...Air Quality Advisory in effect today, Thursday July 31th, through
Saturday, August 2nd...

The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has issued an Air Quality Advisory for elevated levels of
fine particulates (PM2.5) across the state of Michigan. Pollutants
are expected to be in the Unhealthy for Sensitive Groups (USG,
Orange AQI) range from Thursday until Saturday with some locations
reaching the Unhealthy (Red AQI) range.

The Air Quality Advisory is in effect for the following Michigan
counties...

Midland...Bay...Huron...Saginaw...Tuscola...Sanilac...Shiawassee...
Genesee...Lapeer...St. Clair...Livingston...Oakland...Macomb...
Washtenaw...Wayne...Lenawee and Monroe.

Smoke from Canadian wildfires remains over the state Thursday, with
PM2.5 concentrations ranging from USG to Unhealthy. Some locations,
mostly in the Lower Peninsula, may experience improvements in air
quality from late Thursday into Friday; however, that is expected to
be short-lived as additional plumes drop into the region. High
pressure settling overhead will limit dispersion and keep smoke at
the surface through the end of the week. This sustains the threat of
increased PM2.5 and readings in the USG range will continue Thursday
through Saturday, with some locations reaching as high as the
Unhealthy range.

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.
