WEATHER ALERT - Worst of thunderstorms over, wind and some rain to continue

A storm with high winds moved through Mount Pleasant and the Lowcountry on Tuesday morning April 5, 2011.

A severe thunderstorm rolled over the Lowcountry this morning, downing trees and power lines in some areas.

Lightning continues to streak across the sky but the worst of the thunderstorms have passed.

A severe thunderstorm warning expired at 6:30 a.m. A tornado watch remains in effect until 10 a.m. and a high surf advisory and a wind advisory are in effect until noon.

No flooding is expected, according to Joe Calderone, meteorologist at the National Weather Service in Charleston. He said most areas received at most a half-inch of rain.

High winds and driving rain slowed the morning commute on Interstate 26. Motorists are urged to use caution. There are multiple reports of downed trees and malfunctioning traffic lights.

Calderone said some areas may still see rain before noon today. The skies are expected to clear after that, with a high near 70 degrees.

Across South Carolina, the line of severe storms passing through has knocked down power lines and trees along its path. Some areas reported hail but there were no reports of it in the tri-county region.

No serious injuries or deaths have been reported from the storms, which marched across the state before dawn Tuesday.

Trees were reported down in nearly every county along the storm’s path, with several falling on homes. The National Weather Service says a wind gust of 66 mph was measured on Lake Murray as one storm came through.

The Highway Patrol reported hundreds of incidents, many of them trees blocking roads or broken traffic lights.

South Carolina Electric and Gas reports about 50,000 power outages, most of them in Lexington and Richland counties. Duke Power reports nearly 10,000 customers without electricity, mostly along Interstate 85.
