All Midlands districts will be closed Thursday.
Lexington County districts, Richland 1 and Richland 2, and Kershaw County are cancelling classes and closing offices.
Kershaw County superintendent Frank Morgan said Wednesday he is already fielding questions about Friday school closure, although that decision won't come until he and his operations manager survey roads Thursday.
"I have parents Facebooking me every 20 minutes about Friday, which is OK," he laughed.
But he said these ongoing storms require a look at many factors, including the conditions on rural roads and parking lots as well as main thoroughfares.
"The other thing we are watching is electricity," Morgan said. "That is still a danger for us. If the schools lose electricity then you have to start dealing with kitchens."
"What we have heard is this isn't going to stop until Thursday morning," he said. "Tomorrow we will get a preliminary look and just get a handle on where we are."
