The third tropical storm and second hurricane of the season, Charley formed as a subtropical low on August 13 along the Florida panhandle. After moving off the coast of South Carolina, the system transitioned into a tropical cyclone and intensified into a tropical storm on August 15. Charley later attained hurricane status before moving across eastern North Carolina. It gradually weakened over the north Atlantic Ocean before transitioning into an extratropical cyclone on August 20. Charley`s remnants remained identifiable for over a week until after crossing the British Isles and dissipating on August 30.
