Canadian Wildfires Bring Health Warnings

Smoke from Canadian wildfires has prompted health warnings across the Upper Midwest and Montana for the second year in a row. Fires raging in British Columbia and Alberta have filled the skies with haze over parts of Montana, the Dakotas, Minnesota and Wisconsin on Sunday, lingering into Monday morning. Unhealthy air pollution levels mean everyone in Minnesota should stay indoors and avoid heavy exertion outdoors, the Minnesota Pollution Control Agency said in its first statewide air quality alert of the season Sunday. Scheduled to end at noon Monday, the advisory was extended until 11 p.m. for southern Minnesota including the Twin Cities metro area. The Wisconsin Department of Natural Resources said the air quality was unhealthy for sensitive people in multiple counties across the state’s northern two-thirds on Sunday.
