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.

Hurricane Florence Wobbles Closer to North Carolina

Hurricane Florence wobbled closer to the coast of North Carolina on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Hurricane Florence was located at latitude 34.0°N and longitude 76.8°W which put it about 60 miles east-southeast of Wilmington, North Carolina.  Florence was moving toward the northwest at 6 m.p.h.  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 956 mb.

A Hurricane Warning was in effect for the portion of the coast from South Santee River, South Carolina to Duck, North Carolina including Pamlico and Albemarle Sounds.  A Tropical Storm Warning was in effect for the portion of the coast from Edisto Beach to South Santee River, South Carolina.  A Tropical Storm Warning was also in effect for the portion of the coast from Duck, North Carolina to Cape Charles Light, Virginia and for Chesapeake Bay south of New Point Comfort.

Hurricane Florence is already affecting the coast.  National Data Buoy Center C-MAN station CLKN7 at Cape Lookout, North Carolina reported a sustained wind speed of 81 m.p.h. (131 km/h) and a wind gust of 101 m.p.h. (163 km/h).  Storm surges were already occurring along portions of the coast east of the center of Hurricane Florence where the winds were pushing water toward the coast.  The highest surge appeared to be in the area of the western part of Pamlico Sound near the mouth of the Neuse River.  There were scattered reports of wind damage and power outages.

A high pressure system over the northeastern U.S. is blocking the northward movement of Hurricane Florence.  The high is steering Florence slowly toward the northwest.  On its anticipated track Hurricane Florence will make a landfall near Wilmington, North Carolina on Friday.  Florence could move a little south of due west after landfall.  The center will pass a little north of Myrtle Beach, South Carolina and then move toward Columbia, South Carolina.  Florence is likely to continue to weaken slowly.  Because of the slow movement, many locations will experience extended periods of gusty winds.  Power outages are likely to become more widespread on Friday.  Hurricane Florence will drop locally heavy rain.  Locations where rainbands are essentially station could receive over a foot (0.3 meters) of rain.  Serious fresh water flooding is likely to develop on Friday and Saturday.

Elsewhere over the Atlantic Ocean, Tropical Storm Helene generated a Tropical Storm Watch for all of the Azores, Tropical Storm Isaac sped across the eastern Caribbean Sea and former Subtropical Storm Joyce made a transition to Tropical Storm Joyce.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Helene was located at latitude 28.6°N and longitude 36.5°W which put it about 885 miles (1425 km) southwest of the Azores.  Helene was moving toward the north at 21 m.p.h. (34 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were gusts to 80 m.p.h. (130km/h).  The minimum surface pressure was 992 mb.

At 11:00 p.m. EDT on Thursday the center of Tropical Storm Isaac was located at latitude14.9°N and longitude 64.4°W which put it about 195 miles (315 km) south of St. Croix.  Isaac was moving toward the west at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1006 mb.

At 11:00 p.m. EDT on Thursday the center of Tropical Storm Joyce was located latitude 32.9°N and longitude 44.4°W which put it about 1040 miles (1670 km) west-southwest of the Azores.  Joyce was moving toward the south-southwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1003 mb.
