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.
