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 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. 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. Interests elsewhere along the southeast and Mid-Atlantic coasts of the United States should continue to monitor the progress of Dorian, as additional watches or warnings may be required today. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the eye of Hurricane Dorian was located by NWS Doppler radar near latitude 27.5 North, longitude 78.7 West. Dorian is moving toward the northwest near 5 mph (7 km/h), and a slightly faster motion toward the northwest or north-northwest is expected later today and 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 extremely dangerous Hurricane Dorian will gradually move north of Grand Bahama Island through this evening. The hurricane will then move dangerously close to the Florida east coast late today through Wednesday evening, very near the Georgia and South Carolina coasts Wednesday night and Thursday, and near or over the North Carolina coast late Thursday and Thursday night. Data from reconnaissance aircraft indicate that the maximum sustained winds remain near 110 mph (175 km/h) with higher gusts. Dorian is expected to remain a powerful hurricane during the next couple of days. 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 data from Air Force Reserve and NOAA reconnaissance aircraft is 959 mb (28.32 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm and hurricane conditions will continue on Grand Bahama Island through tonight. Hurricane conditions are expected somewhere within the Hurricane Warning area in Florida overnight. Hurricane conditions are possible in the Hurricane Watch area as early as Wednesday and could spread northward within the watch area through Thursday. In South Florida, tropical storm conditions are expected within the Tropical Storm Warning area through today. Along the coast of northeastern Florida and Georgia, tropical storm conditions are expected within the Tropical Storm Warning area on Wednesday. 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... Flagler/Volusia County Line FL to Cape Lookout NC...4 to 7 ft Jupiter Inlet FL to the Flagler/Volusia County Line FL...3 to 5 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 2 to 4 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...3 to 6 inches, isolated 9 inches. Southeast Virginia...2 to 4 inches, isolated 6 inches. This rainfall may cause life-threatening flash floods. SURF: Large swells are affecting the northwestern Bahamas, the Florida east coast, and the coast of Georgia. These swells are expected to spread northward along much of the remainder of the southeastern United States coast during the next couple of 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.
