The 2021 Atlantic hurricane season was the third most active Atlantic hurricane season on record with 21 named storms, and the sixth consecutive year in which there was above-average tropical cyclone activity[nb 1][2] The season officially began on June 1, 2021, and ended on November 30, 2021. These dates, adopted by convention, historically describe the period in each year when most Northern Atlantic tropical cyclones form.[3] However, tropical cyclone formation is possible at any time of the year, as was the case this season, when Tropical Storm Ana formed on May 22. The season's final system, Tropical Storm Wanda, dissipated on November 7. Of the season's 21 named storms, seven became hurricanes, and four further intensified into major hurricanes.[nb 2][5] The season's most devastating storm was Hurricane Ida. It made landfall in Louisiana with maximum sustained winds of 150 mph (240 km/h), destroying coastal communities in its path; parts of the New Orleans metropolitan area were left without power for several weeks.[6] The storm caused an estimated $75 billion (2021 USD) in damages in the U.S. and it was responsible for 87 deaths.[7] Over half of those deaths occurred in New York and New Jersey, as the hurricane's remnants brought rains that triggered widespread flooding throughout that region.[6] Additionally, heavy rains caused widespread flooding and landslides across Venezuela as Ida's precursor tropical wave passed though the southeastern Caribbean Sea, resulting in at least 20 deaths.[8] In April 2022, the name Ida was retired from reuse in the North Atlantic by the World Meteorological Organization due to the extraordinary amount of damage and number of fatalities it caused.[9]

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not initially warned upon, has been included.
By convention, meteorologists use one time zone when issuing forecasts and making observations: Coordinated Universal Time (UTC), and also use the 24-hour clock (where 00:00 = midnight UTC).[10] The National Hurricane Center uses both UTC and the time zone where the center of the tropical cyclone is currently located. The time zones utilized (east to west) are: Greenwich, Cape Verde, Atlantic, Eastern, and Central.[11] In this timeline, all information is listed by UTC first, with the respective regional time zone included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (knots, miles, or kilometers), following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury.

Notes edit
- ^ An average Atlantic hurricane season, as defined by the National Oceanic and Atmospheric Administration, has 12 tropical storms, six hurricanes and two major hurricanes.[1]
- ^ Hurricanes reaching Category 3 (111 miles per hour (179 km/h)) and higher on the 5-level Saffir–Simpson wind speed scale are considered major hurricanes.[4]
- ^ Due to the threat the developing system posed to the Gulf Coast of the United States, the National Hurricane Center initiated advisories it, designating it Potential Tropical Cyclone Three at 21:00 UTC (4:00 p.m. CDT) on June 17.[14]
- ^ Due to the threat the developing system posed to the countries and territories in the Lesser Antilles, the National Hurricane Center initiated advisories it, designating it Potential Tropical Cyclone Five at 21:00 UTC (5:00 p.m. AST) on June 30.[17]
- ^ Due to the threat the developing system posed to the countries and territories in the Lesser Antilles, the National Hurricane Center initiated advisories it, designating it Potential Tropical Cyclone Six at 21:00 UTC (5:00 p.m. AST) on August 9. [19]
- ^ Due to the threat the developing system posed to the countries and territories in the Leeward Islands, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Seven at 15:00 UTC (11:00 a.m. AST) on August 12.[21]
- ^ The mid-level remnants of Grace emerged offshore of the Pacific coast of southwestern Mexico, where they contributed to the formation of Tropical Storm Marty on August 23.[22][24]
- ^ The National Hurricane Center monitored Odette's remnants for possible tropical transition from September 19 to September 24. Though the cyclone did lose its frontal features, it never produced a sufficient amount of deep convection to be considered a tropical or subtropical cyclone again.[33]
- ^ The National Hurricane Center began monitoring Peter's remnants for possible regeneration on September 25. Although a well-defined surface low formed on September 28, the system never had the organized deep convection characteristics of a tropical cyclone.[34]
