Smoke from wildfires in eastern Canada is flowing into large cities in the eastern United States, causing air pollution, delaying flights to and from New York and reducing visibility around the capital Washington.

In eastern Canada, a series of wildfires have recently swept across the border into large cities in the eastern United States, causing serious air pollution.

In New York, on the 8th, the smoke caused a haze from the morning, and visibility deteriorated.

In addition to delays in flights arriving and departing, some tourists were seen wearing masks walking around the city center.

Smoke also flowed into the vicinity of the White House in Washington, D.C., and the White House announced the postponement of an event scheduled for the evening of the 8th.

U.S. meteorological authorities have issued warnings for a wide area, mainly in the eastern part of the country, noting that there are areas where the concentration of air pollutants is increasing due to smoke.

Some believe that the effects of wildfire smoke will continue depending on the direction of the wind, and health authorities are urging the elderly and people with pre-existing medical conditions to refrain from going out non-essential and to wear masks when going out.
