States across the U.S. are feeling the impact of the Canadian wildfires as air quality takes a hit from the smoke, according to a government website that tracks air quality in the United States.

Smoke from Canadian wildfires is causing air quality concerns for millions of Americans in the Midwest and Northeast.  Air quality alerts were in effect Tuesday in several states, including Michigan and New York.

Red flag warnings remain in place for parts of Nevada, Utah, Colorado and Wyoming due to very dry conditions, low humidity and gusty winds.
