Minnesota Pollution Control Agency

Minnesota usually sees only two to three of these warnings each year, but we've now experienced 25 of them this year-- and it's only mid-July.

Minnesota has already set a record for the number of days with poor air quality, and persistent wildfires over Canada will mean episodes of thick smoke the rest of the summer.

It has also made "several corrective actions."

Conditions may improve today but return for the weekend.

The Minnesota Pollution Control Agency has issued an air quality alert that covers most of the state.

It's not just from fireworks!
