Canadian Wildfire— States across the northern U.S., including Minnesota and Maine, are under air quality alerts this weekend as thick wildfire smoke from Canada drifts southward, affecting millions.
The Minnesota Pollution Control Agency (MPCA) has issued a statewide air quality alert from 11 p.m. Saturday to 11 p.m. Sunday. The Air Quality Index (AQI) is forecast to reach the orange level—unhealthy for sensitive groups, including children, seniors, and individuals with respiratory or heart conditions.
Smoke is expected to blanket Minnesota from west to east, creating hazy skies and a noticeable smoky odor. Conditions are expected to begin clearing late Sunday as winds shift.
Meanwhile, the Maine Department of Environmental Protection (DEP) issued a similar advisory. Northern Maine will remain in the unhealthy for sensitive groups category throughout the weekend, with light winds slowing the smoke’s dispersion. Southern and coastal areas are forecast to see moderate air quality levels, though ozone may briefly rise.
The Maine DEP says improvements may come Monday, but another smoke plume from wildfires in Labrador could arrive early next week. Residents are advised to monitor forecasts and limit strenuous outdoor activity, especially if they belong to vulnerable groups.
Health officials recommend:
- Staying indoors when possible
- Using air conditioning or HEPA filters to circulate clean air
- Avoiding vigorous outdoor exercise
- Keeping asthma medications and health plans ready
