Smoke drifting from wildfires burning across northern Minnesota and western Ontario, Canada, is currently enveloping the Pittsburgh region.
As of now, the Pittsburgh region is around 100 on the Environmental Protection Agency scale, and it’s expected to climb into the 200 to 300 range for the latter portions of this afternoon and evening.
The Air Quality Index’s “unhealthy” category ranges from 151 to 200, meaning “members of the general public may experience health effects,” and the “very unhealthy” category is 201 to 300.
Here is an image showing the projected concentration of smoke across the region through Friday.
