Minnesota’s air quality alert, which had been slated to expire Saturday evening, has been extended to noon on Monday. Winds are still expected to shift and start driving unhealthy air north and out of the state on Saturday.

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.
