during the next 36 hours in the indicated locations. For a depiction
of areas at risk, please see the National Weather Service Storm
Surge Watch/Warning Graphic, available at hurricanes.gov. This is a

should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area. Preparations to protect life and
property should be rushed to completion.

A Hurricane Watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Warning means that tropical storm conditions are
expected within the warning area within 36 hours.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere along the Mid-Atlantic coast of the United
States should continue to monitor the progress of Dorian, as
additional watches or warnings may be required later today.
Interests in southeastern New England should also monitor the
progress of the hurricane.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the eye of Hurricane Dorian was located
near latitude 31.4 North, longitude 79.6 West. Dorian is moving
toward the north near 7 mph (11 km/h). A turn to the north-
northeast is anticipated today, with a turn toward the northeast
tonight. 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 this morning,
move near or over the coast of South Carolina later today, and then
move near or over the coast of North Carolina tonight and Friday.

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.

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). A sustained wind of 49 mph (79 km/h) with a gust
to 57 mph (92 km/h) was recently reported at Winyah Bay, South
Carolina.

The minimum central pressure reported by an Air Force plane was 957
mb (28.26 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
morning.

Tropical storm conditions will begin along the coast of North
Carolina later this morning, with hurricane conditions beginning
later today.

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.

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
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
office.

RAINFALL: Dorian is expected to produce the following rainfall
totals through Friday:

Coastal Carolinas...6 to 12 inches, isolated 15 inches.
Coastal Georgia...2 to 4 inches, isolated 6 inches
Far 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: Isolated tornadoes will be possible through today
across the coastal Carolinas.
