...Air Quality Alert for Wednesday, July 15, 2026...
The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has issued an Air Quality Alert for July 15, 2026, for elevated
levels of fine particulate due to wildfire smoke. Pollutants within
those areas are expected to be in the Unhealthy for Sensitive Groups
with the potential for Unhealthy, especially north.
This is a Statewide Air Quality Alert
Plumes of smoke from Canadian wildfires are expected to move into the region
this week. The plumes will reach the upper peninsula this evening, sinking
into the northern lower peninsula overnight. Models are showing the
smoke plumes will reach the Michigan/Indiana border Wednesday evening.
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.
