... Dense fog advisory in effect until 3 PM CST Monday...

The National Weather Service in Duluth has issued a dense fog
advisory... which is in effect until 3 PM CST Monday.

Fog... some dense... will continue from the twin ports area... north
along the North Shore of Lake Superior. This afternoon... the fog
will be most dense in the higher terrain just inland from Lake
Superior. 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. The fog will become more widespread
tonight.

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.
