Hurricane Hortense was the first tropical cyclone to make landfall in Guadeloupe and Puerto Rico since Hurricane Hugo in 1989, and the second most intense hurricane during the 1996 Atlantic hurricane season. The eighth tropical cyclone, eighth named storm, and sixth hurricane of the season. Hortense developed on September 3 from a tropical wave in the central Atlantic Ocean. Initially a tropical depression, it headed westward without significant strengthening for four days due to unfavorable upper-level winds. While nearing the Lesser Antilles upper-level winds decreased, allowing the depression to become Tropical Storm Hortense on September 7. Hortense crossed Guadeloupe on September 8 and entered the Caribbean Sea. By on the following day, it was upgraded to a hurricane while curving northwestward. Hortense made landfall in Puerto Rico on September 9 and brushed the Dominican Republic shortly thereafter. After re-entering the Atlantic, Hortense began to substantially strengthen and peaked as a 140 mph (220 km/h) Category 4 hurricane early on September 13. Thereafter, the storm steadily weakened as it tracked rapidly north-northeastward. Early on September 15, Hortense made landfall in Nova Scotia as a minimal Category 1 hurricane. It quickly weakened further to a tropical storm before re-entering the Atlantic to the south of Newfoundland. Late on September 15, Hortense transitioned into an extratropical cyclone and subsequently merged with a frontal system about 24 hours later.
The 1995 Atlantic hurricane season was an extremely active Atlantic hurricane season, and is considered to be the start of an ongoing era of high-activity tropical cyclone formation. The season produced twenty-one tropical cyclones, nineteen named storms, as well as eleven hurricanes and five major hurricanes. The season officially began on June 1 and ended on November 30, dates which conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The first tropical cyclone, Hurricane Allison, developed on June 2, while the season's final storm, Hurricane Tanya, transitioned into an extratropical cyclone on November 1. The very active Atlantic hurricane activity in 1995 was caused by La Niña conditions, which also influenced an inactive Pacific hurricane season.
Hurricane Danielle was a long-lived Cape Verde hurricane in late August and early September 1998. The fourth named storm and second hurricane of the annual hurricane season, Danielle originated from a tropical wave that emerged off the western coast of Africa on August 21. Tracking generally west-northwestward, the disturbance was initially disorganized; under favorable atmospheric conditions, shower and thunderstorm activity began to consolidate around a low-pressure center. Following a series of satellite intensity estimates, the system was upgraded to Tropical Depression Four during the pre-dawn hours of August 24, and further to Tropical Storm Danielle that afternoon. Moving around the southern periphery of the Azores High located in the northeastern Atlantic, quick intensification to hurricane status occurred early on August 25. By 0600 UTC the following day, Danielle reached an initial peak intensity of 105 mph (169 km/h), a Category 2 hurricane. Increased wind shear from a nearby trough encroached on further development later that day, and subsequently led to slight weakening. By 1200 UTC on August 27, despite continued unfavorable conditions, Danielle reached a second peak intensity equal to the first. Weakening once ensued late on August 27 in addition to the days following, and Danielle was a low-end Category 1 hurricane by August 31 as its forward speed slowed.
The 2003 Atlantic hurricane season was a highly active Atlantic hurricane season with tropical activity before and after the official bounds of the season—the first such occurrence since the 1970 season. The season produced 21 tropical cyclones, of which 16 developed into named storms; seven of those attained hurricane status, of which three reached major hurricane status. With sixteen storms, the season was tied for the fifth-most active Atlantic hurricane season on record, although it has since dropped down to become the seventh most active season. The strongest hurricane of the season was Hurricane Isabel, which reached Category 5 status on the Saffir–Simpson hurricane scale northeast of the Lesser Antilles; Isabel later struck North Carolina as a Category 2 hurricane, causing $3.6 billion in damage and a total of 51 deaths across the Mid-Atlantic region of the United States.
The 2000 Atlantic hurricane season was a fairly active hurricane season, but featured the latest first named storm in a hurricane season since 1992. The hurricane season officially began on June 1, and ended on November 30. It was slightly above average due to a La Niña weather pattern although most of the storms were weak. It was also the only Season to Include 2 storms in Ireland. The first cyclone, Tropical Depression One, developed in the southern Gulf of Mexico on June 7 and dissipated after an uneventful duration. However, it would be almost two months before the first named storm, Alberto, formed near Cape Verde; Alberto also dissipated with no effects on land. Several other tropical cyclones—Tropical Depression Two, Tropical Depression Four, Chris, Ernesto, Nadine, and an unnamed subtropical storm—did not impact land. Five additional storms—Tropical Depression Nine, Florence, Isaac, Joyce, and Leslie—minimally affected land areas.
Hurricane Marilyn was the most powerful hurricane to strike the Virgin Islands since Hurricane Hugo of 1989, and the third such tropical cyclone in roughly a two-week time span to strike or impact the Leeward Islands, the others being Hurricane Iris and the much more powerful and destructive Hurricane Luis. The thirteenth named storm, seventh hurricane and third major hurricane of the extremely active 1995 Atlantic hurricane season, Marilyn formed on September 12 as a tropical depression from a tropical wave that moved off the coast of Africa on September 7. After formation, the storm quickly became a tropical storm, and steadily intensified into a hurricane by the time it struck the Lesser Antilles on September 14 at Category 1 strength. Entering the northeastern Caribbean Sea, rapid intensification ensued and it peaked on September 16 north of Puerto Rico as a Category 3 hurricane shortly after it had impacted the U.S. Virgin Islands. A Hurricane Hunter reconnaissance flight reported hail, which is unusual for tropical cyclones. After heading north past Bermuda, Marilyn weakened and became extratropical on September 22. The remnant circulation wandered the Atlantic Ocean from September 23 – October 1, just south of Nova Scotia.
Hurricane Jose was the fourteenth tropical cyclone, tenth named storm, and seventh hurricane of the annual season that caused moderate damage in the Lesser Antilles in October 1999. Jose developed from a tropical wave several hundred miles east of the Windward Islands on October 17. The depression intensified and was subsequently upgraded to Tropical Storm Jose on October 18. The storm tracked northwestward and was upgraded to a hurricane the following day as it approached the northern Leeward Islands. Jose briefly peaked as a Category 2 hurricane with winds of 100 mph (160 km/h) on October 20. However, wind shear weakened the storm back to a Category 1 hurricane before it struck Antigua. Further deterioration occurred and Jose weakened to a tropical storm before landfall in Tortola on October 21. While located north of Puerto Rico on October 22, the storm turned northward, shortly before curving north-northeastward. Wind shear decreased, allowing Jose to re-intensify into a hurricane while passing east of Bermuda on October 24. However, on the following day, wind shear increased again, while sea surface temperatures decreased, causing Jose to weaken and quickly transition into an extratropical cyclone.
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 Dean was a strong tropical storm that affected at least twelve islands along its path from the tropical Atlantic Ocean to east of Atlantic Canada in August 2001. Dean developed from a tropical wave on August 22 over the Lesser Antilles, and was initially predicted to intensify further to reach hurricane status. However, strong wind shear quickly weakened Dean to cause it to dissipate on August 23. The remnants turned northward, and redeveloped on August 26 to the north of Bermuda. Located over warm waters and in an area of favorable conditions, Dean steadily strengthened while moving to the northeast, and peaked just below hurricane status on August 27 about 465 miles (748 km) southwest of Newfoundland. The storm subsequently weakened over cooler waters, and became extratropical on August 28.
Hurricane Dean was a strong tropical cyclone that brought minor effects the United States and Atlantic Canada offshore in early August 1989. The fourth named storm and second hurricane of the 1989 Atlantic hurricane season, Dean formed on July 31 and reached tropical storm status the following day east of the Leeward Islands. Dean brushed the northern Leeward Islands as a Category 1 hurricane on the Saffir–Simpson Hurricane Scale, bringing light rain but producing no damage, before turning northward and striking Bermuda as a Category 2 hurricane. It continued northward before making landfall in southeastern Newfoundland.
Hurricane Kyle was a Category 1 hurricane that caused heavy rain and flooding in Puerto Rico in its formative stage and brought hurricane-force winds to Nova Scotia while extratropical. The eleventh tropical storm and sixth hurricane of the 2008 Atlantic hurricane season, Kyle formed from a strong tropical disturbance that tracked across the northeastern Caribbean Sea in the third week of September. As a low pressure area, it moved slowly across Puerto Rico and Hispaniola, dumping torrential rains across those islands.
The 2011 Atlantic hurricane season was the second in a group of three very active Atlantic hurricane seasons, each with 19 named storms. The above-average activity was mostly due to a La Niña that persisted during the previous year. Of the season's 19 tropical storms, only seven strengthened into hurricanes, and only four of those became major hurricanes: Irene, Katia, Ophelia, and Rina. The season officially began on June 1 and ended on November 30, dates which conventionally delimit the period during each year in which most tropical cyclones develop in the Atlantic Ocean. However, the first tropical storm of the season, Arlene, did not develop until nearly a month later. The final system, Tropical Storm Sean, dissipated over the open Atlantic on November 11.
Tropical Storm Erika was a short-lived tropical cyclone that brought minor impacts to the Lesser Antilles. The fifth named storm of the 2009 Atlantic hurricane season, Erika originated out of a tropical wave on September 1 near the Lesser Antilles. Although it was a disorganized system, it was immediately declared a tropical storm, rather than a tropical depression. Later that day, the system reached its peak intensity with winds of 50 mph (85 km/h) and a barometric pressure of 1004 mbar. Increased wind shear caused the storm to weaken shortly thereafter, with Erika barely maintaining tropical storm-status by September 2. Later that day, the storm passed over the island of Guadeloupe and entered the Caribbean Sea. On September 3, Erika weakened to a tropical depression as the low pressure center became fully displaced from convective activity. Later that day, the system degenerated into a remnant low before dissipating near Puerto Rico on September 4.
The 2009 Atlantic hurricane season was a below-average Atlantic hurricane season that produced eleven tropical cyclones, nine named storms, three hurricanes, and two major hurricanes. It officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's first tropical cyclone, Tropical Depression One, developed on May 28, while the final storm, Hurricane Ida, dissipated on November 10. The most intense hurricane, Bill, was a powerful Cape Verde-type hurricane that affected areas from the Leeward Islands to Newfoundland. The season featured the lowest number of tropical cyclones since the 1997 season, and only one system, Claudette, made landfall in the United States. Forming from the interaction of a tropical wave and an upper-level low, Claudette made landfall on the Florida Panhandle with maximum sustained winds of 45 mph (70 km/h) before quickly dissipating over Alabama. The storm killed two people and caused $228,000 in damage.
Hurricane Igor was a very large Cape Verde hurricane and the most destructive tropical cyclone on record to strike the Canadian island of Newfoundland. It originated from a broad area of low pressure that moved off the western coast of Africa on September 6, 2010. Tracking slowly westward, it developed into a tropical depression on September 8 and strengthened into a tropical storm shortly thereafter. Higher wind shear temporarily halted intensification over the following days. On September 12, however, explosive intensification took place, and Igor reached Category 4 status on the Saffir–Simpson hurricane wind scale. By this time, Igor had already begun a prolonged turn around the western periphery of the subtropical ridge. After becoming the strongest cyclone of the season, with maximum sustained winds of 155 mph (249 km/h), it began to enter an area for continued strengthening. Igor gradually weakened before brushing Bermuda as a minimal hurricane on September 20. After turning northeastward, the system began an extratropical transition, which it completed shortly after striking southern Newfoundland. The remnants of Igor were later absorbed by another extratropical cyclone over the Labrador Sea on September 23.
Hurricane Ophelia was the most intense hurricane of the 2011 Atlantic hurricane season. The seventeenth tropical cyclone, sixteenth tropical storm, fifth hurricane, and third major hurricane, Ophelia originated in a tropical wave in the central Atlantic, forming approximately midway between the Cape Verde Islands and the Lesser Antilles on September 17. Tracking generally west-northwestward, Ophelia was upgraded to a tropical storm on September 21, and reached an initial peak of 65 mph (105 km/h) on September 22. As the storm entered a region of higher wind shear it began to weaken, and was subsequently downgraded to a remnant low on September 25. The following day, however, the remnants of the system began to reorganize as wind shear lessened, and on September 27, the National Hurricane Center once again began advisories on the system. Moving northward, Ophelia regained tropical storm status early on September 28, and rapidly deepened to attain its peak intensity with maximum sustained winds of 140 mph (230 km/h) several days later. The system weakened as it entered cooler sea surface temperatures and began a gradual transition to an extratropical cyclone, a process it completed by October 3.
Hurricane Leslie was an Atlantic tropical cyclone that caused minor damage in Bermuda and Atlantic Canada in September 2012. The twelfth tropical cyclone of the annual hurricane season, Leslie developed from a tropical wave located nearly 1,500 miles (2,400 km) east of the Leeward Islands on August 30. About twelve hours later, it strengthened into Tropical Storm Leslie. Tracking steadily west-northwestward, it slowly intensified due to only marginally favorable conditions. By September 2, the storm curved north-northwestward while located north of the Leeward Islands. Thereafter, a blocking pattern over Atlantic Canada caused Leslie to drift for four days. Late on September 5, Leslie was upgraded to a Category 1 hurricane. However, due to its slow movement, the storm causing upwelling, which decreased sea surface temperatures (SST's), weakening Leslie back to a tropical storm on September 7.
Hurricane Rafael produced minor damage in the northeastern Caribbean Sea in mid-October 2012. The seventeenth named storm and ninth hurricane of the 2012 hurricane season, Rafael originated from a tropical wave roughly 230 mi (370 km) south-southeast of Saint Croix on October 12; because the system already contained tropical storm-force winds, it skipped tropical depression status. Though initially disorganized due to moderate wind shear, a subsequent decrease allowed for shower and thunderstorm activity to develop in earnest by October 14. While moving north-northwestward the following morning, Rafael intensified into a Category 1 hurricane. A cold front off the East Coast of the United States caused the system to turn northward and eventually northeastward by October 16, at which time Rafael attained its peak intensity with maximum sustained winds of 90 mph (150 km/h). As the cyclone entered a more stable atmosphere and tracked across increasingly cooler sea surface temperatures, it began extratropical transition, a process the system completed by the following afternoon. However, Rafael's extratropical remnant persisted for another nine days, with the storm looping around a larger extratropical low over the north-central Atlantic, before turning southeastward and then eastward. Rafael's remnant later made landfall on Portugal on October 26, before dissipating later that day.
The 2020 Atlantic hurricane season was the most active Atlantic hurricane season on record, in terms of number of systems. It featured a total of 31 tropical or subtropical cyclones, with all but one cyclone becoming a named storm. Of the 30 named storms, 14 developed into hurricanes, and a record-tying seven further intensified into major hurricanes. It was the second and final season to use the Greek letter storm naming system, the first being 2005, the previous record. Of the 30 named storms, 11 of them made landfall in the contiguous United States, breaking the record of nine set in 1916. During the season, 27 tropical storms established a new record for earliest formation date by storm number. This season also featured a record 10 tropical cyclones that underwent rapid intensification, tying it with 1995, as well as tying the record for most Category 4 hurricanes in a singular season in the Atlantic Basin. This unprecedented activity was fueled by a La Niña that developed in the summer months of 2020 as it did, continue a stretch of above-average seasonal activity that began in 2016. Despite the record-high activity, this was the first season since 2015 in which no Category 5 hurricane formed.
Hurricane Fiona was a large, powerful, and destructive Category 4 Atlantic hurricane which was the costliest and most intense tropical or post-tropical cyclone to hit Canada on record. It was the sixth named storm, third hurricane and first major hurricane of the 2022 Atlantic hurricane season.
