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).

Way more smoke in the Methow Valley. Not much change over the weekend

The Diamond Creek fire north of Mazama appears to have been annoyed by something: it puffed up way more smoke last night than it did in the past few days.



While smoke drained into the Methow as expected, the amount of smoke was an unpleasant surprise. Air quality in Winthrop has been Unhealthy since midnight and Twisp quickly caught up when the morning inversion broke. Expect some gradual improvement during the day, but not hopeful it will get any better than Moderate today.

A repeat of last night and this morning beckons on Friday and Saturday nights into the following morning, because winds will be terrain- driven each day. Slightly stronger winds on Sunday will help disperse the smoke, leading to Good to Moderate AQ in the Methow.

  1. We are in the Okanogan Valley, east of the Diamond Creek fire. The air quality is very poor here with no signs of improvement. Perhaps you could include our part of the county in your reports. Thank you.

  2. I posted before about the Okanogan Valley. I should be more specific because it is such a large area. I should have said "north of Riverside and including the Sinlahekin Valley (Loomis)." Thank you.
