BELLEVUE, WA — More than a dozen wildfires burning across British Columbia have produced enough smoke to cover much of Western Washington, delaying flights into Sea-Tac and creating a white haze hanging in the sky. A NASA satellite photo taken Wednesday shows just how far-reaching the smoke is.

Shifting wind patterns are sucking the smoke into our region, and meteorologists predict it will be here to stay for a few days. Some areas in Western Washington, in central Seattle in particular, have air quality rated as "unhealthy for sensitive groups."

Air quality is worse in Eastern Washington, with "unhealthy" ratings from Yakima to the Chelan area. You can check air quality on the state Department of Ecology website.
