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).

Wildfire smoke forecast through Labor Day weekend

This week's dramatic improvement in eastern Washington's air quality will be partly sustained through the Labor Day weekend. "Partly" because it wont be as great as what we saw Monday through Thursday, but it wont be anywhere as bad as it was a week ago. Here's why:

Notice the huge improvement that occurred on Sunday 30 August, but also observe how some areas have started creeping up in the last day or so. These monitors are all located very close to the fires, and in spite of lower fire activity and an active weather pattern, the communities of Orient, Nespelem, Republic, Kettle Falls and Colville aren't seeing Good air at present. Air quality in these communities is not expected to be very different between now and Monday.

We might see some smoke from ID fires along the ID-WA border today but it shouldn’t linger beyond Saturday morning. However the Lewis- Clark valley might not clear out easily on Saturday so Moderate to USG conditions are possible there. Yakima, Klickitat and Benton Counties are likely to see Good air.

Sunday & Monday are likely to see mostly Good air except very close to the fires, though some Moderate to USG areas at night - particular on Monday night- are likely.

A ridge of high pressure is expected to build from Tuesday- Thursday next week, bringing sunshine, warmer temperatures and light winds. Unfortunately this does not bode well for air quality.
