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).

Additional Air Quality Concern
winds over the next 24 to 36 hours will produce conditions for increased
The current forecast calls for increased winds with gusts strong enough to
raise dust across the western portions of the Columbia Basin and in the
agricultural areas north of the Blue Mountains in southeast Washington.
This dust, combined with the continuing presence of wildfire smoke, will
produce poor air quality in the Unhealthy to Hazardous categories.
