The Minnesota Pollution Control Agency (MPCA) rated the air quality for most of the state as “moderate” on Sunday afternoon. It said air in areas around Hibbing, Marshall and Mankato posed a potential risk to people with breathing sensitivity.

Canadian wildfire smoke is again prompting a statewide Air Quality Alert with “unhealthy” air already across most of Minnesota according to the Pollution Control Agency. It’s also going to tie the longest stretch of unhealthy air in state history.
