Timeline of the 2010 Atlantic hurricane season

[1][nb 1] The season officially began on June 1, 2010, and ended on November 30, 2010, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin.

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 documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.

Additionally, 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 products.
