"The National Weather Service announced air quality alerts in 10 states Tuesday as smoke from the Canadian wildfires continues to spread across the U.S. border.

The alerts come as the Canadian Interagency Forest Fire Centre lists 746 active fires Tuesday morning, including 199 that were considered out of control. On Monday morning, 743 active fires were listed, including 298 that were out of control.

All of Wisconsin remains under air quality alert, with some parts placed under “red” alert, meaning some members of the public may experience adverse health effects; and other parts of the state are placed under “orange” alert, meaning air quality may be “unhealthy” for sensitive groups."
