DISCUSSION AND OUTLOOK
At 800 PM EDT (0000 UTC), the center of Hurricane Dorian was located
near latitude 28.1 North, longitude 78.8 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
Maximum sustained winds are near 110 mph (175 km/h) with higher
gusts. Dorian is expected to remain a powerful hurricane during the
next few 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). NOAA buoy
41010 just north of the center recently reported a sustained wind
of 67 mph (107 km/h) and a wind gust of 83 mph (133 km/h).
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 for a few
more hours. 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
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 during the next several hours. This risk will
shift to along the immediate coasts of Georgia and the Carolinas on
Wednesday into Thursday.
