...Air Quality Alert in effect for Sunday July 19th...

cancelled for the following counties: Shiawassee, Genesee, Lapeer,
St. Clair, Livingston, Oakland, Macomb, Washtenaw, Wayne, Lenawee,
and Monroe.

The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has issued an Air Quality Alert for July 19, 2026, for
elevated levels of fine particulate due to wildfire smoke. On Sunday
concentrations will range from USG across the lower peninsula to
Unhealthy in the upper peninsula.

Sunday, July 19, 2026, will be a Statewide Air Quality Alert

Smoke has improved across the southern portion of Michigan early
Saturday; however, another plume is forecast to track through the
state Saturday, lasting into Sunday. The upper peninsula will be most
affected by the smoke on Saturday with fine particulate levels
deteriorating from north to south through Saturday. Concentrations
will be high enough across northern areas to warrant an Air Quality
Alert for Saturday, and by Sunday levels will be high enough to
warrant another statewide Alert. With smoke lingering across the
state, ozone also has the potential to increase quickly.

It is recommended that, when possible, you avoid strenuous outdoor
activities, especially those with heart disease and respiratory
conditions like asthma. Watch for symptoms including wheezing,
coughing, chest tightness, dizziness, or burning in nose, throat, and
eyes. You can help reduce air pollution by limiting activities, 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.
