Stagnant weather conditions continue to expand and persist in Central and Eastern
Washington, prompting the Washington State Department of Ecology to extend the
Stage 1 Burn Ban in Chelan, Douglas, Kittitas, and Okanogan counties until further
A persistence of strong, high-pressure weather is keeping air conditions stagnant, putting
communities at risk for unhealthy levels of air pollution. Fine particles from wood
smoke can easily get into people’s lungs causing heart and breathing problems.
Under a Stage 1 Burn Ban, all outdoor burning is prohibited including residential,
agricultural and forest burning. Use of uncertified wood stoves, fireplaces, inserts, and
other uncertified wood-burning devices is prohibited unless they are a home’s only
adequate source of heat. Certified wood stoves, pellet stoves and other certified wood-
burning devices are allowed.
