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).

Wildfire smoke forecast through Wednesday 16 September
While large scale smoke build-ups are not expected over the first half of this week, the onset of significant rain and wind has been delayed to Wednesday evening. Some light east winds are expected on Tuesday night and this is expected to drive some smoke toward the eastern foothills of the Cascades. Some models even hint at small amounts of smoke in western WA.
Between now and Wednesday afternoon, Ellensburg, Yakima and Goldendale could see Moderate to USG air at times while remaining areas are likely to vary between Good and Moderate. Winds are likely to pick up after that but valley communities will probably be slower to scour out. Good air is expected statewide by Thursday.
