Freezing rain and sleet have closed schools and offices and caused hundreds of wrecks across North Carolina, Tennessee and Kentucky.
The icy weather snarled traffic across much of western and central North Carolina. The Department of Transportation reported traffic moving under 30 mph on much of Interstate 40 from Winston-Salem to Raleigh and Interstate 85 from Charlotte to Durham.
Charlotte Police were responding to dozens of calls of cars overturned as the heaviest freezing rain moved through.
The storm has caused no deaths, and only scattered power outages have been reported.
Tennessee had declared a state of emergency as a precaution and the eastern part of the state is seeing significant icing.
An ice storm warning was issued from the Smoky Mountains, northward through Knoxville, Cumberland Gap and well into Kentucky.
