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

life-threatening situation. Persons located within these areas

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 Storm Surge Watch means there is a possibility of life-

threatening inundation, from rising water moving inland from the

coastline, in the indicated locations during the next 48 hours.

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

DISCUSSION AND OUTLOOK

----------------------

At 500 AM EDT (0900 UTC), the center of Hurricane Dorian was located

near latitude 29.2 North, longitude 79.5 West. Dorian is moving

toward the north-northwest near 8 mph (13 km/h), and a northwest or

north-northwest motion is expected through this morning. A turn

toward the north is forecast by this evening, followed by a turn

toward the north-northeast on Thursday morning. On this track, the

core of Hurricane Dorian will move dangerously close to the Florida

east coast and the Georgia coast through tonight. The center of

Dorian is forecast to move near or over the coast of South Carolina

and North Carolina Thursday through Friday morning.

Maximum sustained winds are near 105 mph (165 km/h) with higher

gusts. Some weakening is expected during the next couple of days,

and Dorian is expected to remain a powerful hurricane during 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 175

miles (280 km).

The minimum central pressure reported by an Air Force Reserve Unit

Hurricane Hunter aircraft is 963 mb (28.44 inches).

HAZARDS AFFECTING LAND

----------------------

WIND: Tropical storm conditions are currently affecting portions of

the northeastern coast of Florida, and should begin along the

Georgia coast later this morning.

Hurricane conditions are expected somewhere within the Hurricane

Warning area in Florida today. Tropical storm conditions will begin

within the Hurricane Warning area in the Carolinas later today, with

hurricane conditions by 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

Volusia/Brevard County Line FL to Savannah River...3 to 5 ft

Sebastian Inlet FL to Volusia/Brevard County Line FL...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

office.

RAINFALL: Dorian is expected to produce the following rainfall

totals through Friday:

Coastal Carolinas...5 to 10 inches, isolated 15 inches.

Atlantic Coast from Daytona Beach, Florida to the Georgia-South

Carolina border...3 to 6 inches, with isolated 9 inches near the

Georgia coast.

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 through tonight. This risk will shift to along the

immediate Georgia coast and the coastal Carolinas today into

Thursday.
