Smoke from the fires ravaging the American West crossed the United States and reached the skies of the East Coast on Tuesday, about 4,000 kilometers away, according to weather services.
According to the New York Metro Weather website, the smoke, which was to remain at an altitude of 15,000 to 20,000 feet (4,500 to 6,000 meters) above New York, was originally from a slightly hazy sky.

For days, smoke had been trapped over the West Coast under heavy pressure.
But on Monday, she was taken east by the jet stream, the site explains.
From Monday evening, the national meteorological service evoked the presence of smoke from the West visible on satellite photos.

While the smoke caused spikes in pollution in cities like Vancouver, Portland, Oregon, or San Francisco, it was to have only a limited impact on the air quality of the American economic capital, said these two sites.
The smoke was expected to clear by Wednesday, according to New York Metro Weather.
