After a record stretch of poor air quality, parts of Minnesota will again face another air quality alert starting Tuesday morning due to wildfire smoke.

The Minnesota Pollution Control Agency issued a new air quality alert for northeast Minnesota due to the wildfires burning in Canada.

Skies over much of Minnesota looked clearer and smelled cleaner Sunday as the most troublesome air from Canadian wildfires moved east into Wisconsin. But state and federal air quality monitors still say an area of unhealthy air for people with sensitivity could resurface Monday.
