Air Quality Alert
Issued: 4:35 PM Jul. 14, 2025 – National Weather Service
...Air Quality Alert remains in effect for today, Monday July
14th...

The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has issued an Air Quality Alert for elevated levels of fine
particulate (PM2.5) that remains in effect through Midnight.
Pollutants across the state are expected to reach the Unhealthy (Red
AQI) to USG (Orange AQI) range in northern locations, with ranges of
USG to Moderate further south.

The Air Quality Alert today is statewide.

Plumes of wildfire smoke will continue to track across Michigan
today. Highest fine particulate concentrations will be seen in
northern areas with periods of Unhealthy AQI possible. Central
locations could see readings ranging from Unhealthy to USG, and
southern locations can expect levels of fine particulate in the
Moderate to USG 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.
