DISCUSSION AND OUTLOOK
\n———————-
\nAt 800 AM EDT (1200 UTC), the center of Hurricane Dorian was located
\nnear latitude 29.5 North, longitude 79.6 West. Dorian is moving
\ntoward the north-northwest near 8 mph (13 km\/h), and a northwest or
\nnorth-northwest motion is expected through this morning. A turn
\ntoward the north is forecast by this evening, followed by a turn
\ntoward the north-northeast on Thursday morning. On this track, the
\ncore of Hurricane Dorian will move dangerously close to the Florida
\neast coast and the Georgia coast through tonight. The center of
\nDorian is forecast to move near or over the coast of South Carolina
\nand North Carolina Thursday through Friday morning.<\/p>\n

Maximum sustained winds are near 105 mph (165 km\/h) with higher
\ngusts. Some weakening is expected during the next couple of days.
\nHowever, Dorian is expected to remain a powerful hurricane during
\nthe next few days.<\/p>\n

Hurricane-force winds extend outward up to 60 miles (95 km) from
\nthe center, and tropical-storm-force winds extend outward up to
\n175 miles (280 km). The NOAA automated station at St. Augustine
\nBeach, Florida, recently reported sustained winds of 46 mph (74
\nkm\/h) and a wind gust of 59 mph (94 km\/h).<\/p>\n

The minimum central pressure reported by an Air Force Reserve Unit
\nHurricane Hunter aircraft is 964 mb (28.47 inches).<\/p>\n

HAZARDS AFFECTING LAND
\n———————-
\nWIND: Tropical storm conditions are currently affecting portions of
\nthe northeastern coast of Florida, and should begin along the
\nGeorgia coast later this morning.<\/p>\n

Hurricane conditions are expected somewhere within the Hurricane
\nWarning area in Florida today. Tropical storm conditions will begin
\nwithin the Hurricane Warning area in the Carolinas later today, with
\nhurricane conditions by tonight.<\/p>\n

STORM SURGE: The combination of a dangerous storm surge and the
\ntide will cause normally dry areas near the coast to be flooded by
\nrising waters moving inland from the shoreline. The water could
\nreach the following heights above ground somewhere in the indicated
\nareas if the peak surge occurs at the time of high tide…<\/p>\n

Isle of Palms to Myrtle Beach SC…5 to 8 ft
\nSavannah River to Isle of Palms SC…4 to 7 ft
\nMyrtle Beach SC to Cape Lookout NC…4 to 7 ft
\nCape Lookout NC to Duck NC, including Pamlico and Albemarle Sounds
\nand the Neuse and Pamlico Rivers…4 to 6 ft
\nVolusia\/Brevard County Line FL to Savannah River…3 to 5 ft
\nSebastian Inlet FL to Volusia\/Brevard County Line FL…2 to 4 ft
\nDuck NC to Poquoson VA, including Hampton Roads…2 to 4 ft<\/p>\n

Water levels could begin to rise well in advance of the arrival of
\nstrong winds. The surge will be accompanied by large and
\ndestructive waves. Surge-related flooding depends on the how close
\nthe center of Dorian comes to the coast, and can vary greatly over
\nshort distances. For information specific to your area, please see
\nproducts issued by your local National Weather Service forecast
\noffice.<\/p>\n

RAINFALL: Dorian is expected to produce the following rainfall
\ntotals through Friday:<\/p>\n

Coastal Carolinas…5 to 10 inches, isolated 15 inches.
\nAtlantic Coast from Daytona Beach, Florida to the Georgia-South
\nCarolina border…3 to 6 inches, with isolated 9 inches near the
\nGeorgia coast.
\nSoutheast Virginia…3 to 6 inches.<\/p>\n

This rainfall may cause life-threatening flash floods.<\/p>\n

SURF: Large swells will affect the northwestern Bahamas, and
\nthe entire southeastern United States coast from Florida through
\nNorth Carolina during the next several days. These swells are
\nlikely to cause life-threatening surf and rip current conditions.
\nPlease consult products from your local weather office.<\/p>\n

TORNADOES: A tornado or two are possible near the immediate east
\ncoast of Florida through tonight. This risk will shift to along the
\nimmediate Georgia coast and the coastal Carolinas today into
\nThursday.<\/p>\n
