The shifting winds and the ongoing Canadian wildfires may force you to change your plans early this week.

The Wisconsin Department of Natural Resources issued another air quality advisory for much of the state including Door and Kewaunee counties. Five southwestern Wisconsin counties which include the cities of Platteville, Mineral Point, and Prairie du Chien are exempt from the advisory. The advisory places the other 67 counties at an orange level, which means the air is unhealthy for sensitive groups such as people with heart or lung disease, older adults, and children. Those groups should reconsider if they are planning for periods of prolonged or heavy exertion. The smoke is not expected to get as bad as it did last month when events had to be canceled due to poor air quality.

The air quality alert is expected to last until noon on Tuesday. Don’t expect the air quality alerts to disappear anytime soon.

According to the Canadian Interagency Forest Fire Centre Monday morning, there are over 1,000 active fires in Canada, 683 of which are considered to be out of control. More than 11.6 million hectares have burned as a result of forest fires in Canada.
