Department of Environmental Conservation officials say New York is experiencing the worst air quality since 2002 due to wildfires in Canada.

News 12 was on the waterfront at Pierson Park in Tarrytown, where the view was obscured Tuesday by a thick haze.

There are multiple wildfires raging in Canada, in Quebec and Nova Scotia and the smoke is impacting millions of Americans across the northeast and as far down as the Carolinas.

"It is a very dry year, a warm year and there are concerns that these conditions will persist," said Basil Seggos, New York’s DEC commissioner.

The DEC has issued an air quality advisory for the Hudson Valley. New Yorkers are being urged to stay indoors, especially those with respiratory issues.

Dr. Paul Pechman, a pulmonologist at Scarsdale Medical Group, told News 12 that many individuals have been “experiencing symptoms including shortness of breath” and “irritation of eyes.”
