The smoke floating over the border shared between America and Canada is now impacting air quality in states as far south as Texas, AirNow's data shows. The EPA has declared the air quality in states near the Canadian border as "unhealthy or "unhealthy for sensitive groups."

Breathing in polluted air for extended periods of time can pose a serious health risk for people, especially for vulnerable populations.

Smoke from wildfires in Canada continue to impact air quality in the northern United States, even in the New York City metro area and Hudson Valley.
