DISCUSSION AND OUTLOOK ---------------------- At 200 AM EDT (0600 UTC), the center of Post-Tropical Cyclone Ian was located near latitude 35.4 North, longitude 79.7 West. The post-tropical cyclone is moving toward the north near 13 mph (20 km/h). This general motion with a decrease in forward speed is expected today as Ian moves farther inland across central North Carolina and Virginia. Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. These winds are occurring over water off the North Carolina coast. Ian is forecast to weaken further today and dissipate by early Sunday. Tropical-storm-force winds extend outward up to 275 miles (445 km) east of the center over the Atlantic waters. The estimated minimum central pressure based on surface observations is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Ian can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/text/MIATCDAT4.shtml. STORM SURGE: Surge related flooding will continue to recede along portions of the North Carolina coast, including the Pamlico Sound and Neuse River as well as the Albemarle Sound. For information specific to your area, please see products issued by your local National Weather forecast office. WIND: Wind gusts to tropical storm force are still possible over portions of North Carolina and southern Virginia early this morning as Ian moves farther inland. RAINFALL: Ian is expected to produce 3 to 6 inches, with local maxima of 8 inches across portions of North Carolina, West Virginia, and the southern Mid-Atlantic states. Major to record river flooding will continue across central Florida through next week. Considerable flash, urban and small stream flooding is possible across portions of North Carolina and southern Virginia through this morning, with minor river flooding possible over Coastal Carolinas. Limited flooding is possible across portions of the southern Mid-Atlantic over the weekend. TORNADOES: A brief tornado remains possible through this morning across far southeast Virginia and the southern Delmarva Peninsula. 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.
