...AIR QUALITY ADVISORY THROUGH TUESDAY AUGUST 5TH...

The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) is continuing an Air Quality Advisory for elevated levels of
fine particulate (PM2.5) through Tuesday August 5th. Pollutants
within those areas are expected to be in the Unhealthy for Sensitive
Groups (USG, Orange AQI) range.

The Air Quality Advisory includes all Michigan counties.

Smoke from Canadian wildfires remains trapped under a high pressure
system through Tuesday. As the high pressure system slowly moves
east of Michigan, it is expected that air quality will improve on
Wednesday.

It is recommended that, when possible, you avoid strenuous outdoor
activities, especially those with heart disease and respiratory
diseases like asthma. Monitor for symptoms such as wheezing,
coughing, chest tightness, dizziness, or burning in nose, throat,
and eyes.

Reduce or eliminate activities that contribute to air pollution,
such as:
 * outdoor burning,
 * use of residential wood burning devices.

Tips for households: Keep windows closed overnight to prevent smoke
from getting indoors and, if possible, run central air conditioning
with MERV-13 or higher rated filters.
