Weather Alerts and Warnings for Dearborn

Air Quality Alert

Air Quality Alert issued July 19 at 9:11AM EDT by NWS Detroit/Pontiac MI
Jul 19, 9:11 AM Jul 20, 12:30 PM
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has
issued an Air Quality Alert for July 19 and July 20, 2026, for elevated
levels of fine particulate due to wildfire smoke. Concentrations on
Sunday will range from Unhealthy for Sensitive Groups (USG) in the lower
peninsula to Unhealthy across the upper peninsula. On Monday USG
concentrations are expected statewide.

This is a Statewide Air Quality Alert.

Another smoke plume has settled over the region due to wildfires in Canada.
The highest levels of fine particulate will be across the upper peninsula
on Sunday. We expect the increased pollution to continue into Monday;
however, levels will improve during the day as our winds shift to a
southerly direction. 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.
