Air Quality Alert
MIZ050-056-057-064-071-180400- Muskegon-Ottawa-Kent-Allegan-Van Buren- Including the cities of Muskegon, Grand Haven, Jenison, Grand Rapids, Holland, and South Haven 1224 PM EDT Mon Jun 16 2025 Air Quality Advisory for June 17, 2025 The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Advisory for June 17 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 All signs point towards the likely development of elevated ozone along the several lake shore counties. Elements such as wind direction, temperature, dew points, upper air conditions all point towards the likelihood that could see ozone concentration in the Unhealthy for Sensitive Groups (USG) range along those counties. Cloud cover is uncertain during the peak heating hours of the day, but enough sun will likely be present to trigger the photochemical reactions necessary to generate ozone. 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.
