Dense Fog Advisory/Freezing Fog Possible – Slick Spots

A Dense Fog Advisory has been issued for the entire Tennessee Valley until 9:00 am this morning.  A few accidents have already been reported this morning along the I-65/I-565 interchange in Huntsville due to icy patches. Dense fog has also been reported in many locations, especially in Huntsville, Scottsboro and Fayetteville, Tennessee.  As of right now it seems like the highest concentration of freezing fog is across the central Tennessee Valley, near the I-65 corridor, as that is where temperatures have fallen below freezing.  Visibility could be reduced to less than 1/4 mile in spots.  In communities where temperatures have dropped below freezing, freezing fog is possible, with slick spots possible as the moisture freezes on surfaces.  Also lingering moisture from yesterday’s precipitation has created some patches of black ice as well.  Use extreme caution if you are heading out to early morning church services, or anywhere else. Slow down and use your low beams if you approach fog.  Below are the 5:00 am temperatures and visibility map.

The Limestone County EMA have reported that many bridges and roads are iced over due to dense freezing fog and that travel is hazardous.  Madison Public Works has also reported icy bridges and overpasses in the city of Madison. Metallic and elevated surfaces, such as bridges and overpasses are at greatest risk for icy spots.  Any fog will lift quickly after sunrise and icy spots will be mostly melted by mid to late morning.
