The disturbance began suddenly over the western Caribbean Sea, strengthening into a tropical storm on October 12 within hours of initial development. It intensified into a hurricane the next day, with a brief but slow westward path bringing it near Grand Cayman. There, the storm produced rough surf and torrential rainfall for several days, destroying all of the Cayman Islands' crops and damaging coastal property; the storm proved to be the rainiest hurricane in Grand Cayman's history. On October 16, the developing hurricane made a sharp turn northward and accelerated. It made landfall on western Cuba two days later at peak strength with winds of 145 mph (230 km/h), making it a Category 4 hurricane. Cuba, hardest hit by the storm, saw at least 300 people killed and suffered extensive damage inflicted by winds and storm surge, especially in the Havana area. Numerous ships sank in Havana Harbor amid agitated waters and marine debris.
