... Dense fog advisory remains in effect until 3 PM CST Monday...
Areas of dense fog will become more widespread tonight... especially in the higher terrain from the twin ports area... north along the North Shore of Lake Superior. The visibility was a quarter mile at the Cook County Airport in Grand Marais. Visibilities will drop to a quarter mile or less at times. Interstate 35... as well as portions of highways 53 and 61 will be impacted by the fog.
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.
