Duluth, Minn. – Wildfire smoke drifting from southeastern Manitoba is expected to reduce air quality across northern Minnesota through the Memorial Day weekend, prompting health cautions for residents from Roseau to Duluth.
According to the Minnesota Pollution Control Agency, light to moderate smoke levels will move into the region starting Friday evening, with the highest concentrations lingering through Sunday. While conditions may not meet Air Quality Alert thresholds, sensitive groups—including children, older adults, and people with respiratory issues—are urged to limit outdoor activity and consider using filtered masks.
Communities including Bemidji, Hibbing, and International Falls may notice haze and the smell of smoke, especially during overnight and early morning hours. Residents are advised to keep windows closed and run air purifiers if possible. Outdoor plans for Memorial Day celebrations may need adjustment due to reduced air quality and visibility.
Southerly winds developing Monday are expected to push smoke back into Canada, offering some relief by late Memorial Day. Officials recommend monitoring updates at https://pca.state.mn.us/air as conditions evolve.
