Last week, Canadian wildfire smoke blanketed Wisconsin and caused the Air Quality Index to reach the unhealthy level for sensitive groups. Six days later, on July 31, the smoke appears to have a worse impact on the air.

The Wisconsin Department of Natural Resources (DNR) is recommending Wisconsinites reduce their time outdoors Thursday, July 31 and into Friday, Aug. 1 due to ongoing air quality advisories resulting from Canadian wildfire smoke.
