The 1910 Cuba hurricane, popularly known as the Cyclone of the Five Days, was an unusual and destructive tropical cyclone that struck Cuba and the United States in October 1910. It formed in the southern Caribbean on October 9 and strengthened as it moved northwestward, becoming a hurricane on October 12. After crossing the western tip of Cuba, it peaked in intensity on October 16, corresponding to Category 4 on the Saffir–Simpson hurricane scale. That same day, the hurricane moved in a counterclockwise loop and hit Cuba again. It then tracked toward Florida, landing near Cape Romano. After moving through the state, it hugged the coast of the Southeastern United States on its way out to sea.
