DISCUSSION AND OUTLOOK
At 800 AM EDT (1200 UTC), the eye of Hurricane Dorian was located
near latitude 32.1 North, longitude 79.3 West. Dorian is now moving
toward the north-northeast near 8 mph (13 km/h). A turn toward
the northeast is anticipated by tonight, and a northeastward motion
at a faster forward speed is forecast on Friday. On the forecast
track, the center of Dorian will continue to move close to the coast
of South Carolina today, and then move near or over the coast of
North Carolina tonight and Friday. The center should move to the
southeast of extreme southeastern New England Friday night and
Saturday morning, and approach Nova Scotia later on Saturday.
Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Dorian is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in intensity are expected
this morning, followed by slow weakening through Saturday. However,
Dorian is expected to remain a hurricane for the next few days.
Hurricane-force winds extend outward up to 60 miles (95 km) from
the center, and tropical-storm-force winds extend outward up to
195 miles (315 km). NOAA buoy 41004, located a short distance north
of the eye, recently reported sustained winds of 60 mph (97 km/h)
and a wind gust of 76 mph (122 km/h). Charleston International
Airport recently reported a wind gust of 61 mph (98 km/h).
The estimated minimum central pressure based on Air Force Reserve
Hurricane Hunter data is 959 mb (28.32 inches). NOAA buoy 41004
recently reported a pressure of 976.0 mb (28.82 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are currently affecting portions of
the Georgia and South Carolina coasts. Hurricane conditions are
expected along portions of the South Carolina coast later this
Tropical storm conditions are spreading along the coast of North
Carolina, and hurricane conditions are expected to begin later
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 are possible over portions of
southeastern Massachusetts by late Friday or early Saturday.
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
Myrtle Beach SC to Duck NC, including Pamlico and Albemarle Sounds
and the Neuse and Pamlico Rivers...4 to 7 ft
Duck NC to Poquoson VA, including Hampton Roads...2 to 4 ft
Savannah River to Isle of Palms SC...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 8 inches
Coastal Georgia...1 to 2 inches
Extreme southeastern New England...2 to 4 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 few days. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
TORNADOES: A few tornadoes are possible through this afternoon near
the coastal South and North Carolina border area. This threat will
expand northeastward across the rest of eastern North Carolina
during the afternoon and continue into tonight.
