A rare winter storm is sweeping across the U.S. Gulf Coast.
Heavy snow, sleet and ice are making travel conditions hazardous throughout an area stretching from Houston to the Florida Panhandle.
The governors of Louisiana, Mississippi, Alabama, Georgia and Florida all declared states of emergency as snow began to accumulate in rare places.
Thick coats blanketed New Orleans' French Quarter, and blizzard warnings were issued for Lake Charles and Lafayette, Louisiana. The state has closed bridges and major sections of Interstate 10.
Officials in the southern Gulf region urged people to shelter in place and prepare for possible power and water outages.
Thousands of flights were canceled due to icy runways and limited visibility. Schools and colleges are closed.
Forecasters predict record snowfall levels across much of the region.
Let's take a look.
