The 2000 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. There was above-normal activity during the season,[nb 1] with nearly all its activity occurring during a three-month period, August–October.[2] The season officially began on June 1, 2000 and ended on November 30, 2000. These dates, adopted by convention, historically describe the period in each year when most tropical systems form.[3] Although two tropical depressions formed in June, the first named storm, Alberto, did not arise until August 4. The season's final storm, an unnamed subtropical storm, became extratropical on October 29.
The 2000 season produced 15 cyclones of at least tropical (14) or subtropical (1) storm strength. Four of the tropical storms became hurricanes, of which three developed into major hurricanes.[nb 2] There were also four depressions that failed to reach tropical storm strength. The two most significant storms of the season, in terms of loss of life and damage, were Hurricanes Gordon and Keith. Gordon made land fall in the eastern Yucatán Peninsula, traversed the Gulf of Mexico, and made landfall along the Gulf Coast of the United States. Keith made landfall in Belize, crossed the Yucatán, moved over the Gulf, and made landfall in northeastern Mexico.[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.
The time stamp for each event is first stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 = midnight UTC.[5] 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) prior to 2020 were: Atlantic, Eastern, and Central.[6] 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.
