Part of the 1933 Atlantic hurricane season

The 1933 Treasure Coast hurricane[nb 1] was the second-most intense tropical cyclone to strike the United States during the active 1933 Atlantic hurricane season. The eleventh tropical storm, fifth hurricane, and the third major hurricane of the season, it formed east-northeast of the Leeward Islands on August 31. The tropical storm moved rapidly west-northwestward, steadily intensifying to a hurricane. It acquired peak winds of 140 mph (220 km/h) and passed over portions of the Bahamas on September 3, including Eleuthera and Harbour Island, causing severe damage to crops, buildings, and infrastructure. Winds over 100 mph (160 km/h) affected many islands in its path, especially those that encountered its center, and many wharves were ruined.

Subsequently, it weakened and made landfall at Jupiter, Florida, early on September 4 with winds of 125 mph (205 km/h). The hurricane moved across the state, passing near Tampa before moving into Georgia and dissipating. In Florida, the strong winds of the cyclone blew buildings off their foundations, and numerous trees were prostrated in citrus groves. The Treasure Coast region received the most extensive destruction, and Stuart, Jupiter, and Fort Pierce were heavily damaged. The storm was locally regarded as the most severe on record in 50 years. Inland, the cyclone weakened rapidly but produced prodigious amounts of rain, causing a dam to collapse near Tampa. The storm caused $3 million in damage (1933 USD) after damaging or destroying 6,848 homes.

Unusually, the storm hit Florida less than 24 hours before another major hurricane bearing 125-mph (205-km/h) winds struck South Texas; never have two major cyclones hit the United States in such close succession.[2]
