The national weather ahs also issued a Freezing Fog Advisory, which is in effect until Noon Tuesday.
* Visibility: Reduced to less than a quarter of a mile at times.
* Impacts: The inversion will trap pollutants near the surface
which can impact those with respiratory conditions. Freezing fog
can produce icy conditions on surfaces resulting in hazardous
conditions for driving and walking. The fog will also reduce
visibilities so motorist should exercise caution and drive with
extreme care when encountering fog.
An Air Stagnation Advisory indicates that due to limited movement
of an air mass across the advisory area…pollution will
increase. Check with your local air quality agency for possible
