Air Quality Alert issued July 15 at 1:26PM EDT by NWS Northern Indiana

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Advisory for Tuesday July 15 and Wednesday July 16, for elevated levels of ozone and fine particulate (PM2.5) in parts of southwest Michigan. Pollutants within those areas are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range. The Air Quality Advisory is in effect for the following counties in southwest Michigan... Berrien and Cass Wildfire smoke may trigger elevated particulates and ozone levels. It is recommended that, when possible, you stay indoors and keep time outdoors short and avoid strenuous activities, especially those with respiratory diseases such as asthma. Recommendations to reduce pollution and potential health effects: PM 2.5: * Reduce or eliminate outdoor burning, and the use of residential wood burning devices; * Keep windows closed overnight to prevent smoke from getting indoors, and, if possible, run central air conditioning with MERV- 13 or higher rated filters. Ozone: * Using gas-powered lawn equipment; * Driving less or delaying and/or combining errands; * Refueling less or topping off when refueling.

Air Quality Alert issued July 15 at 12:03PM EDT by NWS Grand Rapids MI

Air Quality Advisory for July 16, 2025 The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Advisory for July 16 for elevated levels of ozone in several western lake shore counties. Pollutants within those areas are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range. The Air Quality Advisory is in effect for the following Michigan counties: Allegan, Kent, Muskegon, Ottawa, and Van Buren As wildfire smoke exits the region, leftover chemical precursors are present which could trigger elevated ozone levels. Original forecasts of early cloud cover during Wednesday now look less likely as projected West Michigan lake dynamics look to delay the cloud arrival. Minus the cloud coverage, elements such as wind direction, temperature, dew points, and upper air conditions all point towards the likelihood that elevated ozone concentrations, in the USG range, could occur throughout those counties. 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 ozone 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.
