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 - Chelan Lake & Methow Valley Fires - Thursday, August 27, 2015

Air Quality Forecast - Chelan Lake & Methow Valley Fires       Thursday, August 27, 2015

Note: Air monitors in Brewster and Manson are up and running. Look for their data at wasmoke.blogspot.com
Thursday: Yesterday, burnout operations on the Cougar Creek Fire, southwest of here, added additional smoke to areas near the Chelan Lake and Methow Valley Fires. Today, the smoke will gradually lift with the inversion with slight improvement in air quality.  However, strong winds in the morning will result in greater fire activity and generate more smoke which will settle in valley communities later in the afternoon and through the evening. 
Friday:  Light winds will be insufficient to cleanse smoke from affected communities. Smoke is likely to affect these areas more towards the evening as it settles into the valleys. Any burnout on the Cougar Fire could bring additional smoke into our area.
Saturday: A frontal passage is expected to bring strong winds and some rain.  This may provide communities downwind of the fires some relief from smoke conditions seen earlier in the week.
