Air quality in Ellensburg has reached hazardous levels as a result of smoke from north and central Washington fires.

Wenatchee air quality has been hazardous since Sept. 12, according to data gathered by the Washington Department of Ecology.

All residents in both Wenatchee and Ellensburg should stay indoors and limit their physical activities. Doors and windows should remain closed.

Weak winds and stagnant conditions will continue in the eastern foothills of the Cascades, causing impaired air quality over the next several days. Exceptions are northern Okanogan County and Klickitat County.

Elsewhere in Eastern Washington, air quality remained mostly in the "good" category, though a few areas recorded "moderate" air quality.
