DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the center of Hurricane Florence was located near latitude 34.0 North, longitude 78.0 West. Florence is moving toward the west-southwest near 3 mph (6 km/h). A slow westward to west-southwestward motion is expected today through Saturday. On the forecast track, the center of Florence will move further inland across extreme southeastern North Carolina and extreme eastern South Carolina today and Saturday. Florence will then move generally northward across the western Carolinas and the central Appalachian Mountains early next week. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Gradual weakening is forecast later today and tonight. Significant weakening is expected over the weekend and into early next week while Florence moves farther inland. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). A wind gust to 75 mph (120 km/h) was recently reported at the National Ocean Service station in Wrightsville Beach, and a 72 mph (116 km/h) was recently reported at a Weatherflow site just north of Cape Fear at Federal Point. The estimated minimum central pressure based on surface observations is 958 mb (28.29 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: The combination of a dangerous 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 has the potential to reach the following heights above ground... Cape Fear NC to Cape Lookout NC...7-11 ft, with locally higher amounts in the Neuse, Pamlico, Pungo, and Bay Rivers Cape Lookout NC to Ocracoke Inlet NC...6-9 ft South Santee River SC to Cape Fear NC...4-6 ft Ocracoke Inlet NC to Salvo NC...4-6 ft Salvo NC to Duck NC...2-4 ft Edisto Beach SC to South Santee River SC...2-4 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and destructive waves. Surge-related flooding can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. RAINFALL: Florence is expected to produce heavy and excessive rainfall in the following areas... Southeastern coastal North Carolina into far northeastern South Carolina...an additional 20 to 25 inches, with isolated storm totals of 30 to 40 inches. This rainfall will produce catastrophic flash flooding and prolonged significant river flooding. Remainder of South Carolina and North Carolina into southwest Virginia...5 to 10 inches, isolated 15 inches. This rainfall will produce life-threatening flash flooding. Rainfall totals exceeding 14 inches thus far have been reported at several locations across southeastern North Carolina. TORNADOES: A few tornadoes are possible in eastern North Carolina today. SURF: Swells generated by Florence are affecting Bermuda, portions of the U.S. East Coast, and the northwestern and central Bahamas. These swells are likely to cause life-threatening surf and rip current conditions. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM EDT. Next complete advisory at 500 PM EDT.
