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.

The Minnesota Pollution Control Agency (MPCA) has issued an AIR QUALITY ALERT for all of Minnesota until late Saturday afternoon. Meanwhile, the Iowa DNR has issued an AIR QUALITY ALERT for all of Iowa through Friday night.
