...AIR QUALITY ALERT THROUGH SUNDAY JULY 19...
The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has issued an Air Quality Alert for July 18 and July 19, 2026,
for elevated levels of fine particulate due to wildfire smoke.
Concentrations on Saturday will range from Unhealthy for Sensitive
Groups (USG) in northern half of the lower peninsula to Unhealthy
across the upper peninsula. On Sunday concentrations will range from
USG across the lower peninsula to Unhealthy in the upper peninsula.
Saturday, July 18, 2026, Air Quality Alert covers the upper
peninsula, and the northern half of the lower 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.

...AIR QUALITY ALERT REMAINS IN EFFECT UNTIL 11 AM CDT MONDAY...
* WHAT...The Minnesota Pollution Control Agency has issued an Air
Quality Alert for fine particles pollution. The Air Quality
Index (AQI) is expected to reach the Maroon or Hazardous
category.
* WHERE...Northeast Minnesota.
* WHEN...Until 11 AM CDT Monday.
* IMPACTS...Everyone is more likely to be affected.
* ADDITIONAL DETAILS...Heavy smoke is expected to persist across
much of northeastern Minnesota through the weekend and into
Monday. A separate area of heavy smoke will move across
northwestern Minnesota this morning and afternoon. Northwestern
Minnesota should see improved air quality by this evening.
Additional heavy smoke may move south from Canada this weekend,
and the air quality alert may need to be extended into east
central and southeastern Minnesota.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Sensitive groups, such as people with lung disease (including
asthma), heart disease, and children and older adults, should
remain indoors and keep activity levels low. The general public
should avoid all physical activities outdoors. Reduce or eliminate
activities that contribute to air pollution, such as outdoor
burning, and use of residential wood burning devices. Reduce
vehicle trips and vehicle idling as much as possible. Keep windows
closed overnight to prevent smoke from getting indoors.
