Smoke from Canadian fires drifts south, impacting Midwest and Northeast regions
Parts of the Midwest and Northeast United States experienced hazy skies and declining air quality over the weekend due to smoke traveling from Canada, where thousands of wildfires are currently active.
One of Canada’s worst fire seasons in history
Canada is facing its second worst wildfire season on record, with nearly 4,000 fires reported so far this year. The resulting smoke has crossed into the U.S., affecting multiple states and prompting public health advisories.
Wisconsin, Michigan, and Minnesota reported concerning air quality levels over the weekend. Illinois and Indiana are also under air quality alerts, while states such as New York, Vermont, New Hampshire, and Maine have urged residents to reduce outdoor activities due to the smoky conditions.
Health advisories extended amid high pollution levels
On Friday, Minnesota extended its statewide air quality alert through Monday, August 4, marking its longest such advisory since 2008. While some regions showed slight improvement by Sunday, air quality was still forecasted to reach the “red” category, classified as unhealthy for all individuals.
Officials cautioned that even healthy individuals could experience symptoms like eye irritation, coughing, or shortness of breath. Those with preexisting heart or lung conditions may face heightened risks, including asthma attacks, heart attacks, or strokes.
Elsewhere, Wisconsin and Michigan also extended their alerts through Monday in response to continuing pollution levels.
Fire activity and smoke transport expected to persist
Over 700 wildfires were active across Canada on Sunday, with more than 500 classified as out of control. Most were concentrated in the province of Manitoba, directly north of Minnesota. Thousands of residents have been evacuated due to the fire threat.
Current wind patterns suggest that smoke could continue to move southeast into the U.S. throughout the week, contributing to prolonged air quality concerns in affected areas.
