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.
People with respiratory illness should follow their physician's
advice for dealing with high levels of air pollution during periods
of stagnant air, especially if an Air Quality Alert is in effect for
your area. To see if an Air Quality Alert is in effect for your
area, go to www.weather.gov/pqr and left-click your location on the
homepage map display. Alternatively, you could also type your
location into the search bar found on the top-left hand side of the
homepage. From there, you will see an Air Quality Alert listed at
the top if one is in effect for your location; you can click the
alert to read more details if applicable.
If driving, slow down and leave plenty of distance ahead of you.
Pedestrians and cyclists should wear bright or reflective clothing
to increase the chances of being seen by others in poor visibility
conditions.
