Freezing fog could be an issue for some in Alabama this morning.

The National Weather Service has issued a freezing fog advisory for several central Alabama counties, and the weather service is also cautioning those in north Alabama to be on the lookout.

The weather service said fog could reduce visibilities to a quarter-mile or less. It’s also cold enough that the fog could freeze on some surfaces, causing slick spots on bridges or other elevated areas.

The freezing fog advisory will be in effect until 8 a.m. Thursday for the following counties: Etowah, Calhoun, Cherokee, Cleburne, Shelby, St. Clair, Talladega, Clay, Perry, Bibb, Chilton, Coosa, Dallas, Autauga, Lowndes, Elmore and Montgomery.

Patchy freezing fog will also be possible in north Alabama. The weather service in Huntsville issued a special weather statement for the north Alabama counties of Lauderdale, Colbert, Franklin, Lawrence, Limestone, Madison, Morgan, Marshall, Jackson, DeKalb and Cullman.

Forcaters said patchy dense freezing fog had developed on Thursday morning in some low-lying areas, especially near the Tennessee River and other waterways or lakes in the region.

The weather service advised drivers in those areas to slow down, use their headlights and leave plenty of distance ahead of them. Also, they should be on alert for frost on bridge decks.
