Dorian has been re-strengthening today and as of the 11PM advisory which just dropped is now once again a category 3 major hurricane, though close interaction with land now means it probably won't stay that way for very long.
Still, the hurricane is tracking due north at 7 mph; the current track will bring the center right up to the coastline before it bends and follows the shore to the northeast. South Carolina between Charleston and Myrtle Beach might experience eyewall winds from Dorian, and those areas and inland will be getting absolutely soaked by rain banding too - enough rain that Charleston might see some flooding as that's basically where that whole region drains through. Between Myrtle Beach and Charleston they'll be dealing with some storm surge flooding. And all of these problems will migrate north toward Cape Hatteras over the next couple of days as the storm moves that way.
