Debby made landfall in Florida in the Big Bend region as a Category 1 hurricane before moving off the eastern U.S. coastline and making another landfall as a tropical storm in South Carolina. Ernesto affected the northern Leeward Islands and Puerto Rico with tropical storm conditions, while later moving directly over Bermuda as a Category 1 hurricane.
