The 2024 Atlantic hurricane season is the current cycle of the annual tropical cyclone season in the Atlantic Ocean in the Northern Hemisphere. The season officially began on June 1, and will end on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean (over 97%).[1] No subtropical or tropical development occurred in the Atlantic prior to the start of the season, and the season got off to the slowest start since 2014. Even so, hurricane researchers are predicting an above-normal number of named storms this year.[nb 1][3]
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).[4] 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.[5] 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.

^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.[6]
^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.[41]
