Wildfire Smoke

NBC10 First Alert Weather meteorologist Bill Henley explains how the haze high above Philadelphia and the surrounding communities on Tuesday is being caused by the wildfires burning across the country.

Smoke from the West Coast wildfires is drifting over to the East Coast and causing hazy skies and strange sunsets. But despite the odd sight, there is no threat to our air quality back east.

Increasingly intense wildfires that have scorched forests from California to Australia are stoking worry about long-term health impacts from smoke exposure in affected cities and towns.
