UPDATE: The tornado watch has been dropped; however, a severe thunderstorm watch remains active for Georgetown and Williamsburg counties. Rain and some wind will continue into the afternoon. — CHARLESTON, S.C. (WCBD) – A tornado watch is active for a large portion of South Carolina on Sunday, including much of the Lowcountry region. A strong line of storms associated with a cold front will sweep across the state, bringing a risk for severe thunderstorms, gusty winds, and a chance for isolated tornadoes. The greatest impacts would likely be felt between 9 a.m. and 3 p.m. “We are tracking a line of strong to severe thunderstorms moving quickly through Georgia, which will be moving into SC this AM.  Our timeline for storms has now moved up to late morning into the early afternoon. Severe Thunderstorms are possible, with an isolated tornado, especially closer to Interstate 95,” said Storm Team 2 Chief Meteorologist Rob Fowler. Much of the area should plan for damaging wind gusts in excess of 60 mph, and isolated tornadoes, especially inland from coastal counties. “We are hoping the storms continue moving quickly, which could limit severe potential. Be alert for rapidly changing conditions later this morning away from the coast, and early to midafternoon along the coast,” Fowler added. The tornado watch is active for Collecton, Charleston, Berkeley and Dorchester Counties until 1 p.m. The National Weather Service also issued a severe thunderstorm watch for Georgetown and Williamsburg Counties until 5 p.m. Count on 2 for updates and download the News 2 apps for weather alerts and updates.
