DISCUSSION AND OUTLOOK
\n———————-
\nAt 1100 AM EDT (1500 UTC), the center of Hurricane Dorian was
\nlocated near latitude 32.5 North, longitude 79.1 West. Dorian is
\nmoving toward the north-northeast near 8 mph (13 km\/h). A turn
\ntoward the northeast is anticipated by tonight, and a northeastward
\nmotion at a faster forward speed is forecast on Friday. On the
\nforecast track, the center of Dorian will continue to move close to
\nthe coast of South Carolina today, and then move near or over the
\ncoast of North Carolina tonight and Friday. The center should move
\nto the southeast of extreme southeastern New England Friday night
\nand Saturday morning, and approach Nova Scotia later on Saturday.<\/p>\n

Reports from Air Force Reserve and NOAA Hurricane Hunter aircraft
\nindicate that maximum sustained winds are now near 110 mph (175
\nkm\/h) with higher gusts. Slow weakening is expected during the
\nnext few days. However, Dorian is expected to remain a powerful
\nhurricane as the center moves near the coasts of South and North
\nCarolina.<\/p>\n

Hurricane-force winds extend outward up to 60 miles (95 km) from the
\ncenter and tropical-storm-force winds extend outward up to 195 miles
\n(315 km). The Weatherflow station at Winyah Bay, South Carolina,
\nrecently reported sustained winds of 60 mph (97 km\/h) and a wind
\ngust of 76 mph (122 km\/h). Charleston International Airport
\nrecently reported sustained winds of 40 mph (64 km\/h) and a wind
\ngust of 56 mph (91 km\/h).<\/p>\n

The estimated minimum central pressure is 958 mb (28.29 inches).
\nNOAA buoy 41004, currently located inside the eye, has reported a
\nminimum pressure of 959.7 mb (28.34 inches).<\/p>\n

HAZARDS AFFECTING LAND
\n———————-
\nWIND: Tropical storm conditions are currently affecting portions of
\nthe Georgia and South Carolina coasts. Hurricane conditions are
\nexpected along portions of the South Carolina coast during the next
\nseveral hours.<\/p>\n

Tropical storm conditions are spreading along the coast of North
\nCarolina, and hurricane conditions are expected to begin later
\ntoday.<\/p>\n

Tropical storm conditions are expected in the Tropical Storm
\nWarning area in the Mid-Atlantic states by Friday, with tropical
\nstorm conditions possible in the Tropical Storm Watch area Friday
\nor Friday night.<\/p>\n

Tropical storm conditions are possible over portions of
\nsoutheastern Massachusetts by late Friday or early Saturday.<\/p>\n

STORM SURGE: The combination of a dangerous storm surge and the
\ntide will cause normally dry areas near the coast to be flooded by
\nrising waters moving inland from the shoreline. The water could
\nreach the following heights above ground somewhere in the indicated
\nareas if the peak surge occurs at the time of high tide…<\/p>\n

Awendaw SC to Myrtle Beach SC…5 to 8 ft
\nMyrtle Beach SC to Duck NC, including Pamlico and Albemarle Sounds
\nand the Neuse and Pamlico Rivers…4 to 7 ft
\nDuck NC to Poquoson VA, including Hampton Roads…2 to 4 ft
\nEdisto Beach SC to Awendaw SC…2 to 4 ft<\/p>\n

Water levels could begin to rise well in advance of the arrival of
\nstrong winds. The surge will be accompanied by large and
\ndestructive waves. Surge-related flooding depends on the how close
\nthe center of Dorian comes to the coast, and can vary greatly over
\nshort distances. For information specific to your area, please see
\nproducts issued by your local National Weather Service forecast
\noffice.<\/p>\n

RAINFALL: Dorian is expected to produce the following rainfall
\ntotals through Friday:<\/p>\n

Coastal Carolinas…6 to 12 inches, isolated 15 inches
\nFar southeast Virginia…3 to 8 inches
\nExtreme southeastern New England…2 to 4 inches<\/p>\n

This rainfall may cause life-threatening flash floods.<\/p>\n

SURF: Large swells will affect the northwestern Bahamas, and
\nthe entire southeastern United States coast from Florida through
\nNorth Carolina during the next few days. These swells are
\nlikely to cause life-threatening surf and rip current conditions.
\nPlease consult products from your local weather office.<\/p>\n

TORNADOES: Tornadoes are possible through this afternoon across
\neastern North Carolina and the upper South Carolina coast. The
\ntornado threat will continue tonight across eastern North Carolina
\ninto southeast Virginia.<\/p>\n
