The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for all of southern Minnesota until Thursday, June 29, at midnight. 

Smoke from wildfires in Ontario and Quebec moved into eastern and southern Minn. late Monday. As a result, ground-level smoke is expected to linger across the alert area on Tuesday. However, the smoke currently impacting Wisconsin is expected to recirculate into southern Minn., and ground-level smoke is expected to persist across southern and east central Minn. on Wednesday. A cold front will move across Minn. on Wednesday afternoon and bring cleaner air from the west. Air quality should improve statewide by midnight on Thursday.

Fine particle levels are expected to reach the orange air quality index category, a level considered unhealthy for sensitive groups, across southern, east central, and northeast Minn. In the orange area, sensitive groups should limit prolonged or heavy exertion and time spent outdoors.
