Part of the 2010 Atlantic hurricane season

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.

Along the hurricane's path, 44 fatalities occurred, 8 of whom were in Saint Lucia. In the wake of the storm in Haiti, flooding exacerbated a cholera outbreak, indirectly causing more fatalities. However, direct impacts from the hurricane in Haiti were less than anticipated. Overall damage from the storm was $463.4 million.
