Wildfire smoke originating from northern Minnesota and western Ontario in Canada is expected to travel across the Midwest, Northeast, and Mid-Atlantic regions. These conditions are projected to persist from Wednesday through Friday.

This movement of smoke has the potential to affect air quality for approximately 100 million individuals in the United States. As the smoke sinks into the lower atmosphere, it could create an environment of unhealthy air quality across these regions.

Experts encourage residents in affected areas to stay informed and take necessary precautions, especially for those with respiratory conditions or other health concerns. Monitoring local air quality reports and limiting outdoor activities when necessary can help mitigate health risks.
