The Wisconsin DNR is recommending Wisconsinites reduce their time outdoors from Thursday into Friday due to ongoing air quality advisories resulting from Canadian wildfire smoke.
Canadian wildfire smoke will continue to impact Wisconsin’s surface air quality over the next several days. Expect widespread Unhealthy levels of PM2.5 across Wisconsin on Thursday, with values in the Very Unhealthy category possible. Conditions should slowly improve beginning Friday; however, Unhealthy for Sensitive Groups to Unhealthy levels will remain possible through the weekend.
The current advisory in effect statewide until noon on Thursday, July 31 has been extended through noon on Friday, Aug. 1. Conditions will be reevaluated on a day-to-day basis through the weekend, including updates to the forecast and any associated air quality advisories.
People with heart or lung disease, older adults and children should consider making outdoor activities shorter and less intense and reducing heavy exertion. Consider rescheduling or moving events indoors.
