"Canada Wildfires' Smoke Continues to Impact East Coast Air Quality"

Smoke from wildfires in Canada has caused a dangerous smoky haze in the Philadelphia region, leading to a code red air quality alert. The smoke is being funneled through the northeast due to weather conditions, but is expected to gradually improve by Thursday and cut off completely by the weekend.
