Life-threatening storm surge and hurricane conditions expected

30 Sep 2022 / North & South Carolina, United States

At 500am EDT (0900 UTC), the center of Hurricane Ian was located near latitude 30.8 North, longitude 79.1 West. Ian is moving toward the north-northeast near 9 mph (15 km/h). A turn toward the north with an increase in forward speed is expected this morning, followed by a turn toward the north-northwest by tonight.

On the forecast track, the center of Ian will approach and reach the coast of South Carolina today, and then move farther inland across eastern South Carolina and central North Carolina tonight and Saturday.

Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Little change in strength is expected before Ian reaches the coast later today. Rapid weakening is expected after landfall, and Ian is forecast to become an extratropical low over North Carolina tonight or on Saturday. The low is then expected to dissipate by Saturday night.

Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 485 miles (780 km)...

…The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide:
Edisto Beach to Little River Inlet...4-7 ft
Little River Inlet to Cape Fear...3-5 ft
Savannah River to Edisto Beach...3-5 ft
Flagler/Volusia County Line to Savannah River...2-4 ft
Cape Fear River...2-4 ft
St. Johns River...2-4 ft
East of Cape Fear to Duck, including Pamlico and Neuse Rivers...2-4 ft
Patrick Air Force Base to Flagler/Volusia County Line... 1-3 ft
Albemarle Sound...1-2 ft…

…Tropical storm conditions are occurring in parts of the warning areas on the coasts of Georgia and the Carolinas, and hurricane conditions are expected to begin in the Hurricane Warning

area in South Carolina and southeastern North Carolina by this afternoon. Hurricane conditions are possible within the Hurricane Watch area in North Carolina by this afternoon.

Ian is expected to produce the following storm total rainfall:
Northeast South Carolina: 4 to 8 inches, with local maxima of 12 inches.

Central South Carolina, North Carolina, and southern Virginia: 3-6 inches with local maxima of 8 inches across northwest North Carolina and southwest Virginia…
