The 2003 Atlantic hurricane season was a very active season with tropical cyclogenesis occurring 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. 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 2002 Atlantic hurricane season was a near-average Atlantic hurricane season. It officially started on June 1, 2002, and ended on November 30, dates which conventionally limit the period of each year when most tropical cyclones develop in the Atlantic Ocean. The season produced fourteen tropical cyclones, of which twelve developed into named storms; four became hurricanes, and two attained major hurricane status. While the season's first cyclone did not develop until July 14, activity quickly picked up: eight storms developed in the month of September. It ended early however, with no tropical storms forming after October 6—a rare occurrence caused partly by El Niño conditions. The most intense hurricane of the season was Hurricane Isidore with a minimum central pressure of 934 mbar, although Hurricane Lili attained higher winds and peaked at Category 4 whereas Isidore only reached Category 3. However, Lili had a minimum central pressure of 938 mbar.
Tropical Storm Ana was the first named storm of the 2003 Atlantic hurricane season. A pre-season storm, it developed initially as a subtropical cyclone from a non-tropical low on April 20 to the west of Bermuda. It tracked east-southeastward and organized, and on April 21 it transitioned into a tropical cyclone with peak winds of 60 mph (97 km/h). Tropical Storm Ana turned east-northeastward, steadily weakening due to wind shear and an approaching cold front, and on April 24 it became an extratropical cyclone. The storm brushed Bermuda with light rain, and its remnants produced precipitation in the Azores and the United Kingdom. Swells generated by the storm capsized a boat along the Florida coastline, causing two fatalities.
Hurricane Nate was an Atlantic hurricane that threatened Bermuda but remained at sea during early September 2005. The fourteenth named storm and seventh hurricane of the annual Atlantic hurricane season, Nate formed southwest of Bermuda on September 5 and initially moved very slowly to the northeast. Early forecasts suggested a possible threat to the island, but Nate passed well to its south as a Category 1 hurricane on September 8. After moving away from the island, the storm entered a region with cooler sea surface temperatures and unfavorable wind shear, causing it to weaken to a tropical storm before becoming extratropical on September 10. The extratropical remnant was later absorbed by a larger weather system.
Hurricane Lili was the first Atlantic hurricane to develop in December since Hurricane Alice in in 1954. The thirteenth and last tropical storm in the 1984 Atlantic hurricane season, Lili developed as a subtropical cyclone which originated from a frontal trough to the south of Bermuda on December 12. It tracked southeastward, then northward, over open water for more than a week, slowly attaining tropical characteristics and becoming a hurricane on December 20. Lili turned to the south and southwest, briefly threatening the northern Caribbean islands before weakening and dissipating near the coast of the Dominican Republic. The storm produced light rainfall but no damage.
Hurricane Gabrielle was a North Atlantic hurricane that caused flooding in both Florida and Newfoundland in September 2001. It developed in the Gulf of Mexico on the same day as the September 11 attacks; after the attacks, flights were canceled nationwide for two days, and when Gabrielle struck Florida on September 14, it caused a day of additional cancellations. The storm moved ashore with winds of 70 mph (110 km/h) near Venice, a city located south of the Tampa Bay area. The combination of the winds and heavy rainfall, which peaked at 15.1 in (380 mm) in Parrish, left 570,000 customers without power along the west coast and 126,000 customers without power on the east coast. The storm caused about $230 million (2001 USD) in damage in Florida. In the Gulf of Mexico, high waves contributed to two deaths, one of which was indirect; there was also a death due to flooding in Winter Haven.
Hurricane Kyle was the fifth-longest-lived Atlantic tropical or subtropical cyclone on record. The eleventh named storm and third hurricane of the 2002 Atlantic hurricane season, Kyle developed as a subtropical cyclone on September 20 to the east-southeast of Bermuda. Looping westward, it transitioned into a tropical cyclone and became a hurricane on September 25. For the next two weeks, Kyle tracked generally westward, oscillating in strength several times because of fluctuations in environmental conditions. On October 11, the cyclone turned northeastward and made landfalls near Charleston, South Carolina, and Long Beach, North Carolina, at tropical storm status. After lasting as a cyclone for 22 days, Kyle dissipated on October 12 as it was absorbed by an approaching cold front.
Hurricane Karen was a hurricane of non-tropical origin that formed in October of the 2001 Atlantic hurricane season. It developed out of the interaction between a cold front and an upper level trough on October 10 located to the south of Bermuda, and quickly strengthened as an extratropical storm. The storm passed near Bermuda on October 12, producing hurricane-force winds on the island. It then organized, becoming a subtropical cyclone on October 12 and a tropical cyclone on October 13. Karen strengthened to reach 80 mph (130 km/h) winds as a Category 1 hurricane on the Saffir-Simpson Hurricane Scale, and after weakening over cooler waters, it made landfall on Nova Scotia as a tropical storm. It quickly became extratropical.
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 Erin was the longest-lived hurricane in the 2001 Atlantic hurricane season. The sixth tropical depression, fifth tropical storm, and first hurricane of the season, Erin developed from a tropical wave on September 1. After strengthening to a 60 mph (97 km/h) tropical storm as it moved to the west-northwest, wind shear weakened Erin and caused it to degenerate into a remnant low on September 5. The remnants re-organized into a tropical depression the next day, and Erin strengthened into a hurricane on September 9 while moving northwestward. This was the latest date for the first hurricane of the season since Hurricane Diana on September 10, 1984. Erin quickly intensified and reached peak winds of 120 mph (190 km/h) later on September 9. At its closest approach, Erin passed 105 miles (169 km) east-northeast of Bermuda near peak intensity, and subsequently weakened as it turned to the east. A trough turned Erin to the northeast, and after passing just east of Cape Race, Newfoundland it became extratropical on September 15. The extratropical remnant continued northeastward and was absorbed into another extratropical storm near Greenland on September 17.
Hurricane Bertha caused minor damage in the United States, Bermuda, and Atlantic Canada in July and August 1990. The third tropical cyclone, second named storm, and first hurricane of the 1990 Atlantic hurricane season, Bertha developed from a frontal low pressure area offshore of North Carolina on July 24. Initially subtropical, it slowly acquired tropical characteristics while tracked southeast and then southwestward. By early on July 27, the cyclone was re-classified as a tropical depression. Following its transition, the depression intensified and was upgraded to Tropical Storm Bertha on July 28. The storm then curved northeastward and rapidly strengthened. Bertha became a hurricane early on July 29, though it weakened back to a tropical storm later that day. On the following day, Bertha re-intensified into a hurricane and peaked as an 80 mph (130 km/h) Category 1 hurricane on July 31.
Tropical Storm Chantal was a short-lived tropical storm that affected Bermuda in its formative stages and caused flooding and gusty winds in Newfoundland while extratropical. The third named storm of the 2007 Atlantic hurricane season, Chantal developed on July 31 from non-tropical origins between Bermuda and Cape Cod, and with favorable conditions, the storm rapidly attained peak winds of 50 mph (80 km/h). The storm accelerated northeastward over an area of progressively colder water temperatures, and after a decrease in convection the National Hurricane Center ceased issuing advisories as Chantal began undergoing extratropical transition early on August 1. Shortly thereafter, the extratropical remnant crossed over southeastern Newfoundland before tracking into the open waters of the north Atlantic Ocean. Prior to forming, the storm dropped moderate rainfall on Bermuda. Subsequent to becoming extratropical, the remnants of Chantal produced gusty winds and heavy precipitation across the Avalon Peninsula of Newfoundland, causing flooding and wind damage; insured damage totaled $25 million.
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.
Hurricane Florence attained Category 1 intensity on three separate occasions in mid-September 2000. The tenth tropical cyclone, sixth named storm, and third hurricane of the 2000 Atlantic hurricane season, Florence developed on September 10 from a cold front to the southwest of Bermuda. Initially a subtropical cyclone, it quickly organized, attaining hurricane status twice in a two-day period before weakening while remaining nearly stationary. Florence accelerated northeastward, reaching peak winds as a hurricane after passing near Bermuda. On September 17, the storm was absorbed by a larger extratropical cyclone. Hurricane Florence threatened Bermuda during its third time at hurricane intensity, bringing tropical storm force winds to the island but causing no reported damage. However, three deaths in North Carolina were blamed on rip currents triggered by the hurricane on September 12.
The 2014 Atlantic hurricane season was a below-average hurricane season in terms of named storms and major hurricanes, though average in terms of number of hurricanes overall. It produced nine tropical cyclones, eight of which became named storms; six storms became hurricanes and two intensified further into major hurricanes. The season officially began on June 1, and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin. The first storm of the season, Arthur, developed on July 1, while the final storm, Hanna, dissipated on October 28, about a month prior to the end of the season.
Tropical Storm Colin was a tropical cyclone that brought squally weather to Bermuda and caused extensive rip currents across the East Coast of the United States in August 2010. The fourth tropical cyclone and third named storm of the 2010 Atlantic hurricane season, Colin developed as a tropical depression from a low-pressure area in the central Atlantic on August 2. After forming, the storm initially strengthened gradually, attaining tropical storm status early on August 3. However, due to its acceleration to the west-northwest, Colin was unable to maintain a closed circulation and subsequently degenerated into a trough later that day. The National Hurricane Center noted the possibility of regeneration over subsequent days, and by August 5, Colin had once again become a tropical cyclone. Despite moderate wind shear impacting the system, Colin reached a peak intensity of 60 mph (97 km/h) on August 5. However, vertical wind shear prevented further intensification and eventually weakened the storm. By early on August 8, Colin had weakened to a tropical depression, and dissipated near Bermuda shortly after. Though it remained well offshore, Colin produced rough seas along the East Coast of the United States. At least 205 ocean rescues were made. In Bermuda, effects were generally minimal. Less than 1 inch (25 mm) of rain fell and winds remained below tropical storm force.
The 2019 Atlantic hurricane season was the fourth consecutive above-average and damaging season dating back to 2016. However, many storms were weak and short-lived, especially towards the end of the season. Six of those named storms achieved hurricane status, while three intensified into major hurricanes. Two storms became Category 5 hurricanes, marking the fourth consecutive season with at least one Category 5 hurricane, the third consecutive season to feature at least one storm making landfall at Category 5 intensity, and the seventh on record to have multiple tropical cyclones reaching Category 5 strength. The season officially began on June 1 and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the formation of Subtropical Storm Andrea on May 20, making this the fifth consecutive year in which a tropical or subtropical cyclone developed outside of the official season.
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 ten 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, continuing 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 hurricanes formed.
Hurricane Cristobal was a moderately strong Atlantic tropical cyclone that affected multiple landmasses from Puerto Rico to Iceland in late August and early September 2014. Slow to develop and inhibited by unfavorable wind shear for most of its duration, the storm formed on August 23 near the Caicos Islands from a long-tracked tropical wave. Moving generally northward, Cristobal gradually intensified despite a ragged appearance on satellite imagery, and passed midway between Bermuda and North Carolina on August 27. The next day, while accelerating northeast, Cristobal achieved its peak strength as a Category 1 hurricane. A colder environment transitioned Cristobal into an extratropical cyclone on August 29, but it retained much of its strength as it sped across the northern Atlantic and struck Iceland on September 1.
Hurricane Chris was a moderately strong tropical cyclone that affected the East Coast of the United States and Atlantic Canada in July 2018. The third tropical or subtropical cyclone, third named storm, and second hurricane of the 2018 Atlantic hurricane season, Chris originated from a frontal system that moved offshore the coast of the northeastern United States on June 29. The front evolved into a non-tropical low by July 3. After further organization, a tropical depression formed on July 6, several hundred miles south-southeast of Cape Hatteras, North Carolina. Two days later, the depression strengthened into a tropical storm and received the name Chris. Chris slowly strengthened as it drifted into warmer waters. These favorable conditions allowed Chris to rapidly intensify into a hurricane on July 10. The hurricane reached its peak intensity with winds of 105 mph (165 km/h) and a pressure of 969 mbar (28.61 inHg) at. This peak intensity was short-lived though, as Chris began to undergo extratropical transition. At 12:00 UTC on July 12, Chris became an extratropical cyclone well southeast of Newfoundland. The low continued northeastward over the Atlantic for the next few days, before weakening and finally dissipating southeast of Iceland on July 17.
