Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued an Air Quality Alert for July 15 and July 16, 2026, for elevated levels of fine particulate due to wildfire smoke. Pollutants within those areas are expected to range from Unhealthy for Sensitive Groups in the south to Unhealthy in the north. Hourly concentrations at times may reach Very Unhealthy to Hazardous.
This is a Statewide Air Quality Alert.
Plumes of smoke from Canadian wildfires will continue moving into the region this week. The plumes Wednesday morning have reached the upper peninsula, and the plumes will continue sinking south, reaching 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.
