The Post and Courier reported that at least 100 roads in the Charleston area were shut down due to storm surge flooding, and reported that by 10:30 a.m., NOAA's tidal gauge in the area was at 7.5 feet.
Shawn Gillen, Tybee Island's city manager, said waters appeared to be receding quickly but the flooding was extensive on the island of more than 3,000 residents. The order affects Edisto Beach in Colleton County; Daufuskie, Fripp, Hunting, Harbor and Hilton Head islands in Beaufort County; and Knolls and Tullifeeny islands in Jasper County.
Officials in Beaufort County say they will assess the damage from Tropical Storm Irma at daylight Tuesday and hope to have an announcement on whether evacuated residents can return a short time later.
The governor did not rule out more evacuations.
