Hurricane Oscar was a compact tropical cyclone,with the smallest hurricane-force wind field on record in the Atlantic,which caused moderate damage in eastern Cuba in late October 2024. [1] The fifteenth named storm and tenth hurricane of the 2024 Atlantic hurricane season,Oscar originated from a very long-lived tropical wave which moved off of the west coast of Africa on October 10. It did not undergo tropical cyclogenesis until October 19,due to adverse atmospheric conditions. On that same day,the compact storm had a round of rapid intensification and became a Category 1 hurricane. After peaking in wind intensity,Oscar remained steady in intensity as it moved slowly towards Cuba,making landfall late on October 20 with slightly weaker winds but at peak pressure intensity. Land interaction severely disrupted the small storm,and Oscar emerged north of Cuba as a minimal tropical storm with a poorly-defined center. Unfavorable conditions continued to hamper the small storm,and Oscar later dissipated on October 22 after opening into a trough.
Due to the rapid development of Oscar,preparations were sudden across the Greater Antilles. Hurricane watches and warnings were issued across the Turks and Caicos Islands,Southeastern Bahamas,and Cuba on October 19. Eight people were confirmed to have died as a result of Oscar,all in Cuba,which was amplified by a severe national power outage. As of December 8,damages are estimated to be at least USD$33.2 million.
As early as October 4, the National Hurricane Center (NHC) noted the potential for tropical cyclone formation from a tropical wave, which exited the west coast of Africa six days later. [2] [3] That day, the NHC designated the wave as Invest 94L, related to a low pressure area with disorganized convection, or thunderstorms. [4] Moving westward, the system became better organized as it moved through the Cape Verde islands, developing gale-force winds and an elongated circulation. The NHC assessed the potential for development as high as 50%, but downgraded the potential on October 12 due to unfavorable environmental conditions. [5] [6] For several days, the low continued westward across the Atlantic Ocean, producing only occasional thunderstorms due to dry air, and it opened up into a trough on October 16. [7] Two days later, the NHC assessed only a 10% chance for development, due to anticipated unfavorable conditions. At that time, the system was passing north of the Lesser Antilles and Puerto Rico. [8] However, the thunderstorms became better organized, [9] rapidly consolidated north of Hispaniola, [10] and a circulation reformed on October 19. [11] At 15:00 UTC that day, the NHC classified the system as Tropical Storm Oscar while located just east of the Turks and Caicos islands. [12]
Upon its designation by the NHC, Oscar had a small central dense overcast fueled by hot towers, surrounded by well-defined rainbands. The storm moved westward, steered by a ridge to its north. [12] At 18:00 UTC on October 19, the NHC upgraded Oscar to hurricane intensity, just three hours after beginning advisories. This was based on observations from the Hurricane Hunters, which observed a very small well-defined eye with a diameter of only 3.45 mi (5.55 km). [13] A dropsonde into the eye observed wind gusts of 94 mph (152 km/h). On that basis, the NHC estimated peak winds of 85 mph (140 km/h). At its peak, Oscar had hurricane-force winds extending only 5.75 mi (9.25 km) from the center, and gale-force winds 35 mi (55 km) from the center. [14] At this point, Oscar was a very small storm with traits similar to thunderstorm clusters. [15] Early on October 20, the center of Oscar passed very near Grand Turk Island, before making landfall on Inagua. [16] During the turning operation towards Cuba, the eye expanded to a diameter of around 20 mi (32 km), as Oscar's track shifted towards the west-southwest and reached its lowest pressure of 986 mbar. [17] [18] At 21:50 UTC on October 20, Oscar made a second landfall in eastern Cuba, near the city of Baracoa. [19]
After moving ashore eastern Cuba, Oscar quickly weakened into a tropical storm. [20] The circulation became disrupted over the mountainous terrain as its forward motion slowed. [21] A trough over the western Atlantic pulled Oscar northward, and the circulation emerged over water early on October 22. The storm was unable to regenerate due to stronger wind shear and dry air, and later that day Oscar dissipated near the Bahamas. [22] The remnants were then absorbed by a nearby extratropical cyclone, which then travelled northwards towards the Nova Scotia Peninsula, and made landfall on October 25 on the south coast of the peninsula and Newfoundland, with rainfall reaching up to 125 mm (4.9 in) predicted across some parts of Newfoundland. [23]
Philippe Papin of the NHC noted that Oscar "...kind of snuck up a little bit on us". [24] As the predecessor to Oscar made its way north of the Greater Antilles, models began to stop showing tropical development in their forecasts. [25]
Oscar was the smallest hurricane on record with a five-to-six-mile (8.0 to 9.7 km) wide hurricane-force wind field. [1] Due to Oscar's size, most satellites were unable to accurately measure its actual strength. [25] RADARSAT, a high-resolution Canadian satellites, showed that Oscar peaked around Category 2 or 3 strength prior to landfall. [25]
On the afternoon of October 19, the Government of The Bahamas issued a hurricane warning for the Turks and Caicos Islands and Southeastern Bahamas. [26] The Central Bahamas were later placed under tropical storm warning on October 21. [27] The Turks and Caicos Islands Airport Authority closed JAGS McCartney International Airport, Norman B. Saunders International Airport, and Leon Wilson Airport. [28] The Bahamian Disaster Risk Management (DRM) Authority activated its team on October 19. [29]
Matthew Town experienced winds from the core of Oscar. [15] On Grand Turk, where the capital of the Turks and Caicos Islands is located, Oscar knocked down some trees and removed the roofs of at least one house. However, as there was a low tide, the hurricane caused minimal impacts in the islands. [30] A shelter in Inagua housed 24 people. [31]
The DRM Authority sent food items to the southern islands after Oscar had left. [32]
The Government of Cuba issued a hurricane watch for the provinces of Guantánamo, Holguín, and Las Tunas on October 19. [26] Dissemination of information related to Oscar was impeded by a country-wide blackout. [33] Coordinators were also unable to communicate with one another without electricity. [34] More than 15,000 people were evacuated in the nation, with 9,000 being evacuated in Imías and 6,000 evacuated in San Antonio del Sur. [35] [36]
As Oscar neared Cuba, a station in Cape Maisí saw a peak gust of 103 km/h (64 mph). [37] Torrential downpours were recorded in Cuba, with preliminary reports in the province of Guantánamo stating that some places received more than 10 in (25 cm). [21] A station in Maisí saw 366 mm (14.4 in) or rainfall, while in Baracoa, 268 mm (10.6 in) was seen. [35] In Baracoa, waves produced by the hurricane breached the seawall, causing flooding along the city's coastline. [38] Oscar caused severe damage in eastern Guantánamo. [39] At least 2,282 homes were damaged, more than half of them with total roof collapses. [40] Severe flooding occurred in Baracoa, Imías, and Maisí. Dozens homes lost their roofs and many power lines were downed. [41] [42] The rainfall and winds led to landslides, which also slowed the fixing of the blackout. [43] In the Caujerí Valley, 200 hectares (2.0 km2) of tomatoes were destroyed. [44] 6,500 cans of coffee grains, along with numerous amounts of bananas and beans, were lost. The Cadena River was flooded. [45] The Pozo Azul Dam reached 86% capacity while the Los Asientos Dam met capacity. [46] The former saw false rumors spread online about a possible collapse. The Cuban Army denounced the rumors. [46] Salt flats owned by the Salinera Company received serious damage from Oscar. [44] Eight people were killed from the storm: [47] six in San Antonio and one in Imías. [48] [49] Officials estimate that they would need at least USD$33.2 million to support the recovery from the damage caused by Oscar. [50]
A ship was sent from Pajaritos, Veracruz, to Cuba, with 400,000 barrels of oil to alleviate the power crisis worsened by Oscar. [51]
Still recovering from Oscar, eastern Cuba was rattled by a 6.8-magnitude earthquake on November 10. [52]

The remnants of Oscar increased surf in the Northeastern United States coast. [53]
As the remnants of Oscar were forecasted to approach Ireland, Met Éireann issued weather warnings. [54]
Hurricane Debby caused minor damage in the Greater and Lesser Antilles in August 2000. The seventh tropical cyclone, fourth named storm, and second hurricane of the annual season, Debby developed from a tropical wave east of the Lesser Antilles on August 19. Favorable conditions allowed the depression to become Tropical Storm Debby early on August 20, and further strengthening into a hurricane occurred 24 hours later. Sustained winds peaked at 85 mph (137 km/h) on August 21. Debby made three landfalls on August 22, in Barbuda, Saint Barthélemy, and Virgin Gorda, before re-entering the Atlantic north of Puerto Rico. As Debby moved parallel to the north coast of Hispaniola late on August 23, it weakened back to a tropical storm. The storm tracked westward and weakened further, instead of approaching Florida and strengthening into a major hurricane. While south of eastern Cuba on August 24, Debby was downgraded to a tropical depression, six hours before completely dissipating.
Tropical Storm Chris was the fourth tropical storm of the 2006 Atlantic hurricane season. Forming on July 31 in the Atlantic Ocean east of the Leeward Islands from a tropical wave, Chris moved generally to the west-northwest, skirting the northern fringes of the Caribbean islands. Chris was a relatively short-lived storm, reaching a peak intensity with winds at 65 mph (105 km/h) on August 2, while positioned north of St. Martin. The storm gradually weakened before finally dissipating on August 5, near eastern Cuba. Overall impact was minimal, amounting to moderate amounts of rainfall throughout its path. No deaths were reported.
Hurricane Olga was the fifteenth named storm and ninth hurricane of the 2001 Atlantic hurricane season. It was notable as it was the largest tropical cyclone by diameter of gale-force winds on record in the Atlantic at the time. Hurricane Olga formed as a subtropical cyclone on November 24. After acquiring tropical characteristics later that day, Olga meandered westward, and eventually reached hurricane status on November 26. Olga peaked as a 90 mph (140 km/h) Category 1 hurricane before the storm turned southwestward and weakening back into a tropical storm. On November 30 it deteriorated further to a tropical depression, although it re-intensified two days later to tropical storm intensity. Olga then dissipated as a tropical cyclone on December 4 east of the Bahamas. Its damaging effects were limited to ships at sea. The cyclone's remnants produced heavy rainfall across the Bahamas and Florida. It was a relatively rare storm to exist in December, which is outside of the normal Atlantic hurricane season.
Tropical Storm Bonnie was a small and rather weak tropical storm that brought squally weather to the northern Caribbean Sea and Gulf Coast of the United States in July 2010. The third tropical cyclone and second named storm of the 2010 Atlantic hurricane season, Bonnie developed from a tropical wave over the Bahamas on July 22. It strengthened to a tropical storm while crossing the islands, and made landfall on the southeastern coast of Florida the following day. Inland, Bonnie weakened to a tropical depression before entering the Gulf of Mexico, where its surface circulation dissipated on July 24. The remnants of the storm moved ashore between Louisiana and Mississippi early on July 25, prompting severe thunderstorm and tornado warnings in the area.
Tropical Storm Beryl was the strongest off-season Atlantic tropical cyclone on record to make landfall in the United States. The second tropical cyclone of the 2012 Atlantic hurricane season, Beryl developed on May 26 from a low-pressure system offshore North Carolina. Initially subtropical, the storm slowly acquired tropical characteristics as it tracked across warmer sea surface temperatures and within an environment of decreasing vertical wind shear. Late on May 27, Beryl transitioned into a tropical cyclone less than 120 miles (190 km) from North Florida. Early the following day, the storm moved ashore near Jacksonville Beach, Florida, with peak winds of 65 mph (100 km/h). It quickly weakened to a tropical depression, dropping heavy rainfall while moving slowly across the southeastern United States. A cold front turned Beryl to the northeast, and the storm became extratropical on May 30.
Hurricane Bertha was an unusual tropical cyclone in early August 2014 that attained hurricane status, despite having a disheveled appearance and an abnormally high atmospheric pressure. The third tropical cyclone and second hurricane of the season, Bertha developed from a tropical wave south of Cape Verde was monitored first for possible tropical cyclogenesis on July 26. Over the following days, it slowly developed and acquired gale-force winds and enough convection to be designated as Tropical Storm Bertha early on August 1. A mostly disorganized cyclone, Bertha quickly moved across the Lesser Antilles, clipping the northern end of Martinique, later that day. During its trek across the eastern Caribbean Sea, its circulation became severely disrupted and it may have degenerated into a tropical wave. On August 3, it traversed the Mona Passage and moved over the Southeastern Bahamas where conditions favored development. Despite an overall ragged appearance on satellite imagery, data from Hurricane Hunters indicated it intensified to a hurricane on August 4; it acquired peak winds of 80 mph (130 km/h) that day. Turning north, and later northeast, Bertha soon weakened as it began to merge with an approaching trough to the west. This merger ultimately took place on August 6, at which time Bertha was declared extratropical well to the south of Nova Scotia. The remnant system raced eastward across the Atlantic and later struck the United Kingdom on August 10. Once over the North Sea, the storm stalled for a few days before resuming its eastward track. It was last noted around the Baltic Sea on August 16. And Shulia travelled though this to see Holli
Hurricane Joaquin was a powerful tropical cyclone that devastated several districts of The Bahamas and caused damage in the Turks and Caicos Islands, parts of the Greater Antilles, and Bermuda. It was also the strongest Atlantic hurricane of non-tropical origin recorded in the satellite era. The tenth named storm, third hurricane, and second major hurricane of the 2015 Atlantic hurricane season, Joaquin evolved from a non-tropical low to become a tropical depression on September 28, well southwest of Bermuda. Tempered by unfavorable wind shear, the depression drifted southwestward. After becoming a tropical storm the next day, Joaquin underwent rapid intensification, reaching hurricane status on September 30 and Category 4 major hurricane strength on October 1. Meandering over the southern Bahamas, Joaquin's eye passed near or over several islands. On October 3, the hurricane weakened somewhat and accelerated to the northeast. Abrupt re-intensification ensued later that day, and Joaquin acquired sustained winds of 155 mph (250 km/h), just short of Category 5 strength.
Hurricane Matthew was the first Category 5 Atlantic hurricane since Felix in 2007 and the southernmost Category 5 Atlantic hurricane on record. The system originated from a tropical wave that emerged off the west coast of Africa on September 22, and ultimately dissipated as an extratropical cyclone near Atlantic Canada on October 10. Late on September 29, it began a period of explosive intensification that brought it to Category 5 strength early on October 1. It weakened slightly and remained a Category 4 until its landfalls in Haiti and Cuba, afterwards it traversed through the Bahamas and paralleled the coast of Florida until making landfall in South Carolina as a Category 1 hurricane. Matthew later transitioned into a post-tropical cyclone on October 10.
The 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average activity in terms of number of named storms, but below-average activity in terms of major hurricanes, as 19 named storms, 8 hurricanes, and 2 major hurricanes formed in all. It also had a near-normal accumulated cyclone energy (ACE). The season officially began on May 15, 2021 in the Eastern Pacific Ocean, and on June 1, 2021, in the Central Pacific in the Northern Hemisphere. The season ended in both regions on November 30, 2021. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as illustrated by the formation of Tropical Storm Andres on May 9, which was the earliest forming tropical storm on record in the Eastern Pacific. Conversely, 2021 was the second consecutive season in which no tropical cyclones formed in the Central Pacific.
The 2022 Pacific hurricane season was a slightly above average hurricane season in the eastern North Pacific basin, with nineteen named storms, ten hurricanes, and four major hurricanes. Two of the storms crossed into the basin from the Atlantic. In the central North Pacific basin, no tropical cyclones formed. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central; both ended on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.
The 2024 Atlantic hurricane season was a very active and extremely destructive Atlantic hurricane season which became the second costliest on record, inflicting at least $220 billion in damages and 400 deaths overall, most of which was caused by four systems: Beryl, Debby, Helene, and Milton. The season produced 18 named storms, 11 hurricanes, and 5 major hurricanes; it was also the first since 2019 to feature multiple Category 5 hurricanes. Additionally, the season had the highest accumulated cyclone energy (ACE) rating since 2020, with a value of 161.6 units. The season officially began on June 1, and ended on November 30. These dates, adopted by convention, have historically described the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean.
The Bahama Archipelago, also known as the Lucayan Archipelago, is an archipelago comprising the Commonwealth of The Bahamas and the British Overseas Territory of the Turks and Caicos Islands. The archipelago is in the western North Atlantic Ocean, north of Cuba along with the other Antilles, and east and southeast of Florida. The archipelago has experienced the effects of at least 22 Atlantic hurricanes, or storms that were once tropical or subtropical cyclones, including 17 since 2000. The storms collectively killed 101 people.
The 2024 Pacific hurricane season was a below-average Pacific hurricane season. There were 15 tropical cyclones overall, of which all but 2 became named storms. Of the 13 named storms, 5 developed into hurricanes, of which 3 intensified into major hurricanes. The season officially began on May 15 in the eastern Pacific basin and on June 1 in the central Pacific ; both ended on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in these regions of the Pacific Ocean. For the third consecutive year, there were no pre-season tropical cyclones in either basin, and the season got off to the slowest start of any Pacific hurricane season on record in the satellite era, with the first eastern Pacific tropical storm, Aletta, not forming until July 4. The first, and only, central Pacific tropical storm, Hone, formed on August 22, becoming the first named storm to develop in the basin since 2019. The final system of the season, Tropical Depression Fourteen‑E, dissipated on November 7.
Tropical Storm Philippe was a weak and disorganized tropical cyclone which affected Central America, Cuba, and Florida during October 2017. The sixteenth named storm of the extremely-active 2017 Atlantic hurricane season, Philippe originated from the interaction of a tropical wave which exited the coast of West Africa on October 16, and the Central American Gyre on October 24. This formed a broad area of low pressure the next day, that later organized into a tropical depression at 12:00 UTC on October 28. The depression strengthened into Tropical Storm Philippe just six hours later, before making landfall west of the Bay of Pigs in Cuba just a few hours later. Philippe quickly degraded into a tropical depression inland, before dissipating at 0:00 UTC the following day. The remnants later formed into a new low pressure area off the coast of Florida before merging with a cold front, later that same day.
Hurricane Enrique was a Category 1 Pacific hurricane that brought heavy rainfall and flooding to much of western Mexico in late June 2021. The fifth named storm and first hurricane of the 2021 Pacific hurricane season, Enrique developed from a tropical wave the entered the Pacific Ocean off the coast of Nicaragua on June 22. In an environment conducive for intensification, the disturbance moved west-northwestward and developed into a tropical storm by 6:00 UTC on June 25, as it was already producing winds of 40 mph (65 km/h), and received the name Enrique. Enrique strengthened steadily within an environment of warm waters and low-to-moderate wind shear while continuing its northwestward motion. By 12:00 UTC on June 26, Enrique had intensified into a Category 1 hurricane as the storm turned more northwestward. Nearing the coast of Mexico, Enrique reached its peak intensity around 6:00 UTC the following day, with maximum sustained winds of 90 mph (150 km/h) and a minimum barometric pressure of 972 mbar (28.7 inHg). Enrique, passing closely offshore west-central Mexico, maintained its intensity for another 24 hours as it turned northward toward the Gulf of California. Turning back to the northwest on June 28, increasing wind shear and dry air caused the hurricane to weaken. Enrique dropped to tropical storm status at 18:00 UTC that day, and further weakened to a tropical depression on June 30 just to the northeast of Baja California. The depression was absorbed into a larger low pressure area to the southeast later that day.
Hurricane Sam was a powerful and long-lived tropical cyclone that threatened Bermuda, lasting from September 22 through October 7, 2021. It was the fifth longest-lasting intense Atlantic hurricane, as measured by accumulated cyclone energy, since reliable records began in 1966. Sam was the eighteenth named storm, seventh hurricane, and fourth major hurricane of the 2021 Atlantic hurricane season.
Tropical Storm Alex was a strong and fast moving tropical storm that caused flash flooding in western Cuba and South Florida while developing into the first named storm of the 2022 Atlantic hurricane season. Alex originated from a broad area of low pressure partially related to the remnants of Hurricane Agatha in the Eastern Pacific. The National Hurricane Center (NHC) initiated advisories on it as Potential Tropical Cyclone One over the eastern Yucatán Peninsula on June 2. Wind shear and dry air kept the system disorganized until after it crossed Florida two days later. Finally, on June 5, the system became sufficiently organized and was named Alex while located north of Grand Bahama Island. Later that same day, Alex's winds briefly strengthened to 70 mph (110 km/h). The storm brought rain and strong winds to Bermuda on June 6, before becoming a post-tropical cyclone that same day. Alex formed four days after the official start of the season, making the 2022 Atlantic hurricane season the first since 2014 not to have a pre-season named storm.
Hurricane Fiona was a large, powerful, and destructive tropical cyclone which was the most intense tropical or post-tropical cyclone to hit Canada on record. It was also the costliest cyclone to hit the country until this record was broken by Debby in 2024. It was the sixth named storm, third hurricane and first major hurricane of the 2022 Atlantic hurricane season.
Hurricane Franklin was a long-lived, erratic, and powerful tropical cyclone that brought tropical-storm force winds to parts of the Greater Antilles and Bermuda. The sixth named storm, second hurricane and first major hurricane of the 2023 Atlantic hurricane season, Franklin impacted Hispaniola as a tropical storm before strengthening into a high-end Category 4 hurricane several days later. Possessing a large wind field, the hurricane produced tropical storm force winds over Bermuda and soon became extratropical as it accelerated into the open northern Atlantic Ocean. The extratropical cyclone persisted for several more days before dissipating on September 10.
