People in New York are being warned to limit outdoor activity as smoke from Canadian wildfires drifts across many areas of the northeastern US.
Air quality in the state is now “unhealthy”, according to the Environment Protection Agency, and a murky haze has descended over landmarks such as the Statue of Liberty and Times Square.
Unusually early and intense wildfires in Canada’s Quebec province are to blame – more than 150 forest fires were burning on Tuesday – and over 100,000 people have been forced to evacuate.
Lightning is said to have started many of the fires.
US authorities said residents with heart or lung disease, older people and children should keep outdoor activities short, and that others should reduce the amount they’re active or exercising.
New York state, New Jersey, Pennsylvania and the Washington DC area are among the states with an “unhealthy” fine particulate matter reading (PM 2.5).
Toronto, Canada’s biggest city, also warned residents about the air quality and tourists at the CN Tower were met with a murky orange vista rather than clear early-summer skies.
