Hurricane Michelle was the fifth costliest tropical cyclone in Cuban history and the strongest hurricane of the 2001 Atlantic hurricane season. The thirteenth named storm and seventh hurricane that year, Michelle developed from a tropical wave that had traversed into the western Caribbean Sea on October 29; the wave had initially moved off the coast of Africa 13 days prior. In its early developmental stages, the depression meandered over Nicaragua, later paralleling the Mosquito Coast before intensifying into tropical storm intensity on November 1; Michelle was upgraded to hurricane strength the following day. Shortly after, rapid intensification ensued within favorable conditions, with the storm's central barometric pressure dropping 51 mbar in 29 hours. After a slight fluctuation in strength, Michelle reached its peak intensity as a Category 4 hurricane with winds of 140 mph (230 km/h) and a minimum pressure of 933 mbar. This tied Michelle with 1999's Lenny as the fourth most powerful November hurricane on record in the Atlantic Basin, behind only the 1932 Cuba hurricane and 2020 Hurricanes Iota and Eta. At roughly the same time, the hurricane began to accelerate northeastward; this brought the intense hurricane to a Cuban landfall within the Bay of Pigs later that day. Crossing over the island, Michelle was weakened significantly, and was only a Category 1 hurricane upon reentry into the Atlantic Ocean. The hurricane later transitioned into an extratropical cyclone over The Bahamas on November 5, before being absorbed by a cold front the following day.
The 1981 Atlantic hurricane season featured direct or indirect impacts from nearly all of its 12 tropical or subtropical storms. Overall, the season was fairly active, with 22 tropical depressions, 12 of which became named storms. 7 of those reached hurricane status and a further 3 intensified into major hurricanes. The season officially began on June 1, 1981, and lasted until November 30, 1981. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, tropical cyclogenesis can occur before these dates, as demonstrated with the development of two tropical depressions in April and Tropical Storm Arlene in May. At least one tropical cyclone formed in each month between April and November, with the final system, Subtropical Storm Three, becoming extratropical on November 17, 1981.
Hurricane Ivan was a large, long-lived, and devastating tropical cyclone that caused widespread damage in the Caribbean and United States. The ninth named storm the sixth hurricane and the fourth major hurricane of the active 2004 Atlantic hurricane season, Ivan formed in early September, and reached Category 5 strength on the Saffir–Simpson Hurricane Scale (SSHS). Ivan caused catastrophic damage in Grenada as a strong Category 3 storm, heavy damage in Jamaica as a strong Category 4 storm, and then severe damage in Grand Cayman, Cayman Islands, and the western tip of Cuba as a Category 5 hurricane. After peaking in strength, the hurricane moved north-northwest across the Gulf of Mexico to strike Pensacola/Milton, Florida and Alabama as a strong Category 3 storm, causing significant damage. Ivan dropped heavy rain on the Southeastern United States as it progressed northeastward and eastward through the Eastern United States, becoming an extratropical cyclone on September 18. The remnant low of the storm moved into the western subtropical Atlantic and regenerated into a tropical cyclone on September 22, which then moved across Florida and the Gulf of Mexico, and then into Louisiana and Texas, causing minimal damage. Ivan degenerated into a remnant low on September 24, before dissipating on the next day.
The 1951 Atlantic hurricane season was the first hurricane season in which tropical cyclones were officially named by the United States Weather Bureau. The season officially started on June 15, when the United States Weather Bureau began its daily monitoring for tropical cyclone activity; the season officially ended on November 15. It was the first year since 1937 in which no hurricanes made landfall on the United States; as Hurricane How was the only tropical storm to hit the nation, the season had the least tropical cyclone damage in the United States since the 1939 season. As in the 1950 season, names from the Joint Army/Navy Phonetic Alphabet were used to name storms this season.
The 1944 Atlantic hurricane season featured the first instance of upper-tropospheric observations from radiosonde – a telemetry device used to record weather data in the atmosphere – being incorporated into tropical cyclone track forecasting for a fully developed hurricane. The season officially began on June 15, 1944, and ended on November 15, 1944. These dates describe the period of each year when most tropical cyclones form in the Atlantic basin. The season's first cyclone developed on July 13, while the final system became an extratropical cyclone by November 13. The season was fairly active season, with 14 tropical storms, 8 hurricanes, and 3 major hurricanes. In real-time, forecasters at the Weather Bureau tracked eleven tropical storms, but later analysis uncovered evidence of three previously unclassified tropical storms.
The 1933 Atlantic hurricane season is the most active Atlantic hurricane season on record in terms of accumulated Cyclone Energy (ACE), with a total of 259. It also set a record for nameable tropical storms in a single season, 20, which stood until 2005, when there were 28 storms. The season ran for six months of 1933, with tropical cyclone development occurring as early as May and as late as November. A system was active for all but 13 days from June 28 to October 7.
The 1939 Atlantic hurricane season was the least active since 1930. The season had below normal activity, with only six tropical storms, of which three became hurricanes and one became a major hurricane, equivalent to Category 3 status or higher on the modern-day Saffir–Simpson scale. The first tropical cyclone formed on June 12, and the last dissipated on November 6. These dates are within the period of each year when most tropical cyclones form in the Atlantic basin.
The 1938 Atlantic hurricane season produced fifteen tropical cyclones, of which nine strengthened into tropical storms. Four storms intensified into hurricanes. Two of those four became major hurricanes, the equivalent of a Category 3 or greater storm on the modern day Saffir–Simpson scale. The hurricane season officially began on June 16 and ended on November 15. In 2012, as part of the Atlantic hurricane reanalysis project, meteorologists identified a previously undocumented January hurricane and September tropical storm while fine-tuning the meteorological histories of several others. However, given scant observations from ships and weather stations, significant uncertainty of tropical cyclone tracks, intensity, and duration remains, particularly for those storms that stayed at sea.
The 1932 Atlantic hurricane season featured several powerful storms, including the Cuba hurricane, which remains the deadliest tropical cyclone in the history of Cuba and among the most intense to strike the island nation. It was a relatively active season, with fifteen known storms, six hurricanes, and four major hurricanes. However, tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. The Atlantic hurricane reanalysis project discovered four new tropical cyclones, all of which were tropical storms, that occurred during the year. Two storms attained Category 5 intensity, the first known occurrence in which multiple Category 5 hurricanes formed in the same year. The season's first cyclone developed on May 5, while the last remaining system transitioned into an extratropical cyclone by November 13.
The 1915 Atlantic hurricane season was an active Atlantic hurricane season in which six tropical storms developed. The first storm, which remained a tropical depression, appeared on April 29 near the Bahamas, while the final system, also a tropical depression, was absorbed by an extratropical cyclone well south of Newfoundland on October 22. Of the six tropical storms, five intensified into a hurricane, of which three further strengthened into a major hurricane. Four of the hurricanes made landfall in the United States. The early 20th century lacked modern forecasting and documentation, and thus, the hurricane database from these years may be incomplete.
The 1912 Atlantic hurricane season was an average hurricane season that featured the first recorded November major hurricane. There were eleven tropical cyclones, seven of which became tropical storms; four of those strengthened into hurricanes, and one reached major hurricane intensity. The season's first cyclone developed on April 4, while the final dissipated on November 21. The season's most intense and most devastating tropical cyclone was the final storm, known as the Jamaica hurricane. It produced heavy rainfall on Jamaica, leading to at least 100 fatalities and about $1.5 million (1912 USD) in damage. The storm was also blamed for five deaths in Cuba.
The 1890 Atlantic hurricane season was among the least active Atlantic hurricane seasons on record. The first tropical cyclone of the season was initially observed on May 27 and the last storm, Hurricane Four, dissipated over Central America on November 1. These dates fall within the period with the most tropical cyclone activity in the Atlantic. The first storm moved slowly north-northwestward, bringing heavy rains and extensive flooding to Cuba, which caused at least three fatalities and at least $1 million (1890 USD) in damage. It dissipated in the Gulf of Mexico on May 29. Tropical cyclogenesis went dormant for nearly two and a half months, until another system was observed near the Windward Islands on August 18. It traversed the Caribbean Sea and Gulf of Mexico, grazing the Yucatan Peninsula and making landfall in Louisiana before dissipating on August 28. Impact from the storm was minimal.
The 1887 Atlantic hurricane season was the most active Atlantic hurricane season on record at the time in terms of the number of known tropical storms that had formed, with 19. This total has since been equaled or surpassed multiple times. The 1887 season featured five off-season storms, with tropical activity occurring as early as May, and as late as December. Eleven of the season's storms attained hurricane status, while two of those became major hurricanes. It is also worthy of note that the volume of recorded activity was documented largely without the benefit of modern technology. Consequently, tropical cyclones during this era that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Thus, historical data on tropical cyclones from this period may not be comprehensive, with an undercount bias of zero to four per year between 1886 and 1910 estimated. The first system was initially observed on May 15 near Bermuda, while the final storm dissipated on December 12 over Costa Rica.
Hurricane Katrina was a late-forming tropical cyclone that impacted portions of the Greater Antilles and Bahamas in November 1981. The twenty-first tropical cyclone, eleventh named storm, and seventh hurricane of the 1981 Atlantic hurricane season, Katrina developed from an area of cloudiness in the western Caribbean Sea early on November 3. The initial tropical depression deepened slowly, and was upgraded to Tropical Storm Katrina on November 5. About six hours later, Katrina peaked with sustained winds of 85 mph (140 km/h). The storm made landfall along the south coast of Camagüey Province in Cuba early on November 6. Katrina quickly weakened to a tropical storm, before emerging into the Atlantic Ocean hours later. The system then accelerated northeastward and crossed the Bahamas late on November 6. Katrina dissipated late on November 7, shortly before merging with a frontal system.
The 1932 Cuba hurricane, known also as the Hurricane of Santa Cruz del Sur or the 1932 Camagüey hurricane, was the deadliest and one of the most intense tropical cyclones on record to have made landfall in Cuba. It is the only Category 5 Atlantic hurricane ever recorded in November. The cyclone had a path through the Caribbean Sea atypical to most hurricanes developing late in the Atlantic hurricane season. The storm's strong winds, storm surge, and rain devastated an extensive portion of central and eastern Cuba, where the storm was considered the worst natural disaster of the 20th century. Though the effects from the hurricane were concentrated primarily on Cuba, significant effects were also felt in the Cayman Islands and the Bahamas, with lesser effects felt elsewhere.
Hurricane Paloma was a strong late-season Atlantic hurricane that set several records for its intensity and formation. It was the sixteenth tropical storm, eighth hurricane and fifth major hurricane of the 2008 Atlantic hurricane season. Paloma was, at the time, the third most powerful November hurricane on record in the Atlantic Basin, behind only the 1932 Cuba hurricane, 2020's hurricanes Iota and Eta, and a tie of 1999's Hurricane Lenny, and 2001's Hurricane Michelle. Paloma also marked the first time that at least one major hurricane formed in every month of the hurricane season from July to November, with only June not having a major hurricane in the season.
From September 8 to 14, 2004, Hurricane Ivan moved through the Caribbean Sea, affecting all of the Greater Antilles. Reaching peak winds of 165 mph (266 km/h), Ivan attained Category 5 strength on the Saffir-Simpson Hurricane Scale, the strongest possible category, on three times in the Caribbean. It first lashed the southern coasts of Puerto Rico and Hispaniola with high waves, killing five people in the Dominican Republic and Haiti; in the latter country, two others drowned due to storm flooding. The effects in Jamaica were among the worst from a tropical cyclone in the island's recorded history. The storm caused severe damage which left 18,000 people homeless. An estimated 17 people on the island were killed by Ivan.
Hurricane Grace was the strongest tropical cyclone to make landfall in the Mexican state of Veracruz. Grace impacted much of the Leeward Islands and Greater Antilles as a tropical storm, before causing more substantial impacts in the Yucatán Peninsula and Veracruz as a hurricane. It was the seventh named storm, second hurricane, and first major hurricane of the 2021 Atlantic hurricane season. Originating from a tropical wave in the Main Development Region, the primitive system tracked west-northwest across the Atlantic Ocean towards the Antilles, becoming a tropical depression on August 14. It strengthened into Tropical Storm Grace later the same day, but weakened back to a depression due to an unfavorable environment. After moving near Haiti as a tropical depression, it strengthened back to a tropical storm and became a hurricane on August 18, reaching an initial peak intensity with maximum sustained winds of 80 mph (130 km/h) and a pressure of 986 mbar (29.12 inHg). It weakened back to a tropical storm after its landfall in the Yucatán Peninsula and emerged into the Bay of Campeche, entering a very favorable environment for intensification hours later. Grace then rapidly intensified into a Category 3 hurricane with winds of 120 mph (190 km/h) in about 24 hours. The storm made its final landfall in the state of Veracruz at peak intensity and quickly degenerated into a remnant low over mainland Mexico on August 21; however, its remnants later regenerated into Tropical Storm Marty in the Eastern Pacific on August 23.
Hurricane Rafael was the strongest November tropical cyclone in the Gulf of Mexico on record, tied with 1985's Hurricane Kate. The seventeenth named storm, eleventh hurricane, and fifth major hurricane of the 2024 Atlantic hurricane season, Rafael formed on November 4, 2024 from an area of low-pressure spawned by a Central American gyre. Steady organization occurred throughout the next two days, with Rafael becoming a hurricane early on November 6, as it moved northwest towards Cuba. Favorable conditions enabled the cyclone to rapidly intensify, becoming a Category 3 major hurricane later that day before making landfall in Cuba. Then, after weakening some while over land, it entered the Gulf of Mexico and re-intensified to a major hurricane once again at peak intensity early on November 8. Hostile conditions caused the hurricane to rapidly weaken afterwards, falling below hurricane intensity later that day, eventually degenerating into a remnant low on November 10. The circulation opened up into a trough the next day.
