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).

Smoke forecast through Friday 14 August
Chelan, Leavenworth, Wenatchee and the Methow Valley are currently seeing air quality ranging from Moderate to Unhealthy. Smoke is also making its way into the Kittitas valley and Columbia Basin, with several areas on the cusp of Moderate air quality. This picture is not expected to change significantly through Thursday night. In general, some relief during the afternoon followed by poor air quality at night. We should see a little more relief from smoke on Friday.
Some thunderstorms have already rolled through eastern Washington today, making for complex local wind patterns and firefighting conditions. Plenty of lightning and some downpours. Expecting the same on Thursday afternoon and evening. On Friday winds are likely to ramp up and help blow away some of the accumulated smoke but they are also likely to fan the flames of new and existing fires. A red flag warning remains in place until 8PM Thursday.
