People will see an elevated risk of a tornado Thursday as a cold front sweeps through the Lowcountry and spawns showers and thunderstorms, according to updated predictions from the National Weather Service.
The Storm Prediction Center, a Weather Service facility in Oklahoma that predicts the potential for severe weather, released a map Thursday that showed a 10 percent chance of a tornado for the northern coastal areas of South Carolina.
Charleston was in the southern portion of the area of heightened risk. The rest of the Lowcountry, the Midlands and part of the Upstate will see a 2 percent to 5 percent chance of a twister.
Offshore, waterspouts also are possible.
Some areas also could get nearly 3 inches in the system.
Forecasters expected the weather to deteriorate in the Charleston area after 11 a.m. Thursday. Showers are likely, and storms are possible.
They’ll bring between 1 and 2 inches of rain.
Meteorologists at the Weather Service station in North Charleston said the chance of rainfall will be 100 percent Thursday night. The threat will linger until 2 a.m. Friday.
Another half inch to three quarters of an inch will be possible overnight.
