AIR QUALITY – Large sections of the Great Lakes, Ohio Valley, Midwest, and Northeast are under air quality alerts due to wildfires burning in eastern Canada. This has been the worst wildfire season on record in Canada, even though it’s only June and wildfire season persists into the fall. According to the Canadian Interagency Forest Fire Centre, over 19.7 million acres (7.8M hectares) have burned in Canada and as of June 27th nearly 500 wildfires continue to burn (above).

As of Wednesday night, air quality alerts have expanded from the Great Lakes, Midwest, through the Northeast and Carolinas.
