Canadian Wildfires Cause Hazy Air Quality Across US Midwest and Northeast.

Smoke from wildfires in Alberta, Canada, is causing an orange-like haze in the skies above the D.C. region, but it is not expected to substantially impact air quality. The smoke remains high enough above the surface, but if it is forced down, it could be dangerous to those with respiratory ailments. There are 91 wildfires burning in Alberta, 27 of them are out of control.
