Haze in New York, Pennsylvania, New Jersey, DC amid fires

Smoke from Canadian wildfires has worsened air quality and lowered temperatures in parts of the United States, producing views of eerie glowing sunrises and hazy, thick skylines.

On Tuesday, 238 out-of-control wildfires across Canada helped blanket multiple Canadian provinces, much of the Great Lakes region and parts of the northeastern U.S. Due to an area of low pressure that’s hovering offshore, along with an area of high pressure over Canada, a northerly flow of air was funneling the smoke south into the U.S. from Canada, AccuWeather said. 

On Wednesday, the federal AirNow fire and smoke map listed air as “unhealthy” in areas up and down the East Coast and in parts of the Midwest, including New York, Ohio, Michigan, Vermont, Connecticut, Pennsylvania, and advised residents to “reduce activity or consider going indoors.”
