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 Summary Report - Chelan and Methow Valley Fires Tuesday, August 25, 2015

Air Quality Summary Report   -  Chelan and Methow Valley Fires     Tuesday, August 25, 2015

Prepared by: Carolyn Kelly, Air Resource Advisor Trainee (ckelly8384@gmail.com
Andrea Holland, Air Resource Advisor (andreahollandsears@gmail.com)

Note: The Manson monitoring site has re-established.  Yesterday an air monitor was also installed in Brewster. 
Tuesday: Decent mixing has allowed smoke to disperse overnight and into the morning in some affected communities. Expect to see generally improved air quality in the afternoon with smoky conditions gradually returning overnight. This pattern will be more apparent in Chelan and Manson.  Brewster will see improved air quality throughout the day.
Wednesday:  Chelan and Manson will again see varying levels of smoke throughout the day. Twisp and Winthrop will not likely get much relief from the smoke. Leavenworth and Wenatchee may see some smoke drift during the day which should clear out by evening.
Thursday: With uncertain meteorological information at this time, this forecast may change considerably.
