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).

    1. Sorry for the delay in responding to all the comments.
      Expect clearing this weekend, starting on Saturday and gradually improving through Monday.

  2. Having the updating air quality dots for different areas is very helpful! Thank you! Sometimes dots close together vary a lot though eg 2 dots around Olympia last night (Sun eve) and this morning the northern coast and several around Seattle. Why the differences and how often do the dots recalculate/get updated?

    1. We blogged about reasons for large differences within short distances here: http://wasmoke.blogspot.com/2017/08/monday-and-tuesday-will-be-like-sunday.html.
      Colors are recalculated every hour and data from the past several hours are considered.

  5. The map on this site is pulled directly from the federal Environmental Protection Agency (EPA). EPA has developed a nationally applicable scale to warn the public about health effects from air pollution - the Air Quality Index or AQI. Washington Department of Ecology developed an air quality advisory that is more protective of public health and is called WAQA (rather than AQI). Basically, it changes color at lower levels of air pollution. There’s a little note right below the map displayed on the blog that advises people to go with the more precautionary level if the two maps differ. Thanks for your question.

  6. Where is the air quality for Pend Oreille County? There is over 3500 acres burning right now in Metaline Falls, WA... the Noisy Creek fire! The residents have been waking up to a haze of smoke for over a month now & it's only getting worse... can't tell me the air quality is fine.

    1. As we speak, Ecology is installing a temporary air monitor in the city of Newport, Pend Oreille County, for the Noisy Creek fire. Once it starts reporting, it will appear on the blog map above. It should be reporting by tomorrow (Friday, Aug 11). We're also working on getting a monitor installed in Metaline Falls. We'll follow up with that information shortly.

  7. How are conditions for north cascades national park this weekend looking?

    ReplyDelete
    Replies
    1. Conditions look good! It will be partly cloudy and temperatures will be warm. The afternoons will see a bump-up of winds to ~10 mph, but calmer winds in the evening. The NCNP should continue to see clean air throughout the weekend, as winds will be from the west. Smoke from the Diamond Creek fire should travel east and not be a problem for the NCNP. Smoke from the BC fires will likely make its way to the northeast corner of WA, completely missing NCNP.

  8. My Family and I are hoping to hike to Melakwa lake Aug. 25-28th. Will this be safe? I am finding inconsistences in various online smoke/fire maps. Thanks.

    ReplyDelete
    Replies
    1. Hi,

      The Jolly Mountain fire lies just to the northeast of Melakwa lake. Winds through Saturday should keep you upwind of most of the smoke. However light winds on Sunday and Monday do leave room for some drainage of smoke to the area. I'd expect air to be mostly Good through Saturday and Moderate or Unhealthy for Sensitive Groups afterward. Depending on your family's respiratory health and medical needs, you might want to look through the resources on this blog (http://wasmoke.blogspot.com/p/federal.html) or consult your doctor.

  9. Is there a chance the Chelan monitor is not working again ---- Twisp, Winthrop, Wenatchee, and Leavenworth have bad air, but Chelan is staying at GOOD, and has all day. Malaga and Quincy are showing GOOD also ---

    ReplyDelete
    Replies
    1. Eileen, Malaga & Quincy are SO2 and NOx monitors- not very responsive to wildfire smoke. Chelan's readings are rising- pretty close to Moderate now. Here's a comparison of the timeseries of nearby monitors: https://tools.airfire.org/monitoring/v3/#/?monitors=530070007&monitors=530470009&monitors=530470010&monitors=530070011&monitors=530251002&monitors=530370002&monitors=530470004&date=LATEST&productType=plotTable&userProfile=simple

    2. I'm curious as to why your monitoring sulfur dioxide (SO2) and (NOx) oxides of nitrogen at these locations? Is there fossil fuels being burned for power generation or industrial processes in this region? Thanks.

      Delete
    3. Tom- the SO2 monitor is downwind of the Alcoa smelter in Malaga. NOx monitoring in Quincy is a special project: to assess community exposure to backup diesel generator emissions (at the data centers and food storage/ processing facilities), and railroad + traffic emissions.

  10. Hi there,
    I was planning on hiking greenwater and echo lakes this weekend 9/1-9/2 would you predict the air quality to be poor due to the proximity of the norse peak fire? or will the wind be pushing it the other direction?
    Thank you for all your hard work!

    ReplyDelete
    Replies
    1. High pressure will build over the weekend, leading to light, terrain-driven winds. Expect smoke to pool around and for dispersion to be poor. Even if the winds are stronger, they will likely be easterly at times, transporting some smoke from the Norse Creek fire to Greenwater/ Echo Lakes. USG or even Unhealthy air cannot be ruled out. Please see our page on "Smoke and Health" (http://wasmoke.blogspot.com/p/federal.html).

  11. Any smoke updates for the Ross Lake area for Sept 1-8? We are traveling all the way from Georgia and have no idea if we are in for a problem. Any update would be much appreciated! Thank you! Edward

    1. Ross Lake is about 30 miles west of the Diamond Creek fire. Though, winds should continue to come from the west through this weekend, and terrain is in your favor, so you shouldn't see smoke at Ross Lake. However, winds are expected from the south next week, so you will probably see some smoke coming from Oregon or the Norse Peak fire (east of Mt. Rainier) during the 2nd half of your trip.

  12. Headed to Chopoka Lake Sept 4th, what do you predict the air quality will be? Smokey or hazy?
    Thanks!!

    ReplyDelete
    Replies
    1. The Diamond Creek Fire is just to the west of this area. With light winds there will be lots of smoke draining toward the lake, and no substantial clearing. Air quality is not expected to be much better than "Unhealthy for Sensitive Groups" tomorrow.

      Delete
  13. Is it expected to clear at all during the week? Was planning on being at Chopoka Monday-Sat.

    ReplyDelete
  14. While there could be periods of "OK" air during the week, there is nothing in the forecast suggesting smoke will completely clear out and stay away. That fire is expected to keep going the rest of the season and will take a good dousing to put it out.

    ReplyDelete
  15. The air monitor page has errors on it. It would be nice to flip open this website and see immediately what air quality is. There is no site that does that that I can find. You dig through and get sketchy outdated information buried in the website. Many of us in Ellensburg get Tri Cities or Yakima news which is rarely relevant to us, so we are without data. We rely on online data.

    1. The map of air quality monitors above is definitely straining under load, and some sites have not updated for several hours in spite of monitors operating normally. However Ellensburg data are current at the time of writing. Between the map above, Ecology's air monitoring page (https://fortress.wa.gov/ecy/enviwa/), PSCAA's Airgraphing tool (http://airgraphing.pscleanair.org/) and EPA's AirNow site (http://www.airnow.gov) you should have few problems getting up to date info on local air quality. All share common data sources, but there are some differences for various reasons. The map above is the most comprehensive.

    1. The WA Ecology Air Quality monitoring site is being overwhelmed with hits such that it may not come up. Try https://www.airnow.gov.

    Replies
    1. The smoke level in most of Eastern and Central WA is in the Unhealthy or worse category. Smoke from many wildfire sources may be contributing. For information on new fires please see the InciWeb link under the “Where’s the Fire” tab on this website. We will try to post a smoke forecast every day or every other day. For more health guidance please see the “Smoke and Health” tab on this website for WA Dept. of Heath recommendations, as well as contacting your local health department for those specifics.

  21. Thanks for your thorough up-to-date reporting! You've given us a much better grasp of how/what/why/when. One suggestion: The color codes legend is buried under a tab on the "Air Quality Now" page. Would it be possible to put a "color code" link in the header??

  23. The information on this blog is a tremendous public service. The local and national news sources aren't able to keep up. It is too dynamic and real-time. We're all being impacted and seeking information as residents. Thanks to those asking questions and the quick responses from Ranil-WA Ecology and CBennett-ECY.

  25. Good Day. Thank you for having this valuable information readily available. There is one site in my area that consistently (no daily deviation) reads a WACA of "Good" although this is highly unlikely due to the surrounding area readings. I checked the particulate count and the number was near zero:

    Site Name Malaga-Malaga Hwy
    Location 8100 Malaga Alcoa Hwy
    Region Chelan
    Owner ALCOA
    Purpose Air Quality
    Longitude -120.104120
    Latitude 47.343563

    1. Don, this is a sulfur dioxide (SO2) monitor downwind of the Alcoa smelter in Malaga. There are no PM2.5 measurements made on site, and SO2 is not a major component of wildfire smoke. We have debated a lot about its inclusion on the web page as it can be misleading to the public for the very reasons you mention. No easy answers here

  27. Good Morning Mr. Dhammapala- I've read many of the Q and A above, and am very impressed w/ your analysis and responses. So here's my dumb question: 5 of us located in central and southern USA are coming to Lake Chelan this next week, Sept 11th thru 15th, and are concerned about the smoke problem. We are w/o any real knowledge of danger levels, so I ask:
    1. Will it be dangerous to drive from Seattle to Chelan on HY 2?
    2. Are fires being contained and/or eliminated w/ daily improvment forecast OR are fires
    spreading w/ new start-ups happening in the Chelan area?
    3. With the current "unhealthy" warning, is it just atmospheric haze that warrants that warning
    level?
    4. Would it be the smart decision to cancel the trip?

    Thank you so much for your reply.

    1. Hi Tim,
      (1): No road closures on Hwy2 I'm aware of. Keep an eye on http://wsdot.wa.gov
      (2): Mixed bag. Some progress containment, extinguishing of small fires but no elimination of larger ones yet. Yes some are spreading and the possibility of new flare ups is always real. See https://maps.nwcg.gov/sa/#/%3F/47.2309/-119.1785/7
      (3): All warning categories discussed on this page refer to the health effects of poor air quality.
      (4) Thats a personal decision. Air quality on Saturday should be somewhat decent, but Sunday- Tuesday arent looking pretty. Some improvement is likely after Wednesday. In general, intermittent smoke impacts due to the proximity of the Uno Peak fire at Lake Chelan, but not as bad as what they just had. I'd say no worse than "Unhealthy" air. Please see the "Smoke and health" page on this blog and keep an eye on the air quality monitor there: https://fortress.wa.gov/ecy/enviwa/StationInfo.aspx?ST_ID=10
