NWS: Air pollution likely to build up in the Yakima Valley over the weekend

Stagnant air to remain in the Yakima Valley over the weekend

YAKIMA VALLEY, Wash. - Weather leaders say air pollution could reach dangerous levels in the Yakima Valley over the next couple of days.

The National Weather Service (NWS) issued a Air Stagnation Advisory until at least 11 a.m., Monday, due to high pressure over the area.

The NWS said a low level inversion over the valley will begin to trap pollutants, affecting cities including Naches, Sunnyside, Toppenish and Yakima.

Weather leaders say even though the ban will be in effect until Monday morning, it may be extended depending on conditions.

Those with breathing issues are encouraged to follow their doctor's advice when dealing with air pollution. As of Friday morning, the Department of Ecology monitors show the air quality in Yakima is rated unhealthy for sensitive for groups.

The Yakima Regional Clean Air Agency has declared a stage 1 burn ban for Yakima County until further notice. The ban does not apply to those living within the Yakama Nation.

Under the ban, the use of uncertified wood stoves, fireplaces, inserts and other uncertified devices used to burn fuel are not allowed.

Burn ban violators are subject to a fine.
