The 2024 Atlantic hurricane season was the annual cycle of tropical cyclone formation over the Atlantic Ocean north of the equator. The season officially began on June 1 and ended on November 30. This is historically the period during which most subtropical or tropical cyclogenesis occurs over the Atlantic Ocean.[1] The first system, Tropical Storm Alberto, formed on June 19; the final system, Tropical Storm Sara, dissipated on November 18.

Activity during the season was above average, as defined by the National Hurricane Center (NHC),[nb 1] with 18 named storms developing; of them, 11 became hurricanes, and 5 strengthened further to become major hurricanes.[nb 2] Among the systems making landfall during the season, four did so at major hurricane strength. Beryl devastated the islands of Carriacou and Petite Martinique in Grenada.[3] In September, Helene cut a destructive path through the Southeastern United States and the central Appalachian Mountains.[4] The following month, Milton made landfall in Florida, causing severe damage.[5] Then, in November, Rafael made landfall in Artemisa, Cuba.[6]

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released during the season, meaning that data from post-storm NHC reviews has been included.

The time stamp for each event is first stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 = midnight UTC.[7] The NHC 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.[8] In this timeline, the respective area time is included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (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

  1. ^ An average Atlantic hurricane season, as defined by the National Hurricane Center, has 14 tropical storms, 7 hurricanes and 3 major hurricanes.[2]
  2. ^ A major hurricane is a hurricane that reaches Category 3 or higher on the five-level Saffir–Simpson scale, with 1-minute sustained winds higher than 110 miles per hour (178 km/h).[1]
  3. ^ Due to the threat the developing system posed to northeastern Mexico and South Texas, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone One at 21:00 UTC (4:00 p.m. CDT) on June 17.[9]
  4. ^ The position is as of 06:00 UTC (1:00 a.m. CDT) on July 8.[3]
  5. ^ Due to the threat the developing system posed to Florida, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Four at 15:00 UTC (11:00 a.m. EDT) on August 2.[12]
  6. ^ Due to the threat the developing system posed to the Leeward Islands, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Five at 21:00 UTC (5:00 p.m. AST) on August 11.[14]
  7. ^ Due to the threat the developing system posed to Texas and Louisiana, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Six at 21:00 UTC (4:00 p.m. CDT) on September 8.[16]
  8. ^ Due to the threat the developing system posed to Mexico and Cuba, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Nine at 15:00 UTC (11:00 a.m. EDT) on September 23.[19]
  9. ^ On November 3, daylight saving time ended in many areas of the basin, resulting in the gap between local time and Coordinated Universal Time widening by one hour.[27]
  10. ^ Due to the threat the developing system posed to Jamaica and the Cayman Islands, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Eighteen at 21:00 UTC (4:00 p.m. EST) on November 3.[28]
  11. ^ Due to the threat the developing system posed to Nicaragua and Honduras, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Nineteen at 21:00 UTC (4:00 p.m. EST) on November 13.[29]
