Wildfire smoke pouring into the state from Canadian fires has triggered a red air quality alert, signaling that the air is unhealthy for anyone and everyone to breath. The alert, issued by the Minnesota Pollution Control Agency, is in effect until 5 p.m. Saturday, Aug. 2, for large portions of the state, including the Minneapolis-St. Paul area.

The MPCA says that sensitive groups should avoid prolonged or heavy exertion, and everyone should limit their time spent outdoors.

Minnesota is headed for a much-needed break from the intense heat and humidity, but air quality concerns will linger over the state through the weekend.
