Marquette, Mich. – Air across Michigan’s Upper Peninsula is reaching unhealthy levels today as wildfire smoke from Canada continues to drift into the region, prompting an Air Quality Alert through midnight Wednesday.
According to the Michigan Department of Environment, Great Lakes, and Energy (EGLE), fine particulate matter (PM2.5) could rise into the Red AQI range, especially in areas from Marquette to Sault Ste. Marie. The alert remains in effect for all counties in the U.P. until midnight, June 4. Residents with heart conditions or respiratory issues such as asthma are urged to stay indoors and limit outdoor exertion.
Visibility may also drop in smoky zones, especially along major corridors like US-2, M-28, and I-75. Schools, hospitals, and outdoor workers are advised to take precautions. Portable air purifiers and N95 masks can help reduce indoor exposure.
This is one of several air quality alerts issued this year due to ongoing Canadian wildfires, which have impacted the Great Lakes region repeatedly since spring.
The alert remains in place through Wednesday night. More advisories could follow if smoke concentrations persist.
