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).

10-02-12 Wildfire Smoke Forecast 0800 PDT
Air Quality forecast, 8AM Tuesday 2 October 2012
Issued by Ranil Dhammapala, Washington State Dept. of Ecology

A mostly green map of air quality monitors this morning, with the exception of Clarkston, Liberty and Maple Falls (all Unhealthy for Sensitive Groups), and Colville (Moderate). Clarkston and a few other sites in far eastern WA saw short term spikes last evening when the wind direction shifted from mostly east to W-SW as the front approached. Some of this smoke appears to have gotten trapped in the Lewis-Clark valley overnight but is likely to clear this afternoon. Liberty is seeing some smoke this morning.

Smoke impacts today are expected to be minimal except close to the WA wildfires. Strong winds are expected across much of eastern WA today. They will die down overnight but gradients turn easterly tomorrow and according to some models, persist through the weekend.
* a red flag warning for wildfire growth today through all of eastern WA
* the possibility of blowing dust in the Columbia Basin today
* a hard freeze or frost in the sheltered valleys of eastern WA tonight
* an air quality alert for most of the east slopes of the Cascades through Friday
* the possibility of wildfire smoke in western WA (mostly south of Seattle) on Wednesday and Thursday
* the possibility of ID/ MT wildfire smoke in eastern WA on Wed/ Thu
we have a lot to be concerned with.

The National Weather Service issued an Air Quality Alert for all of eastern Washington through noon today:

The Governor has extended the burn ban for eastern Washington until midnight on Sunday October 7, 2012.

  1. I'm supposed to be attending a horse show in Wenatchee this weekend (Oct 5-7). Most of our time (people and horses) will be spent outside as we'll be camping at the Appleatchee Show Grounds.

    We're trying to understand what the air quality forecast for the weekend is? We were prepared to cancel our trip based on yesterday's hazardous readings - but with today's back to good and the wind/cooler air forecasted for the next few days - should we expect air quality to stay good through Sunday?

  2. Thanks for your question. Be sure to check back for updates but as of 10/2 here's the prediction from a Department of Ecology air quality modeler:
    You can expect reasonably good air quality during the day on Friday and Saturday but conditions deteriorate each night and smoke concentrations in Wenatchee will increase to Unhealthy for Sensitive Groups or Unhealthy levels before clearing out the following day. Sunday does not look to have the same degree of daytime clearing and may not be better than Moderate.

  3. Thank you very much - that was what I needed to know.
