The 2010 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was one of the most active Atlantic hurricane seasons since record keeping began in 1851 as 19 named storms formed. 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. The first storm to form was Hurricane Alex, on June 25; and the last to dissipate was Hurricane Tomas, on November 7.

Hurricane Tomas was a moderately powerful late-season tropical cyclone which is the latest Atlantic hurricane on record in the calendar year to strike the Windward Islands. The nineteenth named storm and twelfth hurricane of the 2010 Atlantic hurricane season, Tomas developed from a tropical wave east of the Windward Islands on October 29. Quickly intensifying into a hurricane, it moved through the Windward Islands and passed over Saint Lucia. After reaching Category 2 status on the Saffir–Simpson scale, Tomas quickly weakened to a tropical storm in the central Caribbean Sea, due to strong wind shear and dry air. Tomas later reintensified into a hurricane near the Windward passage.
