Air Quality forecast, 8AM Friday 21 September 2012
Issued by Ranil Dhammapala, Washington State Dept. of Ecology

Western WA has cleared out well under the stronger marine push and will stay that way today. Air quality in the Columbia Basin and the Palouse/ Spokane has been deteriorating very gradually over the last few days and is mostly in the "Unhealthy for sensitive groups" category this morning. Air in these areas may improve slightly but not hugely, Saturday evening through Sunday evening.

The areas of serious concern- located at the eastern foothills of the Cascades- continue to remain problematic. Air in Wenatchee has remained in the "Hazardous" category for several days now, with each day being a little worse than the previous. Cashmere and Entiat are in a similar situation, while Leavenworth, Ellensburg, the upper and lower Yakima Valley and Chelan have been recording Very Unhealthy conditions. This scenario is not expected to change much over the next few days.

The approach and passage of a low pressure system Friday night through Saturday evening gives rise to a small threat of dry lightning in the Washington Cascades mostly south of Lake Chelan. Given the dry fuels in the area, we can only pray that there won’t be new fires for the already stretched firefighters to contend with.

Some cooler temperatures are on tap for eastern WA next week and this should help reduce fire activity, but the kind of soaking rain needed is a notable absentee from the forecast.

The National Weather Service issued an Air Quality Alert for much of eastern Washington:

9/19/12 Air quality in Wenatchee remains hazardous

Washington Department of Ecology news
FOR IMMEDIATE RELEASE – Sept. 19, 2012
12-310

                Air quality in Wenatchee remains hazardous

      SPOKANE   Smoke from wildfires continues to create hazardous air conditions in the Wenatchee area today for the eighth day in a row. Residents along the east side of the Cascades from Yakima northward through the Methow Valley to Omak continue bracing against the onslaught of smoke. 

      Ellensburg experienced some clearing Tuesday, but it was short-lived and the area filled in with smoke overnight. Ellensburg was the only part of the east Cascades region to get a slight reprieve Tuesday.

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

      Aside from the very northern counties in Eastern Washington north of Highway 2, the smoke will continue today with little daytime clearing. Conditions are not expected to improve significantly in the next several days.

      In far Eastern Washington, most areas have “good” to “moderate” air quality today, but Moses Lake has seen some excursions into the “unhealthy for sensitive populations” zone, according to Air Quality Advisory categories (https://fortress.wa.gov/ecy/publications/publications/0802022.pdf). Sensitive populations are young children, older adults and people with breathing problems such as asthma. 

      The National Weather Service continues an air stagnation advisory for the eastern foothills of the Cascades and for the Clarkston area of Whitman County (http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=otx&wwa=air%20stagnation%20advisory).

      The Wenatchee Complex Fire pushed air quality into the hazardous zone for the first time since the state began monitoring small particle pollution including smoke. The smoke hazard recorded at Wenatchee has been about three times higher than any other readings recorded by Washington state monitors since the 1980s.

      In 2006, a wildfire known as the Tripod Complex Fire burned for about two months in the Methow Valley, causing what was then the highest concentrations of small particle pollution ever measured in Washington.
