At 500 PM EDT (2100 UTC), the center of Post-Tropical Cyclone Ian was located near latitude 33.9 North, longitude 79.2 West. The post-tropical cyclone is moving toward the north near 15 mph (24 km/h). Ian is forecast to move farther inland overnight over eastern South Carolina, move across central North Carolina early tomorrow and western Virginia by early Sunday. Maximum sustained winds have decreased to near 70 mph (110 km/h) with higher gusts. These winds are occurring primarily over water. Ian should continue to weaken overnight and dissipate over western North Carolina or Virginia late tomorrow.
Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. A WeatherFlow station at Oak Island, North Carolina recently reported sustained winds of 54 mph (87 km/h) with a gust to 78 mph (126 km/h). The estimated minimum central pressure is 982 mb (29.00 inches) based on surface observations.
STORM SURGE: 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.
* Cape Fear River...2-4 ft
* South Santee River to Duck, including Pamlico and Neuse
* Albemarle Sound...1-2 ft
WIND: Tropical storm conditions are expected to continue in portions of the warning area through overnight.
RAINFALL: Ian is expected to produce the following storm total rainfall:
* Northeast South Carolina: 4 to 8 inches, with local maxima of 12
* Central South Carolina, North Carolina, and southern Virginia:
3 to 6 inches with local maxima of 8 inches
* Elsewhere in Virginia, portions of West Virginia, Washington D.C.,
and Maryland: 1 to 3 inches, local maxima of 5 inches.
TORNADOES: A few tornadoes are possible through this evening across eastern North Carolina, shifting northward into southeast Virginia tonight through early Saturday morning.
SURF: Swells generated by Ian and a nearby frontal system are affecting the east coast of Florida, Georgia, the Carolinas, and the northwestern Bahamas. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
