The 2010 Atlantic hurricane season was one of the most active Atlantic hurricane seasons since records began in 1851 in which nineteen named storms formed.[1][nb 1] The season officially began on June 1 (with Hurricane Alex, the first hurricane of the season forming on June 15) and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin.[3] The season's final storm, Hurricane Tomas, dissipated on November 7.

The season produced twenty-one tropical cyclones, of which nineteen strengthened into tropical storms; twelve became hurricanes, and five further intensified into major hurricanes.[nb 2] The two most significant storms of the season, in terms of damage and loss of life, were hurricanes Igor and Tomas. Igor was one of the largest storms by gale diameter on record, and one that attained maximum sustained winds of 155 mph (250 km/h) before striking Newfoundland as a much weaker storm several days later. Tomas was a late-season tropical cyclone that rapidly intensified to reach maximum sustained winds of 100 mph (160 km/h) as it entered the eastern Caribbean Sea. Though the system did not make landfall, it severely affected the Greater Antilles, and impacted the southeastern Bahamas as a tropical storm before quickly moving into the open Atlantic.

This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.

Notes

  1. ^ An average season, as defined by the National Oceanic and Atmospheric Administration, has twelve tropical storms, six hurricanes and two major hurricanes.[2]
  2. ^ A major hurricane is a storm that ranks as Category 3 or higher on the Saffir–Simpson hurricane scale.[4]
  3. ^ The figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (knots, miles, or kilometers), following the convention used in the National Hurricane Center's operational products for each storm.[5] All other units are rounded to the nearest digit.
