Full Notification

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Advisory for June 21 and June 22, 2025, for elevated levels of ozone in western counties of Michigan. Pollutants within those areas are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range. The Air Quality Advisory for Saturday and Sunday is in effect for the following Michigan counties: Allegan, Kent, Muskegon, Ottawa, and Van Buren We are in the peak of ozone season, and the current forecast shows ozone-conducive conditions for Saturday and Sunday. Surface temperatures in the 90s, coupled with ample sunlight and southwest winds, create an environment favorable for ozone development along the Lake Michigan shoreline. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with respiratory diseases such as asthma. People and businesses are urged to avoid activities which can lead to zone formation. These activities include: refueling vehicles or topping off when refueling; using gasoline powered lawn equipment; using charcoal lighter fluid. Positive activities include: driving less; telecommuting; walking or bike riding; delaying or combining errands; using water-based paints.
