... Dense fog advisory remains in effect until 3 PM CST Monday...
Precautionary/preparedness actions...
A dense fog advisory means visibilities will be reduced to less than a quarter mile in some locations. Rapid changes in visibility from a few miles to only a few hundred feet may occur over very short distances. If you are driving... slow down... use low beam headlights and be prepared for the sudden loss of visibility as you enter fog banks. Many deadly accidents happen in instances where dense fog is not widespread... but where rapid changes in visibility occur and drivers suddenly cannot see as they drive into a dense fog bank.
