The 1947 Atlantic hurricane season was the first Atlantic hurricane season to have tropical storms labeled by the United States Air Force. The season officially began on June 16, 1947, and ended on November 1, 1947. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the first tropical cyclone developed on June 13, while the final system was absorbed by a cold front on December 1. There were 10 tropical storms; 5 of them attained hurricane status, while two became major hurricanes, which are Category 3 or higher on the modern day Saffir–Simpson scale. Operationally, the third tropical storm was considered two separate tropical cyclones, resulting in the storm receiving two names. The eighth tropical storm went undetected and was not listed in HURDAT until 2014.
Nearly all tropical storms impacted land during the season, some of which caused many fatalities and left destruction. The second storm caused severe flooding and mudslides in Mexico, leaving at least 48 dead and 43 others missing. In September, the strongest and costliest hurricane of the season, the Fort Lauderdale hurricane, left severe damage in Florida, Louisiana, and Mississippi due to strong winds, heavy rainfall, and abnormally high tides. There were 51 fatalities and about $160.2 million (1947 USD) in damage.[nb 1] The ninth storm, also known as the Cape Sable hurricane, caused additional flooding in South Florida and left wind damage in Georgia and South Carolina. The storm left about $20 million in damage. Overall, the systems of the season caused about $184.2 million in damage and at least 101 fatalities.
