Minneapolis, Minnesota – Smoke from Canadian wildfires is set to send air quality plummeting across central and southern Minnesota from midnight Thursday until 11 p.m. Friday, putting millions at risk as the Air Quality Index is expected to reach the Red (Unhealthy) category.
According to the Minnesota Pollution Control Agency, a thick band of wildfire smoke from Saskatchewan and Manitoba will surge south, spreading into the Twin Cities, St. Cloud, and Mankato by Thursday morning. By Thursday afternoon, smoke will blanket much of east central and south central Minnesota, including Albert Lea, Alexandria, Apple Valley, and Stillwater. Some uncertainty remains on how far south the heaviest smoke will reach, but health officials warn that anyone—especially children, older adults, and those with asthma or heart disease—should avoid heavy outdoor activity and keep windows closed overnight.
Sensitive groups are urged to stay indoors, use air purifiers if available, and avoid burning wood or idling vehicles. If you need to travel, limit time outdoors and use N95 masks for added protection. Schools and child care centers in affected areas should consider limiting recess or outdoor events. The Minnesota Department of Transportation may issue additional advisories for outdoor workers and drivers if visibility drops.
Smoke is expected to linger through most of Friday, with gradual improvement from south to north as winds shift by late afternoon. Additional air quality alerts could be issued if conditions persist.
