DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Florence was located near latitude 33.7 North, longitude 80.5 West. Florence is moving toward the west near 3 mph (6 km/h). A turn toward the northwest with an increase in forward speed is expected on Sunday, followed by a turn toward the north and northeast with an additional increase in forward speed on Monday. On the forecast track, Florence`s center will move across the western Carolinas on Sunday and then recurve over the Ohio Valley and Northeast U.S. Monday and Tuesday. Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. Additional weakening is forecast while the center moves farther inland, and Florence is expected to become a tropical depression early Sunday. Tropical-storm-force winds extend outward up to 160 miles (260 km) to the east of the center near the coast and over water. Within the past hour or so, a sustained wind of 39 mph (63 km/h) with a gust to 51 mph (82 km/h) was reported at the Johnny Mercer Pier in Wrightsville Beach, North Carolina. A wind gust to 49 mph (79 km/h) was recently reported near Chester, South Carolina. The estimated minimum central pressure based on nearby surface observations is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Florence is expected to produce heavy and excessive rainfall in the following areas... Southern and western North Carolina...an additional 10 to 15 inches, with storm total accumulations up to 20 inches in western North Carolina and up to 40 inches in southeast North Carolina. This rainfall will produce catastrophic flash flooding and prolonged significant river flooding, with an elevated risk for landslides in western North Carolina. Northern South Carolina and southwestern Virginia...5 to 10 inches, isolated 15 inches. West-central Virginia into far eastern West Virginia, north of Roanoke and west of Charlottesville, 3 to 6 inches, isolated 8 inches. These rainfall amounts will result in life-threatening flash flooding and river flooding, along with an elevated risk for landslides. STORM SURGE: Water levels along the coast of North and South Carolina are gradually receding. Some minor coastal flooding is still possible through Sunday. For information specific to your area, please see products issued by your local National Weather Service forecast office. WIND: Tropical storm conditions will continue overnight in portions of the warning area along the coast and also over large portions of eastern North Carolina and extreme eastern South Carolina, with tropical-storm-force wind gusts spreading well inland. TORNADOES: A couple of tornadoes remain possible across North Carolina and northeastern South Carolina through Sunday. 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. Please consult products from your local weather office.
