Cloquet, Minnesota

... 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.
