Air Quality Alert Message Relayed by National Weather Service Grand Rapids MI 842 AM EDT Wed Jul 30 2025 Air Quality Advisory for Michigan Wednesday July 30th and Thursday July 31st The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued an Air Quality Advisory for elevated levels of fine particulate (PM2.5) across the state of Michigan. Pollutants across the state are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range Wednesday and Thursday with some locations reaching the Unhealthy (Red AQI) range. The Air Quality Advisory includes all Michigan counties. Smoke from Canadian wildfires moved into the Upper Peninsula Tuesday and into parts of the northern Lower Peninsula Wednesday morning. Models show the plume continuing its southern trek across the state with smoke expected to linger across the region through Thursday. As the smoke moves in, PM2.5 concentrations in the Unhealthy for Sensitive Groups (USG) range will expand south, while concentrations of PM2.5 in the Unhealthy range are more likely across northern areas. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases like asthma. Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes. Reduce or eliminate activities that contribute to air pollution, 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.
