The Michigan Department of Environmental Quality has extended the ongoing Air Quality Advisory through Monday August 4, for elevated levels of fine particulates (PM2.5). Pollutants are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range with some areas reaching Unhealthy (Red AQI) range. The alert is in effect for all Michigan counties. Wildfire smoke looks to persist throughout Michigan through at least Monday as winds shift, although it stays rather light. Overall hourly concentrations look to diminish but still stay in the USG range, therefore above our Advisory criteria. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases such as 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, and 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.
