The National Weather Service in Huntsville has issued a Dense Fog Advisory through 8 a.m. due to visibility issues for motorists traveling through thick areas of fog.
Be sure to drive more cautiously — slow down, and provide more space between your own vehicle and the one in front of you.
In addition, use the low beam headlights, as high beams scatter the light which makes it harder to see further ahead.
Below is additional information from the National Weather Service.
