Now
From Today 09:32 (10 hours ago)
Until Tomorrow 12:15 (16 hours from now)
Official warning explanations:

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) continues the Air Quality Alert for today and extended the Alert through Friday July 17, 2026, for elevated levels of fine particulate due to wildfire smoke. Pollutants are expected to range from Very Unhealthy to Hazardous.

This is a Statewide Air Quality Alert.

Plumes of smoke from Canadian wildfires continue to drift across the region today. Elevated fine particulates due to the smoke will continue through Friday.

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 and 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.

Official warning explanations:

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has update the Air Quality Alert. It remains in effect for today through Friday July 17, 2026, for elevated levels of fine particulate due to wildfire smoke. Concentrations will be in the Hazardous range for all areas.

This is a Statewide Air Quality Alert.

Plumes of smoke from Canadian wildfires continue to drift across the region. Elevated fine particulate due to the smoke will continue through Friday.

Everyone should seek cleaner air indoors and keep activity levels low. While indoors, take action to improve the indoor air quality such as: closing windows and minimize opening of doors, if HVAC systems are not equipped with MERV-13 filters or higher, use portable air cleaners, avoid activities that make indoor air quality worse: burning candles, using vacuums without a HEPA filter, using gas stoves more than necessary, smoking, spraying aerosol products.

If you must be outdoors for short periods of time: Wear an N95 or P100 respirator marked with NIOSH. The respirator should fit tightly, collapse as you breathe in and not let air in from the sides. Instructions for fitting a respirator mask properly can be found at: https://www.epa.gov/sites/default/files/2018-11/documents/respiratory_protection- no-niosh-5081.pdf
