The National Hurricane Center continues to track Hurricane Dorian as it lifts northwest away from Puerto Rico, according to the National Weather Service. Dorian is expected to continue moving northwest for the next couple of days, then turn more west-northwest toward Florida and the Southeast U.S. this weekend, likely strengthening into a major hurricane. It is too soon to know if there will be any direct impacts from Dorian for the Georgia Coastal Empire and South Carolina Lowcountry. However, moderate to major levels of tidal flooding are expected through at least the middle of next week, even if Dorian remains well away from the area. In addition, the threat for heavy rainfall-induced freshwater flooding will also increase early next week.
There is a Coastal Flood Watch for all coastal counties in effect from 6 p.m. to midnight tonight.
Expect moderate to major coastal flooding with the evening high tide. Some flooding of coastal roads is likely, especially around downtown Charleston and on barrier islands. Water could also approach or enter some structures. Some flooding along Highway 80 to Tybee Island is also possible. The risk for major flooding could persist into Sunday.
The potential for heavy rainfall and flooding of streets and roadways will be increasing early next week, especially if Dorian tracks closer to our area.
The potential for dangerous surf, rip currents, and beach erosion will be increasing, especially by later this weekend.
The National Weather Service will issue an update at noon today.
