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.
Due to its unusual loop, initial reports suggested it was two separate storms that developed and hit land in rapid succession. Its track was subject to much debate at the time; eventually, it was identified as a single storm. Analysis of the event gave a greater understanding of weather systems that took similar paths.
The hurricane is considered one of the worst natural disasters in Cuban history. Damage was extensive, and thousands were left homeless. It also had a widespread impact in Florida, including the destruction of houses and flooding. Although total monetary damage from the storm is unknown, estimates of losses in Havana, Cuba exceed $1 million and in the Florida Keys, $250,000. At least 100 deaths occurred in Cuba alone.
