Major disruptions are expected throughout Wednesday as the Gulf Coast continues to battle with a rare winter storm.

The storm prompted the first-ever blizzard warnings for several coastal counties near the Texas-Louisiana border, and snowplows were at the ready in the Florida Panhandle.

As heavy snow, sleet and freezing rain hit parts of the Deep South, a blast of Arctic air plunged much of the Midwest and the eastern U.S. into a deep freeze.
