According to the National Hurricane Center (NHC) as of 11 a.m. EDT, Dorian had returned to Category 2 intensity after re-intensifying to a Category 3 storm overnight Wednesday to Thursday as it moved north-northwestward parallel to the coast of Florida before turning northeastward and taking aim at South Carolina’s coast this morning. It was located at 32.5°N, 79.1°W with a minimum central pressure of 958 mb and maximum sustained winds of 110 mph. Dorian was moving north-northeastward with a forward speed of 8 mph. The storm’s eyewall was just offshore of the eastern coast of South Carolina.

Dorian is expected to turn northeast by tonight, then continue northeastward with a faster forward speed on Friday. The NHC forecast stated that, “On the forecast track, the center of Dorian will continue to move close to the coast of South Carolina today, and then move near or over the coast of North Carolina tonight and Friday.”

Dorian is off the coast of the Carolinas, and tropical storm conditions have already affected parts of Georgia, South Carolina, and North Carolina. Hurricane conditions are expected along parts of the South Carolina coast in the next few hours. More than 221,000 customers are without power in Georgia, South Carolina, and North Carolina this morning, the majority of which are in South Carolina. A mandatory evacuation order has been lifted in coastal Georgia. In Myrtle Beach, South Carolina, damage to some structures and vehicles has occurred and investigations are underway into a possible tornado as the cause.

A Hurricane Warning is in effect for Savannah River, North Carolina, to the North Carolina/Virginia border, as well as Pamlico and Albemarle sounds in North Carolina. According to the NHC, tropical storm conditions are spreading along the coast of North Carolina, and hurricane conditions are expected later today. In the coastal Carolinas, 6 to 12 inches of rain are expected, with isolated instances of 15 inches.

A Tropical Storm Warning is in effect for the North Carolina/Virginia border to Fenwick Island, Delaware; Chesapeake Bay from Drum Point in Maryland southward; Tidal Potomac south of Cobb Island, Maryland; and Altamaha Sound, Georgia to Savannah River, North Carolina.
