iberian Peninsula and moving ashore in France on September 19, where it eventually dissipated.
Humberto never impacted land as a tropical system, though its extratropical remnant brought rainfall and windy weather to parts of Spain and France.
Hurricane Jerry[]
| Category 4 hurricane (SSHWS) | |
  | |
| Duration | September 14 – September 24 |
|---|---|
| Peak intensity | 155 mph (250 km/h) (1-min) 928 mbar (hPa) |
On September 11, a vigorous tropical wave exited the west coast of Africa. The wave tracked westward and began showing signs of organization on September 13. The following day, the wave organized enough to be classified as a tropical depression. The depression slowly intensified and was upgraded into Tropical Storm Jerry early on September 15. As Jerry approached the Leeward Islands, it began to steadily intensify, reaching hurricane status on September 16 while passing north of Barbados. Jerry rapidly intensified into a high-end category 2 hurricane just six hours later, nearly reaching major hurricane status. Shortly after, Jerry made landfall in Martinique, halting intensification for a short period as it crossed over the island and entered the Caribbean Sea. Once Jerry entered the Caribbean Sea, it began to rapidly intensify once again and attained category 4 status on September 17. Continued rapid intensification brought Jerry to near-category 5 intensity, with maximum sustained winds of 155 mph and a barometric pressure of 928 millibars. Though operationally forecast to peak as a category 5 hurricane with winds of 165 mph, Jerry weakened as dry air entrainment disrupted the structure of the hurricane. An eyewall replacement cycle induced further weakening as Jerry approached Hispaniola on September 18. Jerry then made landfall in the Dominican Republic as a low-end category 4 hurricane with winds near 130 mph late on September 18. Quick weakening ensued as Jerry moved over Hispaniola, and it weakened into a minimal hurricane on September 19. Continued land interaction with Hispaniola and Cuba caused Jerry to continue weakening despite moving back over waters on the 19th, and it fell below hurricane intensity later that day. Shortly after weakening below hurricane intensity, Jerry made landfall in eastern Cuba as a strong tropical storm with winds of 70 mph. Jerry continued weakening as it passed over southern Cuba and continued on its quick west-northwestward track. The storm moved back over waters for a short period on September 20, though it later made another landfall in Cuba, this time in the Isle of Youth, with winds of 60 mph. After a third Cuban landfall in the Pinar del Río Province on September 21, Jerry emerged into the Gulf of Mexico. Favorable conditions allowed Jerry to restrengthen, though its passage over multiple landmasses had weakened its inner structure. Still, Jerry managed to reach category 2 hurricane intensity on September 22 as it approached the northeastern coast of Mexico. Jerry attained its secondary peak intensity as a high-end category 2 hurricane with winds of 110 mph and a barometric pressure of 962 millibars on September 23. It then moved inland over northeastern Mexico, several miles south of the Texas border. Jerry rapidly weakened as it moved inland, weakening into a tropical depression on September 24 as it curved northward and moved over southern Texas. Jerry later degenerated into a remnant low on September 24 as it continued to curve eastward and passed over central Texas. The remnant continued eastward before dissipating on September 25 over central Louisiana.
Jerry's impacts throughout the Caribbean were catastrophic, with the worst impacts in Hispaniola. As a category 2 hurricane, Jerry made a direct landfall in Martinique, causing severe damages and destruction from powerful winds and high storm surges. Impacts in Martinique were the worst the island had seen since Hurricane Gia in 2035. Jerry made a catastrophic landfall in the Dominican Republic as a category 4 hurricane, bringing wind gusts in excess of 150 mph and storm surges up to 15 feet. Rainfall totals nearly reached 14 inches in just an eighteen-hour time span, causing catastrophic flooding. Several mudslides occurred in Haiti and the Dominican Republic, devastating many cities throughout both nations and leading to hundreds of fatalities. Jerry also brought minor impacts to Cuba, with wind gusts up to 80 mph reported in the eastern portion of the island nation. Eastern Cuba also had minor impacts from Jerry, though damages here were minimal.
Jerry's impacts in Mexico and Texas were severe, with heavy rainfall totals of 12.5 inches reported in parts of southern Texas and northeastern Mexico. There were 23 fatalities combined in both Mexico and Texas from the impacts of Jerry, and damages were estimated over $1.75 billion (USD), with the majority of this total coming from places in Texas such as Brownsville and McAllen, where rainfall totals were the highest. Including impacts from the Caribbean, Jerry caused a total of $5.4 billion (USD) in damages and was responsible for 345 fatalities, the majority of which were in Hispaniola.
Tropical Depression Twelve[]
| Tropical depression (SSHWS) | |
  | |
| Duration | September 18 – September 20 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1006 mbar (hPa) |
On September 14, a tropical wave exited the west coast of Africa. The wave tracked west northwestward across the tropical Atlantic over the next few days with little to no development. The wave turned toward the north-northwest on September 16 and began to show signs of organization later that evening. On September 18, organization had increased enough for the system to be classified as a tropical depression. The depression continued north-northwest and encountered moderate wind shear over the central Atlantic, preventing any further intensification. On September 20, convection became increasingly limited as wind shear continued to afflict the system. It later degenerated on September 20 after failing to produce convection near its low-level center of circulation. The remnant continued north over the central Atlantic before ultimately dissipating a day later.
Twelve never impacted land during its lifetime.
Hurricane Karen[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | September 19 – September 26 |
|---|---|
| Peak intensity | 120 mph (195 km/h) (1-min) 957 mbar (hPa) |
On September 16, a tropical wave exited the west coast of Africa. It began organizing the following day as it passed south of the Cape Verde Islands. On September 19, organization improved enough for the system to be designated as a tropical depression. The depression turned northwestward and intensified into Tropical Storm Karen eighteen hours later. Karen continued northwestward while steadily intensifying amid favorable conditions. On September 21, Karen reached hurricane status after developing a clear, well-defined eye. Continued intensification occurred, and Karen reached its operational peak intensity with winds of 85 mph and a barometric pressure of 986 millibars on September 22. Karen then abruptly weakened into a minimal hurricane after absorbing dry air located to its north and west later on September 22. After nearly falling below hurricane intensity, Karen eventually fought off the dry air and began to intensify once again on September 23. The hurricane began a curve to the north as it moved through a break in the subtropical ridge. Karen rapidly intensified into a major hurricane on September 24, reaching its peak intensity with winds of 120 mph and a barometric pressure of 957 millibars later that evening. During this time, Karen began to accelerate, bringing it over decreasing sea surface temperatures and into the mid-latitude westerly flow. Karen began weakening on September 25 as it began to move into the higher latitudes, accelerating northeastward ahead of a frontal system. Karen began extratropical transition on September 26 as it quickly weakened, and it eventually transitioned into an extratropical cyclone later that day while situated halfway between Newfoundland and the Azores. The extratropical remnant turned east northeastward and accelerated across the north Atlantic, passing northeast of Ireland before ultimately dissipating on September 28.
Karen never impacted land during its lifetime, though sea swelling was reported in Bermuda, Newfoundland, and the Azores during the hurricane's path across the eastern and central Atlantic.
Tropical Storm Lorenzo[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 21 – September 24 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 1007 mbar (hPa) |
On September 20, a small mesovortex low developed along the east coast of Florida. The low began to develop deep convection as it moved southeastward, and the following day, it was upgraded into a tropical depression. The depression quickly intensified into Tropical Storm Lorenzo just six hours later as it neared Grand Bahama and Great Abaco. Lorenzo turned southwest and eventually northwest as a nearby trough of low pressure formed to its east. This trough pushed Lorenzo northwest through September 22, before the storm eventually turned northeastward ahead of a frontal system. Lorenzo attained its peak intensity as a weak tropical storm with winds of 45 mph and a barometric pressure of 1007 millibars on September 23, before increasing wind shear generated by the frontal system began afflicting it. Lorenzo continued to weaken slowly as it moved northeastward, before ultimately degenerating into a remnant low on September 24 offshore of North Carolina. The remnant low turned eastward before being absorbed into the frontal system the following day.
Lorenzo's impacts in the Bahamas and southeastern United States were minimal, with only squally weather and mildly rough seas reported.
Hurricane Melissa[]
| Category 1 hurricane (SSHWS) | |
  | |
| Duration | September 25 – October 15 |
|---|---|
| Peak intensity | 80 mph (130 km/h) (1-min) 980 mbar (hPa) |
On September 20, a tropical wave exited the west coast of Africa. The wave tracked westward with little to no development during the next 3 days. On September 24, organization began to improve, and the following day, it was upgraded into a tropical depression over the central tropical Atlantic. The depression quickly intensified into Tropical Storm Melissa just six hours later and began a northwestward motion through a break in the subtropical ridge. Melissa faced light to moderate wind shear during the following few days, which restricted quick intensification. Still, Melissa ultimately reached its operational peak intensity as a high-end tropical storm with winds of 70 mph and a barometric pressure of 990 millibars on September 27. After reaching this intensity, Melissa decelerated as it approached a trough of low pressure located northeast of the Lesser Antilles. This trough induced moderate wind shear over Melissa, resulting in weakening and a sharp turn to the east-northeast. As Melissa rotated around the trough, it curved northward and weakened into a moderate tropical storm over the central Atlantic. As Melissa continued to rotate around the trough, it turned northwestward once again; meanwhile, wind shear relaxed, allowing Melissa to begin another round of intensification on September 29. Melissa continued to intensify while moving slowly northwestward, and it attained hurricane status on October 1 after forming an eye. The hurricane reached its second peak intensity with winds of 80 mph and a barometric pressure of 983 millibars on October 1, before abruptly turning southward as it encountered a high-pressure system to its west. Dry air entrainment induced weakening once again as Melissa moved southward, and it fell below hurricane intensity on October 2. Melissa continued to weaken as it turned eastward and east northeastward on October 3 as the high-pressure system began moving northeast. On October 5, Melissa encountered another high-pressure system to its east and turned sharply northward between the two high-pressure systems. The system to Melissa's northeast continued northward, allowing Melissa to turn back toward the west on October 6. This also induced more favorable upper-level wind patterns over the storm, allowing Melissa to resume intensification on the 6th. Sea-surface temperatures along Melissa's path remained around 26-27 °C, which were substantial enough to allow the storm to reach hurricane status once again on October 8. Melissa attained its third peak intensity with winds of 80 mph and a barometric pressure of 981 millibars on October 8. The hurricane then turned northward and eventually northeastward, making its closest approach to Bermuda on October 9. As Melissa moved further north, sea-surface temperatures declined and wind shear increased once again, resulting in weakening below hurricane intensity once again on October 12. Melissa then briefly turned southward once again on October 13 as it approached a system to its north, though turned back toward the north later that day as the other system moved away. Melissa began to accelerate as mid-latitude flow finally picked the small system up; baroclinic forcing allowed Melissa to reach hurricane status once again on October 14, and the hurricane attained its lowest barometric pressure during its duration as a tropical system, with winds speeds of 75 mph and a barometric pressure of 980 millibars. Continued declining sea-surface temperatures resulted in weakening once again on October 15 as Melissa began extratropical transition, and it finally transitioned into an extratropical cyclone on October 15 while located several hundred miles south of Newfoundland. The extratropical remnant continued eastward across the north Atlantic, passing south of Ireland on October 17 and turning southward before dissipating the following day, just a few hundred miles northwest of the Iberian Peninsula.
Despite Melissa remaining a tropical system in the Atlantic for nearly twenty-one days, it never impacted land during this time. Sea swelling and rip currents affected Bermuda, but no damages or fatalities were reported.
Tropical Storm Nestor[]
| Tropical storm (SSHWS) | |
  | |
| Duration | September 26 – September 28 |
|---|---|
| Peak intensity | 50 mph (85 km/h) (1-min) 993 mbar (hPa) |
On September 23, a trough of low pressure formed over the southwestern Atlantic Ocean, midway between the Bahamas and Bermuda. The trough split, forming two separate areas of low pressure over the following few days, with the western low later developing into Olga. The eastern low began showing signs of organization on September 25, and the following day, it had organized enough to be classified as Tropical Storm Nestor. Nestor moved generally northwestward and intensified as it approached North Carolina, reaching its peak intensity with winds of 50 mph and a barometric pressure of 993 millibars on September 27. At the time, Nestor began to appear like a subtropical storm, but maintained enough deep convection to remain a tropical storm. Nestor then made landfall in North Carolina at peak intensity later on the 27th. The storm curved northward and began to accelerate as it crossed the eastern United States ahead of a frontal boundary. Nestor degenerated into a post-tropical cyclone on September 28 over the state of Maryland after losing much of its associated deep convection. The remnant curved northeastward, passing over New England and Labrador before dissipating a few days later.
Nestor's impacts in North Carolina were minor, with only minimal damages from gusty winds and heavy rainfall reported. No fatalities were reported as a result of Nestor.
Hurricane Olga[]
| Category 3 hurricane (SSHWS) | |
  | |
| Duration | September 28 – October 1 |
|---|---|
| Peak intensity | 115 mph (185 km/h) (1-min) 955 mbar (hPa) |
On September 23, a trough of low pressure formed over the southwestern Atlantic Ocean, midway between the Bahamas and Bermuda. The trough split, forming two separate areas of low pressure over the following few days, with the eastern low quickly organizing into Nestor. The western low meandered westward and southward over the next two days, with very limited convection developing due to its proximity to Nestor. After Nestor moved further away on September 27, the low began to show signs of organization. Organization increased enough for the low to be classified as Subtropical Storm Olga on September 28. Olga moved southward and turned eastward on September 29, meanwhile, it began transitioning into a tropical storm as it passed over warmer sea surface temperatures. Later on September 29, Olga transitioned into a tropical storm and began to quickly intensify. Mid-latitude westerly flow began to influence Olga as it continued intensifying, and the storm started moving northeastward on September 29. Olga attained hurricane status late on the 29th as an eye rapidly developed. Rapid intensification ensued on September 30, and Olga reached major hurricane status and its peak intensity with winds of 115 mph and a barometric pressure of 955 millibars later that day. During this time, Olga was quickly accelerating northeastward, passing west and north of Bermuda as a major hurricane. Wind shear increased drastically on October 1, inducing weakening despite the hurricane passing over the warmer waters of the Gulf Stream. Olga began to undergo extratropical transition on October 1 as it passed north of the Gulf Stream and over much cooler sea surface temperatures. Late on the 1st, Olga transitioned into an extratropical cyclone, just a few hours before making landfall in Newfoundland with sustained wind speeds of about 85 mph. Olga's extratropical remnant weakened quickly as it passed over Newfoundland and emerged into the Labrador Sea on October 2. The remnant turned eastward, passing just south of Greenland on October 2 before merging with another extratropical system over the north Atlantic.
Olga brought minor impacts to Bermuda as it passed by the island, with heavy rainfall of up to 7.5 inches from outer rainbands reported. Wind gusts reached hurricane-force in Bermuda, bringing moderated to severe destruction to many buildings and other structures. In total, damages from Olga in Bermuda is estimated just under $30 million (USD).
In Newfoundland, Olga's massive wind field brought hurricane-force wind gusts over almost the entire island province. In Harbour Brenton, where damages from Olga were the most substantial, a wind gust of 133 mph was reported. Many buildings, including homes and businesses, sustained substantial wind damages. Similar wind gusts were reported in the cities of Grand Bank and Fortune. Rainfall totals reached upwards of 20 inches in parts of southern and central Newfoundland, leading to severe damages and multiple fatalities from flooding. Olga's impacts in Newfoundland were considered the worst the island had ever seen. In total, Olga was responsible for $6.2 billion (USD) in damages and 87 fatalities.
Tropical Depression Eighteen[]
| Tropical depression (SSHWS) | |
  | |
| Duration | October 4 – October 5 |
|---|---|
| Peak intensity | 35 mph (55 km/h) (1-min) 1008 mbar (hPa) |
On September 28, a tropical wave exited the west coast of Africa. The wave tracked steadily westward over the next four days with little development. On October 2, organization began to improve, and advisories were initiated on Tropical Depression Eighteen on October 4. Eighteen was not forecast to intensify any more due to being located in an unfavorable environment consisting of strong wind shear. The depression moved steadily west northwestward and failed to intensify further due to the shear. On October 5, convection became increasingly limited, and it later degenerated into a remnant low. The remnant persisted for several more hours before losing its defined low-level circulation and opening up into a trough.
Eighteen never impacted land during its lifetime.
Tropical Storm Patrick[]
| Tropical storm (SSHWS) | |
  | |
| Duration | October 10 – October 11 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 1004 mbar (hPa) |
On October 7, a tropical wave interacted with a shortwave trough over the eastern Caribbean Sea, spawning an area of low pressure. The low drifted westward and began to display signs of organization on October 9. The following day, organization increased enough for the low to be upgraded into a tropical depression. The depression turned northwestward and intensified further into Tropical Storm Patrick later that day. Patrick had a short window for intensification before wind shear was forecast to increase substantially. As Patrick moved northwestward, it intensified and attained its peak intensity with winds of 45 mph and a barometric pressure of 1004 millibars early on October 11. Wind shear increased substantially just hours later, inducing quick weakening as the storm turned northward. Patrick passed just west of Jamaica on October 11 as a weakening tropical storm and curved northeastward. Patrick weakened into a tropical depression hours later, and later degenerated into a remnant low as it moved inland over Cuba. The remnants continued northeastward over Cuba, passing over the southwestern Atlantic Ocean before dissipating the following day.
Impacts from Patrick in Jamaica and Cuba were relatively minor, with only some damages from wind gusts of up to 50 mph in Jamaica reported. There was 1 fatality in Jamaica when these wind gusts knocked down a powerline into a home. Elsewhere, no damages estimates or fatalities were reported.
Subtropical Storm Rebekah[]
| Subtropical storm (SSHWS) | |
  | |
| Duration | November 24 – November 27 |
|---|---|
| Peak intensity | 45 mph (75 km/h) (1-min) 998 mbar (hPa) |
On November 23, a cutoff low formed just offshore of New Jersey along a frontal boundary. The low moved quickly southeastward and began to quickly take on subtropical characteristics as it passed over the warmer waters of the Gulf Stream. On November 24, the low was designated as a subtropical depression after shedding its frontal characteristics. The depression continued southeastward and intensified further into Subtropical Storm Rebekah just six hours later. Rebekah turned eastward and intensified further, reaching its peak intensity with winds of 45 mph and a barometric pressure of 998 millibars on November 26. At the time, Rebekah was a tiny subtropical storm, with very limited convection and an eye-like feature. Rebekah began to weaken later on November 26 as it moved away from the warmer waters of the Gulf Stream, and on November 27, it degenerated into a post-tropical low. The low turned southward once again and meandered over the central Atlantic for several more days before ultimately dissipating on November 30.
Rebekah never impacted land during its lifetime, though Bermuda did report squally weather as the storm passed to its north.
Storm names[]
The following list of names was used for named storms that formed in the North Atlantic in 2037. This was the same list used in the 2031 season, with the exception of the names Clara, Dimitri, Patrick, and Stefan, which replaced the names Chantal, Dexter, Pablo, and Sebastien, respectively. The names Clara, Dimitri, and Patrick were used for the first time this year.

Retirement[]
On March 21, 2038, during the 60th Session of the RA IV Hurricane Commitee, the World Meteorological Organization retired the names Dimitri, Imelda, Jerry, and Olga due to the devastation and loss of life those storms caused, and they will never be used again for another Atlantic hurricane. These names were replaced with Davis, Ina, Jacob, and Olympia, respectively, for the 2043 season.
