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
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
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
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
