Tornado watches have been issued across South Carolina as the state takes a drenching from heavy rains.
The National Weather Service says 22 of the state's 46 counties were under a tornado watch Wednesday afternoon. The watch area extends from the state's western border all the way to the coast and as far north as Camden.
Earlier Wednesday, rains swamped the coastline at high tide, snarling Charleston rush hour traffic and flooding intersections. National Weather Service forecaster Douglas Berry says a cold front moving through the state carries the potential for strong storms and hail between Columbia and the coast.
A high surf advisory is in effect through Thursday morning on the state's south coast. Forecasters say waves as high has 6 feet could break on the beaches.
