The 2023 Atlantic hurricane season is the current hurricane season, the annual period of tropical cyclogenesis in the Atlantic Ocean in the Northern Hemisphere. The season officially began on June 1, 2023, and will end on November 30, 2023. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclones form in the Atlantic.[1] However, tropical cyclone formation is possible at any time of the year, as was the case this season, when an unnamed subtropical storm formed on January 16.[2]

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).[3] 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.[4] 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

This system was not given the subtropical storm designation by the National Hurricane Center until May 11, 2023, following a review of data gathered on it operationally. While retroactively recognized as the first storm of the 2023 Atlantic hurricane season, it was not given a name.[2]
The National Hurricane Center continued to monitor Cindy's remnants until June 28 due to potential for regeneration.[12]
The National Hurricane Center continued to monitor Emily's remnants until August 25 due to potential for regeneration.[25]
Due to the threat the developing system posed to south Texas, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Nine at 15:00 UTC (10:00 a.m. CDT) on August 21.[27]
The National Hurricane Center continued to monitor ex-Franklin until September 7 due to potential for regeneration.[63]
On September 16, Extratropical Cyclone Lee made landfall on Long Island, in southwestern Nova Scotia, at 20:00 UTC (4:00 p.m. AST) with sustained winds of 70 mph (115 km/h),[91] and near St. John, New Brunswick a few hours later. Then, overnight into September 17, it traversed Prince Edward Island, on its way towards Newfoundland.[92]
Due to the threat the developing system posed to the southeastern U.S. coast, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Sixteen at 15:00 UTC (11:00 a.m. EDT) on September 21.[101]
