An historic January storm dumped more deep snow along the U.S. Gulf Coast on Wednesday after bringing Houston and New Orleans to a near standstill over the past two days and burying parts of Florida's Panhandle with accumulations more typical of Chicago.

The heaviest snowfall in the Sunshine State occurred around Pensacola, where spotters reported measuring amounts of 5 to 12 inches through Tuesday evening. Due to the hazardous weather and a series of crashes, a nearly 70-mile stretch of Interstate 10 was shut down by the Florida Highway Patrol.

A major winter storm that slammed Texas and the northern Gulf Coast is spreading heavy snow, sleet and freezing rain across parts of the Florida panhandle and eastern Carolinas.
