Canadian wildfire smoke live updates: Worst air quality yet may be headed to New York City

(NEW YORK) — Hazy and dangerous fumes from ongoing Canadian wildfires have engulfed the skies over most of the Northeast coast, prompting serious air quality alerts.

Thirteen states have issued those alerts as the thick fumes block the sky and send people indoors.

Canadian officials said firefighters are scrambling to put out the blazes in Quebec, where more than 160 forest fires are currently active.

FAA slows NYC air traffic due to low visibility

Due to low visibility, the Federal Aviation Administration has slowed flight traffic in and out of New Jersey’s Newark Liberty International Airport and New York City’s LaGuardia Airport.

A ground stop is in effect at LaGuardia, meaning some flights are being held at their origin airport to ease congestion.

The average delay at Newark is about 84 minutes.

Worst air quality yet may be headed to NYC

The worst air in the U.S. Wednesday morning is in upstate New York from Syracuse to Binghamton, where the air quality has reached the worst level — “hazardous.”

That air will move toward New York City and Philadelphia on Wednesday afternoon and evening.

Tuesday brought the worst air quality to New York City since the 1960s, officials said, with New York City Mayor Eric Adams calling it an “unprecedented event.”

The mayor urged New Yorkers to avoid going outside if they can.

Adams warned Wednesday, “Air quality conditions are anticipated to temporarily improve later tonight through tomorrow morning, but they are expected to deteriorate further tomorrow afternoon and evening.”

NYC mayor says air quality expected to ‘deteriorate further’ Wednesday

The air quality in New York City worsened Tuesday evening and is expected to “deteriorate further” Wednesday afternoon and evening, New York City Mayor Eric Adams said in a statement.

“At this point, the New York State Department of Environmental Conservation has issued an Air Quality Health Advisory for all five boroughs. While conditions are anticipated to temporarily improve later tonight through tomorrow morning, they are expected to deteriorate further tomorrow afternoon and evening,” Adams said.

“Currently, we are taking precautions out of an abundance of caution to protect New Yorkers’ health until we are able to get a better sense of future air quality reports,” he said.

Adams said students should still go to school on Wednesday, but New York City public schools won’t have outdoor activities.

“These recommendations may change based on updated air quality conditions that come in, but, in the meantime, we recommend all New Yorkers to take the precautions they see fit to protect their health,” he added.

New York City currently has the worst air quality in the world, data shows

New York City currently has the worst air quality than any other city on Earth, as smoke stemming from wildfires in Canada makes its way across the Northeast, according to the latest data from Swiss technology company IQAir.

The air quality index in NYC is at 196 as of Tuesday evening, followed by Doha, Qatar, and Delhi, India.

The next U.S. city on the list is Detroit, which currently places eighth, according to IQAir. Toronto, Canada, sat in ninth place as of Tuesday night.

Who is at most risk from unhealthy air

The U.S. Environmental Protection Agency has specific guidance for vulnerable groups if the air quality in their area is deemed “unhealthy.”

While the agency warns that all people will experience adverse side effects from exposure to the unhealthy air, it said those with heart or lung disease, pregnant people, children and the elderly are most sensitive.

Those groups should consider moving all of their activities indoors until the air quality alert is lifted, the EPA said.

Northeast covered in haze as forecasters warn of more smoke to come

Millions of people in New York City and other locations in the Northeast scrambled to keep themselves free of the smoky air throughout the day and evening Tuesday.

The city’s skyline was barely visible for most parts of the day, and the smell of the smoke was strong as commuters hit the evening rush.

Large cities with the lowest air quality include New York City; Albany, New York and Cincinnati, a map by Airnow, a website that publishes air quality data, shows.

Another large and dense plume of smoke will be moving down across parts of the Northeast on Wednesday, according to forecasters.

That batch of very dense smoke will push down across the Northeast throughout the day on Wednesday, giving some relief to New England and the Midwest.
