Additional watches may be required later today. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 200 PM AST (1800 UTC), the eye of Hurricane Florence was located near latitude 27.1 North, longitude 66.2 West. Florence is moving toward the west-northwest near 17 mph (28 km/h). A west- northwestward to northwestward motion with a slight increase in forward speed are expected during the next couple of days. On the forecast track, the center of Florence will move over the southwestern Atlantic Ocean between Bermuda and the Bahamas through Wednesday, and approach the coast of North Carolina or South Carolina in the hurricane watch area Thursday and Friday. Maximum sustained winds are near 130 mph (215 km/h) with higher gusts. Florence is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Florence is expected to begin re- strengthening later today and continue a slow strengthening trend for the next day or so. While some weakening is expected on Thursday, Florence is expected to be an extremely dangerous major hurricane through landfall. Hurricane-force winds have expanded outward and now extend up to 60 miles (95 km) from the center. Tropical-storm-force winds have also expanded and now extend outward up to 170 miles (280 km) from the center. The estimated minimum central pressure is 950 mb (28.06 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 if peak surge occurs at the time of high tide... Edisto Beach to Murrells Inlet...2-4 ft Murrells Inlet to Cape Fear...4-6 ft Cape Fear to Cape Lookout including The Neuse and Pamlico River...6-12 ft Cape Lookout to Ocracoke Inlet...5-8 ft Ocracoke Inlet to North Carolina/Virginia Border...3-5 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 depends on the relative timing of the surge and the tidal cycle, and 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 total rainfall accumulations of 15 to 20 inches with isolated maximum amounts to 30 inches near the storm's track over portions of the Carolinas and Mid-Atlantic States from late this week into early next week. This rainfall could produce catastrophic flash flooding and significant river flooding. WIND: Hurricane conditions are possible within the watch area by late Thursday or Thursday night, with tropical storm conditions possible by Thursday morning.

Florence is moving toward the northwest near 16 mph (26 km/h) and this general motion, accompanied by a gradual decrease in forward speed, is expected to through Saturday. On the forecast track, the center of Florence will move over the southwestern Atlantic Ocean between Bermuda and the Bahamas today, and approach the coast of North Carolina or South Carolina in the hurricane warning area on Thursday and Friday and move slowly near the coastline through Saturday. The reconnaissance aircraft found that maximum sustained winds have decreased to near 125 mph (205 km/h) with higher gusts. Florence is now a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in strength will be possible through Thursday morning. Although slow weakening is expected to begin by late Thursday, Florence is still forecast to be an extremely dangerous major hurricane when it nears the U.S. coast late Thursday and Friday. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). A NOAA buoy located about 100 miles northeast of Florence's eye recently reported a sustained wind of 53 mph (85 km/h) and a gust to 74 mph (119 km/h). The minimum central pressure based on reports from the reconnaissance aircraft is estimated to be 948 mb (27.99 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 if peak surge occurs at the time of high tide... Cape Fear NC to Cape Lookout NC, including the Neuse, Pamlico, Pungo, and Bay Rivers...9-13 ft North Myrtle Beach SC to Cape Fear NC...6-9 ft Cape Lookout NC to Ocracoke Inlet NC...6-9 ft South Santee River SC to North Myrtle Beach SC...4-6 ft Ocracoke Inlet NC to Salvo NC...4-6 ft Salvo NC to North Carolina/Virginia Border...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 depends on the relative timing of the surge and the tidal cycle, and 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... Coastal North Carolina...20 to 30 inches, isolated 40 inches. This rainfall would produce catastrophic flash flooding and significant river flooding. South Carolina, western and northern North Carolina...5 to 10 inches, isolated 20 inches. Elsewhere in the Appalachians and Mid-Atlantic states...3 to 6 inches, isolated 12 inches. WIND: Hurricane conditions are expected to reach the coast within the hurricane warning area late Thursday or Friday. Winds are expected to first reach tropical storm strength on Thursday, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. TORNADOES: A few tornadoes are possible in eastern North Carolina beginning late Thursday morning. 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.

DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the center of Tropical Storm Florence was located near latitude 33.6 North, longitude 79.6 West. Florence is moving slowly toward the west near 2 mph (4 km/h) and a slow westward motion is expected to continue through today. A turn toward the west-northwest and northwest is expected on Sunday. Florence is forecast to turn northward through the Ohio Valley by Monday. Radar data and surface observations indicate that maximum sustained winds have decreased to near 45 mph (75 km/h) with higher gusts, mainly to the east of the center in heavy rainbands over water. Gradual weakening is forecast while Florence moves farther inland during the next couple of days, and it is expected to weaken to a tropical depression by tonight. Tropical-storm-force winds extend outward up to 150 miles (240 km) from the center. A sustained wind of 38 mph (61 km/h) with a gust to 45 mph (72 km/h) was recently reported at the Johnny Mercer Pier in Wrightsville Beach, North Carolina. A sustained wind of 38 mph (61 km/h) with a gust to 48 mph (78 km/h) was recently reported by a NOAA C-MAN station at Cape Lookout, North Carolina. The estimated minimum central pressure based on nearby surface observations is 995 mb (29.38 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... The Neuse, Pamlico, Pungo, and Bay Rivers...3-5 ft Cape Lookout NC to Cape Fear NC...3-5 ft Ocracoke Inlet NC to Cape Lookout NC...2-4 ft Cape Fear NC to Myrtle Beach 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... Southern and central portions of North Carolina into far northeast South Carolina...an additional 15 to 20 inches, with storm totals between 30 and 40 inches along the North Carolina coastal areas south of Cape Hatteras. This rainfall will continue to produce catastrophic flash flooding and prolonged significant river flooding. Remainder of northern South Carolina into western North Carolina and southwest 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. A preliminary report from a cooperative observer near Swansboro, North Carolina, indicates that more than 30 inches of rain has fallen so far. In Newport, North Carolina, more than 24 inches of rainfall has been measured. WIND: Tropical storm conditions will continue today 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 few tornadoes are possible in southeastern North Carolina northeastern South Carolina today through tonight. 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.
