Toxic Wildfire Smoke Engulfs Major US Cities, Bringing Hazardous Air Quality and Health Risks to Millions of Americans
A massive wave of wildfires is sweeping across Canada, with nearly 900 fires burning, over 100 of which are out of control. The smoke from these fires has spread to more than a dozen states in the Midwest and Northeast, prompting Philadelphia to declare a "Code Purple Air Quality Emergency Day" on Friday.
Philadelphia officials warned that everyone may experience negative health effects from the particulate matter in the air, with members of sensitive groups potentially facing more serious health issues. Almost 200 of the fires are located in Ontario, where passing showers and thunderstorms are expected on Friday, but the rain is unlikely to extinguish the wildfires.
Heavy rain is forecasted to move over the Minnesota-Canada border, which may help alleviate some of the fires, but also brings the risk of strong winds and lightning that can spark new fires. The smoke has already reached dangerous levels from Duluth, Minnesota, to Richmond, Virginia, impacting several states including Wisconsin, Michigan, Ohio, New York, Pennsylvania, New Jersey, Maryland, and Delaware.
The worst air quality is expected on Friday afternoon from Detroit to Cleveland to Pittsburgh to Washington, D.C. However, Detroit and Chicago can expect a temporary reprieve from the smoke on Saturday morning. By Saturday evening, the smoke will have shifted to New England and returned to the Great Lakes.
On Sunday, smoke is likely to affect New York City, coinciding with the FIFA World Cup Final at MetLife Stadium in New Jersey. Authorities are closely monitoring the situation. To mitigate the health risks, experts recommend wearing N95 masks, which can filter at least 95% of airborne particles. In New York City, free KN95 masks are available at hundreds of locations.
