Hurricane Alma was a rare June major hurricane in the 1966 Atlantic hurricane season. It was the earliest Atlantic hurricane in the calendar year in fifteen years, as well as the earliest continental U.S. hurricane strike since 1825. Alma developed on June 4 over Central America, and while moving through Honduras, it dropped heavy rainfall that killed at least 73 people in the city of San Rafael. Offshore northern Honduras, the system produced heavy rainfall in Swan Island. Alma moved northeastward and intensified into a hurricane on June 6. It crossed western Cuba, causing heavy crop damage and water shortages. Alma destroyed over 1,000 houses, and damage was estimated around $200 million (1966 USD). The storm killed 11 people in the country.
After crossing Cuba, Alma intensified further to reach winds of 115 mph (185 km/h) in the Gulf of Mexico. The hurricane passed west of Key West, Florida, causing a power outage and flooding. Alma dropped heavy rainfall and produced winds across most of Florida, which damaged crops and caused scattered power outages. The hurricane weakened before moving ashore near Apalachee Bay. Damage in Florida was estimated at $10 million, and there were six deaths in the state.
Alma crossed southeastern Georgia as a tropical storm, damaging a few houses and causing light damage. The storm re-intensified into a hurricane over the western Atlantic Ocean, and its outer rainbands dropped heavy rainfall in Wilmington, North Carolina. Alma encountered colder water temperatures and its intensity decreased to being an extratropical cyclone on June 13. Its remnants dissipated a day later over Massachusetts.
