Wildfire smoke tracker: Where the air pollution is headed next



The northeast of the United States is battling smoke from 400 wildfires raging across Canada which have burned more than 6 million acres and led to mass evacuations.

And it’s far from over: Canadian officials warned that this could be the country’s worst wildfire season on record.

Smoke has darkened skies and made it difficult to breathe in at least half a dozen states and large parts of Canada, including major cities like New York, Toronto, Ottawa, Washington DC and Philadelphia.

Which direction is the smoke moving?

People were being warned to take extra precautions due to less visibility, a drop in air quality and the “campfire”-like smell.

The fires have been burning for weeks. Why is it smoky now?

The fires in Quebec province started this weekend and blazes in Nova Scotia, on the Atlantic Coast, began last month.

This weather pattern is expected to continue until at least the weekend.
