A tornado watch means conditions are favorable for the formation of a tornado. If an actual tornado is spotted, a tornado warning would be declared for that area.
The watch also includes Aiken, Bamberg, Barnwell, Calhoun, Chesterfield, Clarendon, Darlington, Dillon, Florence, Horry, Kershaw, Lee, Lexington, Marion, Marlboro, Orangeburg, Richland, Saluda and Sumter Counties.
The watch comes as remnants of Sally move across South Carolina.
The Live 5 Weather team declared Thursday a First Alert Weather Day because of expected periods of heavy rain, the potential for flooding, and a chance of tornadoes.
