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 1979 Atlantic hurricane season was the first Atlantic hurricane season to include both male and female names on its list of tropical cyclone names. The season officially began on June 1, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was slightly below average, with nine systems reaching tropical storm intensity. The first system, an unnumbered tropical depression, developed north of Puerto Rico on June 9. Two days later, Tropical Depression One formed and produced severe flooding in Jamaica, with 40 deaths and about $27 million (1979 USD) in damage. Tropical Storm Ana caused minimal impact in the Lesser Antilles. Hurricane Bob spawned tornadoes and produced minor wind damage along the Gulf Coast of the United States, primarily in Louisiana, while the remnants caused flooding, especially in Indiana. Tropical Storm Claudette caused extensive flooding in Texas due to torrential rainfall, resulting in two deaths and about $750 million in damage.
The 1985 Atlantic hurricane season had six United States landfalling hurricanes, tied with 1886 and 2020 for the highest number on record. The season officially began on June 1 and lasted until November 30. It was an average season, with 11 named storms developing. This was partially attributed to a La Niña – a meteorological phenomenon that produces favorable conditions across the Atlantic basin, such as lower wind shear and higher sea surface temperatures. The first storm, Ana, developed on July 15 near Bermuda and caused minor effects in Canada while transitioning into an extratropical cyclone. Three other tropical cyclones – Claudette, Henri, and Isabel – did not significantly affect land. Claudette developed offshore of the Southeastern United States and brushed Bermuda and the Azores. Henri and Isabel were dissipating as they approached land. However, the precursor of the latter caused a severe flood in Puerto Rico that killed 180 people. Additionally, Tropical Storm Fabian and three tropical depressions did not have any known impact on land.
Tropical Storm Henri was a moderate tropical storm that formed in the 2003 Atlantic hurricane season. The eighth storm of the season, Henri was one of six tropical cyclones to hit the United States in the year. Henri formed from a tropical wave in the Gulf of Mexico in early September, and crossed over Florida as a tropical depression. Its remnants later moved into the Mid-Atlantic before dissipating completely.
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.
The 2021 Atlantic hurricane season was the third-most active Atlantic hurricane season on record, although many storms were weak and short-lived. With 21 named storms forming, it became the second season in a row and third overall in which the designated 21-name list of storm names was exhausted. Seven of those storms strengthened into a hurricane, four of which reached major hurricane intensity, which is slightly above-average. The season officially began on June 1 and ended on November 30. These dates historically describe the period in each year when most Atlantic tropical cyclones form. However, subtropical or tropical cyclogenesis is possible at any time of the year, as demonstrated by the development of Tropical Storm Ana on May 22, making this the seventh consecutive year in which a storm developed outside of the official season.
Hurricane Henri was a minimal category 1 hurricane that impacted the Northeastern United States. The eighth named storm and third hurricane of the 2021 Atlantic hurricane season, Henri developed from a well-defined low-pressure system north-northeast of Bermuda, becoming a tropical depression on August 16. Nearly a day later, the system strengthened into Tropical Storm Henri. Henri continued to move south, and later southwest before strengthening steadily, reaching its initial peak intensity with winds of 70 mph (110 km/h) and a pressure of 994 mbar (29.4 inHg) early on August 19. Soon after, strong wind shear weakened Henri slightly. Eventually, on August 21, Henri strengthened into a Category 1 hurricane, before weakening back to a tropical storm and making landfall in Westerly, Rhode Island, on August 22, making it the second tropical cyclone to make landfall in the U.S. state of Rhode Island during the season, seven weeks after Elsa. It proceeded to move west-northwestward, weakening into a tropical depression while slowing down later that day. On August 23, Henri degenerated into a remnant low over New England, before dissipating the next day over the Atlantic.
