Canadian Wildfire Smoke Spreads Across US Midwest and Northeast, Triggering Health Alerts

A massive plume of smoke from more than 830 wildfires burning across Canada and northern Minnesota has descended upon the United States, degrading air quality from the Great Lakes to New England. The fires, fueled by severe drought and a persistent heat dome, have burned over 33,000 acres in Minnesota alone, triggering a state of emergency in St. Louis County and mandatory evacuations. Wind shifts have directed thick smoke southward, causing air quality to reach hazardous levels in parts of the Upper Midwest and unhealthy levels for sensitive groups in the Northeast, including New York City and Boston. Meteorologists warn that the combination of extreme heat and heavy particulate pollution poses significant health risks, particularly for individuals with respiratory conditions.
