Philadelphia now has worst air quality compared to all major cities
UPDATE: After waking up to "hazardous" or "very unhealthy" air quality, smoke will lessen Thursday. Conditions will improve for sure by Sunday.
PHILADELPHIA (CBS) -- Philadelphia now has the worst air quality of any major city in the world as smoke from wildfires in Canada is moving through the region.
The most hazardous smoke from Canada is currently moving through the area from Wednesday night into early Thursday morning.
According to AirNow.com's Air Quality Index, Philadelphia is currently at 447. The air particles are considered "hazardous" at 300. Everyone is likely to be affected due to the hazardous quality of the air.
The Lehigh Valley ranks as the second worst air quality with 419, while Susquehanna Valley ranks third. Across the river in New Jersey, Monmouth, parts of Burlington and Ocean Counties are also experiencing harmful conditions.
The forecast models are showing some improvement for Thursday, but air quality alerts are expected through the evening at least at this point.
