Smoke Update for Washington State

The westerly winds cleared out all that stagnant smoke across the state yesterday, as expected.  Most of us in Washington have been able to get at least a few hours of Good air at times.  We are seeing less severe air quality problems around the state, with more localized patterns coming into play.  There is also some significant rain expected for the North Cascades on Sunday which is always welcome this time of year!

Western Washington

The Vancouver Island fires continue to generate smoke that is causing Moderate to Unhealthy smoky conditions at times around the west and north coastal areas of the Olympic Peninsula.  Port Angeles looks to be getting the worst of it.  Other parts of Western Washington have also been getting intermittent smoke, which is Moderate to Unhealthy for Sensitive Groups.  Thurston, Mason, and Kitsap counties are likely experiencing a mix of light to moderate smoke from the Maple Fire and the Vancouver Island fires.  Snohomish, King, and Pierce counties may also be seeing some of that as well.  Whatcom, Skagit, and Island counties are likely seeing some of the fringes of the BC wildfire smoke plumes.  

This intermittent smoke we are experiencing should be expected through the weekend.  Southwestern counties will likely continue to see the best air quality in the region.

Central & Eastern Washington

There is a large plume of smoke (see below) from BC and Central Washington wildfires over a large portion of Central and Northeastern Washington that is mostly aloft, but the models are showing that air quality is expected to get worse Friday afternoon in Chelan, Okanogan, Ferry, Stevens, Pend Oreille, Spokane, Douglas, Grant, and Lincoln counties.  It's unclear how much of that smoke will mix down to the surface.  The forecast does have most of that clearing out by Saturday morning for Spokane, Lincoln, and Grant counties.  However, Chelan, Douglas and all the Northern counties are set to remain under an air quality alert through the weekend, with Unhealthy air expected.  Yakima county has a couple fires of its own (Miriam and Meninick Pass) which are causing Moderate to Unhealthy for Sensitive Groups air quality that is expected to continue through the weekend and may even have minor effects on downwind counties.  

There are still a considerable number of fires in the eastern slopes of the Cascades and the Colville National Forest which will send smoke to various parts of Central and Eastern Washington throughout the weekend.   The southeastern counties should continue to see the best air quality in the region.
