The state of Minnesota is entering another in a long string of summer days marred by air quality alerts. Poor air quality will continue through Saturday with lingering wildfire smoke from Canada.

An air quality advisory has been issued for the Adirondacks for the second weekend in a row as wildfires in Canada continue to burn.

The Air Quality Index (AQI), a system used to communicate how much pollution is in the air, is expected to reach the red or unhealthy category in a large swath of Minnesota, and will likely remain so through Saturday.
