An eyewall also began to form around a portion of its circulation.[173] At 18:05 UTC that same day, Ian made its third landfall near Georgetown, South Carolina, with sustained winds of 85 mph (140 km/h).[174] Ian began to weaken inland, and transitioned into a post-tropical cyclone over coastal South Carolina three hours after landfall.[175] The cyclone later dissipated over southern Virginia late on October 1.[176]
