Interstate 10 from the Alabama/Florida state line almost to Tallahassee has been closed since Wednesday evening. Conditions have now improved.

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.

Around 40 million people in the U.S. are under a winter storm warning from an unusual blast of severe cold weather and snow across the South.
