DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), data from an Air Force Reserve Unit Hurricane Hunter aircraft and NOAA Doppler weather radars from indicate that Florence was located near latitude 33.4 North, longitude 75.5 West. Florence is moving toward the northwest near 10 mph (17 km/h). This general motion, accompanied by a further decrease in forward speed, is expected to continue through today. A turn to the west-northwest and west at an even slower forward speed is expected tonight and Friday, and a slow west-southwestward motion is forecast Friday night and Saturday. On the forecast track, the center of Florence will approach the coasts of North and South Carolina later today, then move near or over the coast of southern North Carolina and northeastern South Carolina in the hurricane warning area tonight and Friday. A slow motion across portions of eastern South Carolina is forecast Friday night through Saturday night. Data from the aircraft and Doppler weather radars indicate that maximum sustained winds have decreased to near 105 mph (165 km/h) with higher gusts. Little change in strength is expected before the center reaches the coast, with weakening expected after the center moves inland. Florence is a large hurricane. Hurricane-force winds extend outward up to 80 miles (130 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). NOAA Buoy 41025, located near Diamond Shoals, North Carolina, recently reported a sustained wind of 54 mph (87 km/h). The latest minimum central pressure based on data from the aircraft is 955 mb (28.20 inches).
