Minnesota Braces for Unhealthy Air as Wildfire Smoke Envelops the State (July 18–20)

The Minnesota Pollution Control Agency issued an air quality alert from 2 p.m. Saturday, July 18, to 2 p.m. Monday, July 20, as wildfire smoke drives the region into the red category (unhealthy for everyone). The alert covers east central, southeast, south central, and northeast Minnesota, with affected cities including Albert Lea, Rochester, Duluth, and more. Residents should limit outdoor activity and watch for symptoms; sensitive groups may face more serious health effects. Northeast Minnesota may see improving air Sunday afternoon, but some areas near the fires and along Lake Superior could remain hazy through Monday. The fires, triggered by a July 6 dry thunderstorm, have burned over 70,000 acres, and response resources have been deployed.
