DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the center of Hurricane Dorian was located near latitude 27.7 North, longitude 78.7 West. Dorian is moving toward the northwest near 6 mph (9 km/h), and a slightly faster motion toward the northwest or north-northwest is expected tonight. A turn toward the north is forecast by Wednesday evening, followed by a turn toward the north-northeast Thursday morning. On this track, the core of Hurricane Dorian will move dangerously close to the Florida east coast and the Georgia coast tonight through Wednesday night. The center of Dorian is forecast to move near or over the coast of South Carolina and North Carolina Thursday through Friday morning. Maximum sustained winds are near 110 mph (175 km/h) with higher gusts. Dorian is expected to remain a powerful hurricane during the next couple of days. Dorian has become a larger hurricane. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm- force winds extend outward up to 175 miles (280 km). The latest minimum central pressure based on Air Force Reserve reconnaissance data is 959 mb (28.32 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue on Grand Bahama Island and along the Treasure Coast of Florida tonight. Tropical Storm conditions are expected to begin within the Tropical Storm Warning area in north Florida and Georgia late tonight or early Wednesday. Hurricane conditions are expected somewhere within the Hurricane Warning area in Florida overnight. Tropical Storm conditions will begin within the Hurricane Warning area in the Carolinas Wednesday, with hurricane conditions by Wednesday night. STORM SURGE: Water levels should very slowly subside on Grand Bahamas Island and the Abaco Islands through tonight. Near the coast, the surge will be accompanied by large and destructive waves. 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 could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Savannah River to Cape Lookout NC...4 to 7 ft Volusia/Brevard County Line FL to Savannah River...3 to 5 ft Cape Lookout NC to Duck NC, including Pamlico and Albemarle Sounds and the Neuse and Pamlico Rivers...3 to 5 ft Jupiter Inlet FL to Volusia/Brevard County Line FL...2 to 4 ft Water levels could begin to rise well in advance of the arrival of strong winds. The surge will be accompanied by large and destructive waves. Surge-related flooding depends on the how close the center of Dorian comes to the coast, 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: Dorian is expected to produce the following rainfall totals through Friday: Northwestern Bahamas...Additional 1 to 3 inches, isolated storm totals over 30 inches. Coastal Carolinas...5 to 10 inches, isolated 15 inches. Atlantic Coast from the Florida peninsula north of West Palm Beach through Georgia and across southeast Virginia...3 to 6 inches This rainfall may cause life-threatening flash floods. SURF: Large swells will affect the northwestern Bahamas, and the entire southeastern United States coast from Florida through North Carolina during the next several days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. TORNADOES: A tornado or two are possible near the immediate east coast of Florida through tonight. This risk will shift to along the immediate coastal Georgia and the coastal Carolinas on Wednesday into Thursday. NEXT ADVISORY ------------- Next intermediate advisory at 800 PM EDT. Next complete advisory at 1100 PM EDT. $$ Forecaster Brown NNNN
