Lingering Wildfire Smoke Prompts Statewide Air Quality Alert In Minnesota

Lingering Wildfire Smoke Prompts Statewide Air Quality Alert In Minnesota

MINNEAPOLIS, MN – July 31, 2025 — After a turbulent start to the week marked by severe thunderstorms and damaging winds, Minnesotans are now facing a different kind of threat: persistent and widespread air pollution driven by wildfire smoke. A dense haze has blanketed the state, prompting health officials to issue an extended Air Quality Alert that remains in effect through at least Saturday, August 2, for all of Minnesota and parts of Western Wisconsin.

The culprit behind the lingering haze is a thick plume of Canadian wildfire smoke trapped in the upper atmosphere and pushed into the region by persistent northeasterly winds. A particularly heavy concentration of smoke remains stalled over Lake Superior, and forecasters warn that continued wind patterns could drive more smoke inland, further deteriorating air quality across northeastern and central Minnesota.

According to the Minnesota Pollution Control Agency (MPCA), the Air Quality Index (AQI) has reached levels classified as “unhealthy for all populations,” meaning even healthy individuals could experience adverse health effects. Vulnerable groups—including children, older adults, and people with respiratory or cardiovascular conditions—are urged to stay indoors and limit strenuous outdoor activities.

“This isn’t just a concern for people with asthma or heart issues anymore,” said MPCA meteorologist David Brown. “The current smoke levels are high enough that everyone should take precautions, especially during outdoor exertion.”

Despite the concerning air conditions, the upcoming forecast holds some silver linings. Mostly sunny, dry, and seasonably warm weather is expected through the weekend, with temperatures hovering in the mid-70s to low 80s across much of the state. However, the smoke is likely to persist, keeping skies hazy and limiting visibility in some areas.

Looking ahead, forecasters with the National Weather Service say there’s a chance for isolated thunderstorms to return early next week, which could help improve air quality depending on wind shifts and potential precipitation. For now, however, residents should plan for continued hazy skies and prioritize indoor activities when possible.

What You Can Do:

• Stay indoors as much as possible, especially during peak smoke hours (typically morning and evening).
• Use HEPA air purifiers or central air conditioning with clean filters.
• Avoid strenuous outdoor exercise.
• Keep an eye on air quality updates at www.mn.gov/air or through local weather apps.

Residents are encouraged to check on neighbors—especially the elderly or those without access to air conditioning or proper ventilation systems—and remain cautious until conditions improve.
