Washington Smoke Map

*The map above is not able to display all state air quality monitors. Click here to see all monitors in Washington: WA Ecology Air Monitors

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?

We have some fires burning in Washington but it's a pretty good guess that much of the smoke impacts we're seeing in the north central part of the state are coming from Canada again. The image below is a satellite view from yesterday (today's image will be available later this afternoon) and you can see there is vastly more smoke lurking north of the border than is being produced by wildfires in our state. The second image shows all the fire activity they are still dealing with in Canada.

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.

  2. Thanks for this explanation. Definitely a bit hazy this afternoon (Aug. 1) in Olympia.
