DISCUSSION AND OUTLOOK
At 800 PM EDT (0000 UTC), the large eye of Hurricane Dorian was
located near latitude 30.9 North, longitude 79.8 West. Dorian is
moving northward near 8 mph (13 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.
Reports from a NOAA Hurricane Hunter aircraft indicate that maximum
sustained winds remain near 110 mph (175 km/h) with higher gusts.
Some fluctuations in strength are possible tonight, followed by slow
weakening Thursday through Friday.
Hurricane-force winds extend outward up to 70 miles (110 km) from
the center and tropical-storm-force winds extend outward up to 195
miles (315 km).
The minimum central pressure reported by the Hurricane Hunter is
959 mb (28.31 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
Tropical storm conditions will begin elsewhere within the Hurricane
Warning area in the Carolinas later today, with hurricane conditions
beginning by late tonight and 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.
Tropical storm conditions along the northeastern Florida coast
should subside tonight.
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
Flagler/Volusia County Line FL to the Mouth of St. Mary's River...2
to 4 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
RAINFALL: Dorian is expected to produce the following rainfall
totals through Friday:
Coastal Carolinas...6 to 12 inches, isolated 15 inches.
Far southeast Virginia...3 to 6 inches.
Atlantic Coast from Daytona Beach, Florida to the Georgia-South
Carolina border...2 to 4 inches, isolated 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 along the immediate coast
of Georgia this afternoon. Isolated tornadoes are possible from this
evening through Thursday across the coastal Carolinas.
