Smoke from wildfires burning in Canada has caused air quality alerts for parts of New York state, including New York City.

Officials warned young children and those with respiratory illnesses to take precautions. For weeks, smoke from Canadian wildfires has been drifting across the border.

Hazy skies descend over the New York City area again on Tuesday, re-upping some air quality alerts related to Canadian wildfire smoke. As of 10 a.m., the air quality index was 121, which is considered unhealthy for sensitive groups.
