Be careful on the roads today if you’re in north Alabama.

The National Weather Service in Huntsville has issued a winter weather advisory for all of its north Alabama counties. It will be in effect until 7 p.m. Monday.

The weather service said up to 1 inch of snow will be possible, and any leftover rainfall could freeze on roads, making for dangerous driving conditions.

Forecasters said those in north Alabama should “plan on slippery road conditions where fallen precipitation refreezes into the afternoon hours. The hazardous conditions could impact the Monday evening commute.”

The counties in the advisory are Lauderdale, Colbert, Franklin, Lawrence, Limestone, Madison, Morgan, Marshall, Jackson, DeKalb and Cullman.
