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).

Expect smoke in western WA Monday- Tuesday; continuous smoke thoughout eastern WA

Note: Many Red flag warnings in effect. PLEASE do your part to prevent fires

Western WA smoke forecast
Some smoke from Oregon showed up from the southwest overnight but for the most part, has remained around 10K ft aloft. Here's a timelapse from Skunk Bay this morning:

Air quality has been mostly Good for the last 24 hours and will likely remain that way for much of Sunday.

There is consensus among models that east winds will start up early Monday morning and persist through Tuesday evening at least. Here are how all the weather models depict relative humidity at SeaTac airport.

The thick black line is the average of them all ("ensemble mean" in geek-speak). Times are in GMT, so subtract 7 hours for local time. When dry air from eastern WA invades, the humidity stays low.

These east winds will transport smoke from the Jolly Mountain fire into the Seattle area, and the Norse Peak fire to southwest WA. There is a chance that smoke from the Diamond Creek and Uno Peak fires could foul up northwest WA. By Tuesday some of this smoke could find its way to the Washington coast. Air quality is likely to vary from Moderate to Unhealthy at different times and places. In general, partial clearing during the day and poor air at night.

Wednesday could bring some short-lived relief as winds shift to south-southwest. Oregon smoke is lurking to our south and could surge into western WA. Hard to win when there is only one "clean" wind direction to work with, i.e. northwest. Please stay tuned.

Eastern WA smoke forecast
Wish I had better news for these folks who have been assailed by wave after wave of smoke. Next several days will to be no different. While east winds starting early Monday reduce smoke transport from Cascades → Columbia Basin, smoke from fires in Idaho and Montana are likely to fill the void and blast far eastern WA.

  • Kittitas and Yakima valleys could see a repeat of yesterday, with Unhealthy air gradually improving later in the day Sunday & Monday
  • Far eastern WA and the Methow valley are unlikely to deteriorate more than Unhealthy for Sensitive Groups today and tomorrow.
We are looking into ways to provide communities with localized and timely information. Please stay tuned as resources are stretched very thin.


  1. We're in North Kent and not only getting smoke (Moon is blood red), but my car is covered with particles of Ash?

  2. We are from Yakima where we have experienced very heavy smoke for days. Woke up today to ash on everything. Which fire is that from?

    1. Its hard to know exactly where ash is coming from for a given area. There are many fires in the cascades that could be the source.

  3. Hows the air quality in hoodsport? My grand mother lives there?

    1. According to the https://airnow.gov website. The air quality is currently in the Unhealthy for Sensitive Groups category. If the monitor map at the top of this page does not open, go to the website provided in this reply for more air quality readings.

  4. Live in Kittitas Cty. it is Wednesday, September 6 I'd like to find a site to look for the forecast for the smoke. Will the winds be moving the smoke at all in the next few days? that sort of thing. I'm not having a lot of luck just looking around .. this blog, air now, Noaa.. thank you in advance
