Smoke from the western US engulfs New York City skyline

New York and parts of the eastern United States and Canada are shrouded in a gray smoky haze from fires burning in the western United States and Canada. New York state's environmental protection services issued an air quality advisory, automatically triggered when fine particle matter is expected to rise above 35 micrograms per cubic meter of air. An expert from the agency said it is not uncommon for smoke from fires in the west of the country to reach the New York area, but they usually remain high enough to not affect air quality. This time, the smoke was lower than usual, the expert said.
