The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued an Air Quality Alert for July 20, 2026, for elevated levels of fine particulate due to wildfire smoke. Concentrations will linger from Unhealthy for Sensitive Groups (USG) range. This is a Statewide Air Quality Alert. 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.
