Canadian Wildfire Smoke Engulfs US Cities, Air Quality Plummets
Smoke from hundreds of Canadian wildfires pushed into the U.S. Midwest and Northeast on July 16 and 17, producing unhealthy to hazardous air across population centers. Reuters reported 858 Canadian fires, including 111 uncontrolled, on July 16, while Canadian officials separately reported roughly 2.38 million hectares burned. Detroit recorded an IQAir pollution index of 600, while Chicago reached more than 600 on local monitors. Air-quality alerts covered more than a dozen states and Washington, D.C., with more than 100 million Americans affected, according to ABC News. National Weather Service alerts cited fine particulate pollution from Canadian smoke, including hazardous conditions in Michigan. NASA later documented smoke transport from Ontario into the United States and reported Baltimore-Washington daily PM2.5 near 200 micrograms per cubic meter on July 17. Conditions began improving as storms and changing winds displaced smoke. The supplied claim about 6.4 million U.S. acres belongs to later August reporting.
