(NEW YORK) — Hazy and dangerous fumes from ongoing wildfires in Canada have engulfed the skies over much of the East Coast, prompting serious air quality alerts in over a dozen states.
Canadian officials said firefighters are scrambling to put out the blazes. So far this wildfire season, Canada has seen more than 8.7 million acres burned — an area larger than the state of Vermont.
Here’s how the news is developing. All times Eastern:
Jun 08, 3:36 PM EDT
The large plume of hazardous wildfire smoke that moved through New York City on Wednesday drifted into the Mid-Atlantic Thursday, bringing dangerous air conditions to Philadelphia, Baltimore, and Washington, D.C.
By Thursday night, the thickest smoke will continue to spread over the Mid-Atlantic. AQI values may reach 400 in some areas. (Levels under 100 are generally considered safe.)
By Friday morning, the hazardous haze will be covering Pittsburgh and the Chesapeake Bay.
The smoke may thin out during the day on Friday with cities like New York City seeing clearer conditions by Friday evening.
Major relief will move in by Monday when a cold front sweeps across the East, washing away much of the smoke in the air.

New York City’s ‘smoke wave’ response time for warnings criticized
As New York City was bombarded with dangerous air and smoke that turned the skyline orange, some residents and environmental experts questioned if the city’s leader acted quickly enough to warn people about the dangers of the “smoke wave.”

When to expect air quality to improve in the US amid Canadian wildfires
The wind conditions that are bringing plumes of smoke south are expected to last for several more days, experts say, as some fires in Canada continue to burn out of control.
The smoke is primarily from several wildfires burning in Quebec that is being blown south in a narrow band by an intense storm system around Nova Scotia that has not moved in several days, according to Mark Wysocki, an air pollution meteorologist who teaches at Cornell University in Ithaca, New York.

What to know about the Air Quality Index from wildfire smoke and how it affects human health
Wildfire smoke contains fine particulate matter, known as PM2.5, which are microscopic solid or liquid droplets — often 30 times smaller than the diameter of a human hair — that can be inhaled and cause serious health problems, according to the EPA.
PM2.5 is considered unhealthy for “Code Orange” and sensitive groups once the Air Quality Index surpasses 100, according to AirNow, a website that publishes air quality data. Once the AQI surpasses 150, it is considered “Code Red,” unhealthy for some members of the general public who may experience health effects, with sensitive groups experiencing more severe effects.

Why the poor air quality could cause a host of symptoms — even in healthy people
Exposure to concentrated amounts of fine particulate matter can cause both short-term effects such as irritation of the eyes, nose and throat; coughing, sneezing; and shortness of breath, and long-term effects such as worsening asthma and heart disease, according to the Environmental Protection Agency.
Fine particles are able to enter the body through the eyes and lungs. Not everyone feels the same symptoms, and the pollution can exacerbate existing health issues, such as asthma and allergies, Peter DeCarlo, associate professor of environmental health and engineering, told ABC News.

How to stay safe from wildfire smoke
The most effective way to protect yourself during wildfire emergencies is to stay indoors or limit time outdoors when there is smoke in the air, according to the Centers for Disease Control and Prevention. This is especially important for those with heart or lung conditions who are at higher risk for adverse health effects.
If you can, try to avoid exercising outdoors until the air quality improves, especially those with underlying lung disease.
“People with asthma and people who already have lung disease or underlying lung problems, it can exacerbate that, it can irritate that. And if the air quality is bad enough, it can even cause some symptoms of feeling unwell and respiratory symptoms in people who are healthy,” said Dr. Stephanie Widmer, a member of ABC News’ Medical Unit.
Pregnant people should also try to avoid spending time outdoors, especially those who are further along, Widmer said.
You should wear a mask that covers your nose and mouth, fits tightly to your face and can filter out smoke or ash particles before you breathe them in, according to the CDC. N95 or P100 masks can help protect your lungs from smoke or ash.
