COLUMBIA, S.C. (WVOC/AP) - It started out as a sunny day in South Carolina, but the ground was covered with up to 4 inches of snow from the winter storm that moved through overnight.

The National Weather Service reports snowfall ranged from 4 inches at Sandy Run in Calhoun County to half an inch at Gaffney in Cherokee County.

Around the Midlands, totals ranged from 2 to 4 inches.

The Associated Press reports that as many as 10,000 power customers were without electricity at one point.

The Ravenel Bridge between Charleston and Mount Pleasant and some bridges on I-526 were closed because of ice accumulations.

The Highway Patrol reports it responded to almost 820 collisions statewide between 4 p.m. Tuesday and 4 a.m. Wednesday.

On the same day last year, troopers handled about 90 collisions.

Road conditions have improved this afternoon, especially along the interstates and primary roads.

But officials are still warning motorists about patches of “black ice,” and say travel could be risky again tonight when temperatures dip back into the teens.
