...AIR QUALITY ADVISORY FOR WEDNESDAY JULY 30 AND THURSDAY JULY 31...

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 Wednesday and Thursday with some locations reaching
the Unhealthy (Red AQI) range.

The alert is in effect for the following Michigan Counties,

Keweenaw, Menominee, Dickinson, Iron, Marquette, Baraga, Northern
Houghton, Southern Schoolcraft, Ontonagon, Delta, Gogebic, Luce,
Alger, Northern Schoolcraft, and Southern Houghton.

Smoke from Canadian wildfires moved into the Upper Peninsula Tuesday
and into parts of the northern Lower Peninsula Wednesday morning.
Model show the plume continuing its southern trek across the state
with smoke expected to linger across the region through Thursday. As
the smoke moves in, PM2.5 concentrations in the Unhealthy for
Sensitive Groups (USG) range will expand south, while concentrations
of PM2.5 in the Unhealthy range are more likely across northern
areas.

It is recommended that, when possible, you avoid strenuous outdoor
activities, especially those with heart disease and respiratory
diseases such as 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, and use of residential wood burning devices.

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