Canada is battling more than 700 active wildfires across the country, roughly two-thirds of which are burning out of control, according to the Canadian Interagency Forest Fire Center (CIFFC). Smoke billowing from the blazes has blanketed central Canada and the northern U.S., prompting widespread air quality alerts.

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.
