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: August 3-5
The good news is that winds are picking up across the state and eastern Washington will continue to see improving air quality through the rest of the day. Some hard-hit areas in the Columbia basin are now reporting good air quality. Winds are likely to remain moderate to strong in eastern Washington through Wednesday, so smoke is unlikely to build up. The caveats are that strong winds could boost fire activity (The National Weather Service issued a Red Flag Warning through Tuesday night), and limit how high smoke plumes rise.
Air quality is expected to range between Good and Moderate in areas away from the fires. In general, better air during the daytime, slightly worse at night. Closer to the fires, air is likely to vary from Moderate to Unhealthy at times.
