The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for the southern half of Minnesota effective Friday, Aug. 17 beginning at 8 p.m. through Sunday, August 19 12 p.m. This is in addition to the air quality alert already in effect for the northern half of the state. The affected area includes the Twin Cities metro area, Mankato, Rochester, and St. Cloud and the tribal nations of Upper Sioux and Prairie Island.
Canadian wildfire smoke coming from British Columbia, Alberta, and western Ontario will continue to affect most all of Minnesota Friday afternoon and evening as it moves from north to south across the state. Air pollution monitors show a rapid rise in fine particles with values approaching an Air Quality Index (AQI) value of 101 (Orange).
This plume of smoke over northern Minnesota is expected to move south during the day. Waves of smoke will move over the state with air quality beginning to be impacted in the St. Cloud to Twin Cities area by Saturday morning and Mankato and Rochester by the afternoon hours. Periods of smoke are expected to persist in this area through Sunday morning.
During this time, fine particle pollution is expected to remain at, or above, a level that is considered unhealthy for sensitive groups. By Sunday afternoon winds will switch to the south improving air quality conditions.
