For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. 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. A Tropical Storm Warning means that tropical storm conditions are expected within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the Mid-Atlantic coast of the United States should continue to monitor the progress of Dorian, as additional watches or warnings may be required later today. Interests in southeastern New England should also monitor the progress of the hurricane. 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 1100 PM EDT (0300 UTC), the eye of Hurricane Dorian was located near latitude 31.3 North, longitude 79.6 West. Dorian is moving toward the north near 7 mph (11 km/h). A turn to the north- northeast is anticipated on Thursday, with a turn toward the northeast on Thursday night. A northeastward motion at a faster forward speed is forecast on Friday. On the forecast track, the center of Dorian will continue to approach the coast of South Carolina tonight, move near or over the coast of South Carolina on Thursday, and then move near or over the coast of North Carolina Thursday night and Friday. Maximum sustained winds are now near 115 mph (185 km/h) with higher gusts. Dorian is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are expected during the next 12 hours, followed by slow weakening Thursday through Friday. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). The minimum central pressure reported by an Air Force plane was 955 mb (28.20 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are currently affecting portions of the Georgia and southern South Carolina coasts, and should begin along other portions of the South Carolina coast during the next several hours. Tropical storm conditions will begin elsewhere within the Hurricane Warning area in the Carolinas tonight, with hurricane conditions beginning on Thursday. Tropical storm conditions are expected in the Tropical Storm Warning area in the Mid-Atlantic states by Friday, with tropical storm conditions possible in the Tropical Storm Watch area Friday or Friday night. 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 could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Isle of Palms to Myrtle Beach SC...5 to 8 ft Savannah River to Isle of Palms SC...4 to 7 ft Myrtle Beach SC to Cape Lookout NC...4 to 7 ft Cape Lookout NC to Duck NC, including Pamlico and Albemarle Sounds and the Neuse and Pamlico Rivers...4 to 6 ft North of Mouth of St. Mary's River to Savannah River...3 to 5 ft Duck NC to Poquoson VA, including Hampton Roads...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: Coastal Carolinas...6 to 12 inches, isolated 15 inches. Coastal Georgia...2 to 4 inches, isolated 6 inches Far 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: Isolated tornadoes will be possible through Thursday across the coastal Carolinas. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT. Next complete advisory at 500 AM EDT. $$ Forecaster Avila
