More than 800 Canadian wildfires burning as air quality alerts extend to US
Over 800 wildfires are currently burning across Canada, with the majority out of control. These fires are generating significant smoke plumes, causing hazardous air quality alerts to extend into multiple US states, including Michigan, Minneapolis, and Minnesota. The US Air Quality Index program has deemed air quality in these regions "hazardous," advising residents to stay indoors. Air quality alerts from the NOAA span the Upper Midwest, Great Lakes region, and the US Northeast. Fires in western Ontario are a primary source of the smoke affecting cities like Thunder Bay and Toronto, with some smoke drifting over the Great Lakes and New York. While thunderstorms are expected in Ontario, their impact on the fires is uncertain.
