SPOKANE-- Smoke from regional wildfires continued to affect air quality in the Inland Northwest Monday.

Calm winds combined with above average temperatures have created stagnant conditions across our area trapping smoke across the Inland Northwest.

Spokane Clean Air declared a Stage 1 Impaired Air Quality Thursday. Stage 1 prohibits all outdoor burning and the use of fireplaces, non-EPA certified wood stoves and fireplace inserts. The ban includes all fire extinguisher training and fire fighting instruction fires.

Residents in Eastern Washington experienced air quality “unhealthy for sensitive groups” such as the elderly, very young children and people with breathing difficulties, heart disease or lung disease according to the Washington Department of Ecology.
