Smoke from large Canadian wildfires spreads into the United States and is prompting air quality alerts across parts of the country. Multiple outlets report that skies over the U.S. darken as smoke intrudes, with a change in wind patterns playing a key role in carrying the haze southward and eastward. Meteorologists say the smoke is expected to affect broad regions, including the Midwest, the Great Lakes area, and the Northeast, where conditions can worsen as concentrations increase.
Reports note that air quality alerts are issued to warn residents of unhealthy conditions, including reduced visibility. While the exact number of affected locations varies by source, CBS News reports alerts in at least 16 states, particularly across the Midwest and Northeast. The overall impacts described by outlets are consistent: drifting smoke leads to degraded air quality and visibility as it moves across these regions. The situation is dynamic, with forecasts indicating continued movement of the smoke driven by changing atmospheric conditions.
