The Minnesota Pollution Control Agency extended an air quality alert for southeastern and northern Minnesota on Tuesday due to lingering ground-level smoke from the wildfires in Canada.

The return of wildfire smoke from fires burning in Canada has sparked another air quality alert in Minnesota, which will be in effect through Tuesday. The Minnesota Pollution Control Agency has placed the northern two-thirds of the state in the red alert zone, which means "unhealthy" for all residents, through 9 a.m. Tuesday.

Minnesota's air quality is suffering due to smoke from Canadian wildfires, affecting residents statewide with alerts in place until at least Saturday.
