Will Minnesota issue another air-quality alert before Friday, August 7?

Minnesota issued another air-quality alert due to wildfire smoke before Friday, August 7, 2026, continuing a summer marked by unusually frequent smoke events. The Minnesota Pollution Control Agency issued a statewide alert effective Tuesday, July 29, that remained in effect through midday Monday, August 4, as fine particle pollution from wildfires burning in Canada and northern Minnesota was forecast to reach the red Air Quality Index category, unhealthy for all groups. KARE 11 separately reported additional MPCA alerts covering much of the state during the same stretch as AQI readings pushed into the red category in multiple regions. The alerts capped a summer in which MPCA meteorologists had forecast 12 to 16 days of wildfire-smoke impact statewide, driven by hundreds of active fires in Canada and more than a dozen burning in northern Minnesota, including three inside the Boundary Waters Canoe Area Wilderness. The recurring alerts prompted health warnings for children, older adults and people with asthma or chronic obstructive pulmonary disease. The community's 100% Yes forecast proved correct, reflecting near-certainty given the persistent smoke pattern already well established earlier in the summer.
