PRECAUTIONARY/PREPAREDNESS ACTIONS…

An Air Stagnation Advisory indicates that due to limited movement
of an air mass across the advisory area…pollution has the
potential to increase to dangerous levels. Persons with
respiratory illness should follow their physicians advice for
dealing with high levels of air pollution.

During periods of stagnant air…state air quality agencies
highly recommend that no outdoor burning occur and that
residential wood burning devices be limited as much as possible.
According to state air quality agencies…prolonged periods of
stagnant air can hold pollutants close to the ground…where
people live and breathe. Check with your local burn agency for any
current restrictions in your area.
