Air quality alerts have been issued for states across the Northeast.
Hazy and dangerous fumes from ongoing wildfires in Canada have engulfed the skies over much of the East Coast, prompting serious air quality alerts in over a dozen states.
Canadian officials said firefighters are scrambling to put out the blazes. So far this wildfire season, Canada has seen more than 8.7 million acres burned -- an area larger than the state of Vermont.
Waves of smoke will continue to move south Thursday from New York City to Philadelphia to Washington, D.C.

By Saturday and Sunday, the winds will begin to switch and blow smoke away from the U.S.
