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 Wednesday, August 26, 2015

Air Quality Summary Report   -  Chelan and Methow Valley Fires     Wednesday, August 26, 2015

Prepared by: Carolyn Kelly, Air Resource Advisor Trainee (ckelly8384@gmail.com
Andrea Holland, Air Resource Advisor (andreahollandsears@gmail.com)
Note: Air monitors in Brewster and Manson are currently in the process of setting up and should begin running by the weeks end.
Wednesday: Communities near the fires (Chelan, Manson, Twisp, and Winthrop) will continue to experience periods of unhealthy air quality levels especially early morning and late afternoon as smoke settles into the valleys.  The amount of smoke in Leavenworth and Wenatchee is expected to vary throughout the day reaching moderate air quality levels, with some clearing late tonight.  Smoke may be heavier in Leavenworth.
Thursday:  Chelan and Manson may see periods of increased smoke throughout the day but overall air quality will remain in the unhealthy range. Winthrop and Twisp may see varying levels of smoke with overall air quality at the unhealthy level. For Leavenworth and Wenatchee, some smoke may continue to linger but should clear out starting in the morning.
Friday: Chelan and Manson will still see smoke with potential for a decrease as the day goes on. Winthrop and Twisp may see some clearer skies earlier in the day but smoke is expected to return into the afternoon. Some smoke may return in the morning for Leavenworth and Wenatchee.
Weekend Outlook: A frontal passage is expected to pass through the area Friday night and through Saturday bringing breezy winds and some rain.  This will provide communities downwind of the fires some relief from smoke and good air quality.
