CAMBRIA COUNTY, Pa. (WJAC) — Smoke from Canadian wildfires has caused hazy skies throughout our region, putting millions of Pennsylvanians under air quality alerts.

The National Weather Service has even issued red flag warnings across Pennsylvania.

UPMC Altoona Pulmonologist Dr. Mehrdad Ghaffari described the sky as something out of a science fiction movie.

You don't know if it's the sun or the moon, or you're on the Earth or a different planet. It's quite weird looking outside," Dr. Ghaffari told 6 News.

The poor air quality is due to recent wildfires in Canada, with the particles drifting down to the United States.

Canadian officials say there are more than 150 active wildfires burning in Quebec.

"The fine particles in the air can cause basically some breathing issues, even for people who consider themselves healthy," said Dr. Ghaffari.

Dr. Ghaffari said that while everyone should be cautious, those with asthma, COPD, and lung problems should be extra careful.

"They have to have their medication handy. If they have more shortness of breath, they use their medication more often. They should contact their physician, or pulmonologist, or lung doctor if their symptoms significantly worsen," Dr. Ghaffari said.

Dr. Ghaffari says you can monitor the air quality in your region by looking up the air quality index on your computer or smartphone.

"As the number goes higher, the air quality gets poorer,” he said. “When you get to 100, it's unhealthy for sensitive people. When you get to above 150, it's basically unhealthy for everybody."

In light of the current air pollution caused by forest fires, it is important to note that regular masks, such as surgical masks, may not provide effective protection due to the small particle size. Instead, individuals with underlying cardiopulmonary diseases who are required to work in hazardous environments with high air pollution should consider utilizing respirators, such as N95 masks. These respirators offer better protection against fine particles," Dr. Ghaffari adds.
