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).

Air quality forecast, Thursday 17 July 2014

Washington Department of Ecology Air Quality Forecast, July 17 2014
 
In addition to several small fires, large wildfires burning close to Leavenworth, the Methow Valley and Ephrata are causing poor air quality. These fires run the risk of spreading today and tomorrow as strong winds pass through. A Red Flag Warning has been issued by the National Weather Service. Stronger winds also restrict plume rise, so more smoke will stay closer to the ground.
 
Temperatures will drop closer to normal by Friday and there is a small chance of some rain in the mountains on Saturday. Not enough to douse the fires though.
 
Winds will blow from west to east through the weekend causing wildfire smoke to drift across much of eastern Washington over the next few days. Areas close to the fires may continue to see air quality degrade to Unhealthy levels, while air in areas further away could vary between Good, Moderate and Unhealthy for Sensitive Groups at different times between now and Monday.
 
Barring new fires, air quality in south central Washington and areas further west of the wildfires should continue to remain Good during this time. We do not expect major smoke intrusions from fires in Idaho, Oregon or British Columbia.

  1. I like your site, but am finding large discrepecy in one of a station value. I suffer from COPD and having a correct reading important, especially with all of smoke we are getting.
    Your site shows the 1100 reading at the Wenatchee, Wa station of 78 - Moderate.
    The Washington Dept of Ecology Wenatchee - Fifth St station of 114 - Hazardous for Sensitive groups, also at 1100 today.
    There is nearly always a difference between the two, usually with your readings lowest.
    Can you tell me where the problem lies?
    Thank you.

  2. Thank you for the excellent question and keen eyed observation. In brief, the colored dots on the two maps rely on slightly different calculations. The map on this blog uses a nationally applicable health warning scale and the one at the link is a Washington state-specific scale developed by local health professionals. We're working on a more complete explanation but for the time being,if the two maps are different, I'd advise going with the warning that is the most precautionary. Thanks!
