Hurricane Dorian Brings Wind and Rain to the Carolinas

Hurricane Dorian brought wind and rain to the Carolinas on Thursday while the center move just off the coast.  At 11:00 p.m. EDT on Thursday the center of Hurricane Dorian was located at latitude 33.6°N and longitude 77.4°W which put it about 70 miles southwest of Cape Lookout, North Carolina.  Dorian was moving toward the northeast at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 958 mb.

A Hurricane Warning was in effect for the portion of the coast from Edisto Beach, South Carolina to the North Carolina/Virginia border including Albemarle and Pamlico Sounds. Tropical Storm Warnings were in effect for the portion of the coast from the North Carolina/Virginia border to Fenwick Island, Delaware, for Chesapeake Bay south of Drum Point and for the Tidal Potomac south of Cobb Island. A Tropical Storm Warning was in effect for the portion of the coast from Woods Hole to Sagamore Beach, Massachusetts including Martha’s Vineyard and Nantucket. A Hurricane Watch has been issued for all of Nova Scotia. Tropical Storm Watches have been issued for Prince Edward Island, for the Magdalen Islands and for New Brunswick from Fundy National Park to Shediac. A Tropical Storm Watch was issued for Newfoundland from Francois to Boat Harbor.

Hurricane Dorian weakened very slowly on Thursday while the center of circulation moved just off the coast.  The pressure remained nearly steady around 958 mb.  A circular eye with a diameter of 35 miles (55 km) was at the center of circulation.  A ring of thunderstorms surrounded the eye and the strongest winds were in that ring of storms.  Winds to hurricane force extended out about 60 miles (95 km) from the center of Hurricane Dorian.  Winds to tropical storm force extended out about 220 miles (330 km) from the center.

The core of Hurricane Dorian with the strongest winds remained over the Atlantic Ocean.  Numerous location along the coast of South Carolina and North Carolina reported winds to topical storm force.  Rainbands rotating around the northern half of Dorian dropped locally heavy rain over coastal areas of South Carolina and North Carolina.  Thunderstorms in some of the bands generated tornadoes and there were scattered reports of wind damage.  Hurricane Dorian caused a storm surge of 4 to 7 feet (1.3 to 2.3 meters) along the coast.

An upper level trough over the eastern U.S. began to steer Hurricane Dorian toward the northeast.  Dorian began to move faster later on Thursday.  The upper level trough will steer Hurricane Dorian rapidly toward the northeast during the next few days.  On its anticipated track Dorian will bring wind and rain to eastern North Carolina on Friday.  Dorian will also cause a storm surge along the coast.  Hurricane Dorian will pass southeast of New England on Friday night.  Dorian will bring wind and rain to the Canadian Maritime provinces and Newfoundland during the weekend.
