Smoke from the Canadian wildfires is expected to remain in the air through at least the middle of the week, according to the National Weather Service, triggering air quality alerts for portions of the country.
Alerts were in place Tuesday morning for the northern High Plains, Midwest, Great Lakes, southern Mid-Atlantic and into the Northeast, where higher concentrations of smoke will result in unhealthy air quality for sensitive groups, according to the weather service.
As of Tuesday morning, Washington, D.C., and New York City have the worst air quality conditions among American cities, according to IQ Air’s live ranking of major world cities, which ranks them 7th and 14th, respectively.
