Note: Some users might notice intermittent discrepancies in colors shown on the map of air quality monitors above, and those reported on the Department of Ecology's official page. This is because Ecology believes their method of calculating the air quality category (i.e. “Good”, “Moderate”, Unhealthy” etc) is more protective of public health in Washington. If in doubt as to which better represents public health risk, use the more stringent of the two (i.e. the map showing worse air quality).

8/1/2017 What is impacting air quality in north central Washington?
In Washington, the Diamond Creek fire in the Pasayten wilderness has been sending smoke into Winthrop and Twisp for the last week or so but the air quality impacts in Omak and Okanogan are probably due to smoke draining down the Okanogan valley from Canada. A new fire - the Suiattle fire - outside of Darrington is impacting air quality locally.
