Western Washington is expected to remain Good through the week.
This site is an effort by county, state, and Federal agencies and Indian Tribes to coordinate and aggregate information for Washington communities affected by smoke from wildland fires. The information is posted here by the agencies themselves while volunteers built and maintain the page.
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).

August 29, 2015 - Evening update: fire, rain, wind, and smoke
[ERRATA--posted a map here from MesoWest, which mistakely showed temperatures instead of wind speeds]
This led to some blowing smoke, and increased fire activity, especially on the Carpenter Road fire (at least a couple thousand more acres likely burned). Now, we'll likely have some smoke settling into the area, especially the Chewelah Valley/Colville area, but also in some other place with nearby fire activity:

August 29, 2015 - Noon update: Wind-blown smoke from the Carpenter Road fire.
![]() |
Smoke could be heavy in locations NE of the Carpenter Road fire today. |
Air Quality Forecast - Chelan Lake & Methow Valley Fires - Saturday, August 29, 2015
Note
that our forecast format has changed. Starting today we will be showing air
quality conditions for the previous day along with forecasts for today and tomorrow.
Saturday:
With the passage of a powerful cold
front today, winds will move smoke away from communities in the vicinity of
the Wolverine, First Creek, and Chelan Complex fires. Some smoke may drift in but will be
transient and not remain. This may be a great time to air out the house.
Sunday:
Following Saturday’s storm passage Chelan,
Manson, and Brewster will see smoke settling into these areas beginning
mid-afternoon. Due to their
proximities to the fires, Manson and Brewster may see heavier concentrations
with Brewster approaching levels unhealthy for sensitive groups. This will be
short lived as the smoke is expected to generally clear overnight in each of
these areas.

8/28/2015 Have you seen some of the work of the 4 ARA's currently working in Washington?
8/28/2015 Air Quality and Smoke Report for SE Washington
Wildfire smoke forecast through Monday 31 August
Some clearing occurred Thursday evening. Here is the satellite picture taken last afternoon.
Smoke returned overnight. Most areas however are showing Moderate or USG air now. Goldendale temporary monitor reporting Good air overnight. Southwest winds will slowly pick up across the Columbia Basin and air quality will improve at most sites today. Expecting mostly Good air later today, although the Lewis- Clark valley might be harder to clear out and might stay Moderate.
Winds briefly turn easterly overnight as low pressure approaches from the coast. Some models emphasize this more than others. If this does materialize, it will drag some Idahoan smoke over far eastern Washington and also result in some smoke making a run for the western foothills of the Cascades, if not into Western Washington overnight. However any smoke on the west side will be short lived, as strong southwest winds kick up on Saturday morning, bring rain to western WA and the Cascades.
Saturday should see mostly Good air quality in these areas. However please pay attention to the Red Flag warnings and Blowing Dust advisories in eastern Washington.
Winds will remain strong enough to maintain mostly Good air on Saturday night into Sunday. It is not impossible for some Oregon wildfire smoke to make its way over parts of the Columbia Basin on Sunday, but it is unlikely to degrade air quality very much.
Expect mostly Good air on Sunday, though Moderate air cannot be ruled out. Better air in the afternoon, slightly worse overnight.
Nevertheless the Air Quality Alert remains in effect because smoke clearing will not be sustained through the entire weekend.
