Minnesota Wildfires Scorch Nearly 69,000 Acres as Air Quality Alerts Blanket Upper Midwest
Wildfires across northeastern Minnesota have burned nearly 69,000 acres as of July 20, 2026, sending smoke across the Midwest and triggering air quality alerts across multiple states. Fire crews continue containment efforts while hot, dry weather and gusty winds present ongoing challenges.
Massive Fire Acreage
Wildfires burning across northeastern Minnesota have now scorched nearly 69,000 acres, according to the latest infrared mapping; fire crews continue to build containment lines, protect homes, and monitor several fires where activity has slowed. The fires represent one of the largest wildfire events to impact the region in recent years.
Environmental and Health Concerns
Wildfire smoke continues to affect Minnesota today, with an Air Quality Alert remaining in effect until 11 a.m. for the Twin Cities and much of eastern and southern Minnesota. The Minnesota Pollution Control Agency says air quality is expected to reach unhealthy levels before conditions gradually improve later today. A Heat Advisory is in effect from noon until 6 p.m. for much of central and southern Minnesota, with heat index values climbing into the mid-90s.
Evacuation and Access Restrictions
Evacuation orders remain in effect in parts of Lake, St. Louis and Cook counties, while the Boundary Waters remains closed; officials are reminding the public to obey closures, avoid flying drones near fires and stay away from lakes where firefighting aircraft are operating.
Tourism and Economic Impact
Minnesota tourism officials say wildfire smoke and the temporary closure of the Boundary Waters Canoe Area Wilderness are creating uncertainty during the peak summer travel season. Enhanced burning restrictions are being implemented across affected counties as fire danger remains elevated.
