Smoke / Air Quality Summary for Friday, August 15, 2014

Smoke Synopsis:

Once again, most fire areas received between one quarter and one inch of rain yesterday.  This has further reduced fire activity and will continue to allow firefighters to be more aggressive today to strengthen containment lines, although debris flows across roads and slippery slopes are causing safety problems of their own.  High humidity will cause more smoldering, and although not a significant amount of smoke is being generated, it will remain relatively close to the ground and in the valleys.  Winds will continue to be quite light. Information on new fire starts from the recent lightning may not appear for a few days. Any new fires will affect the smoke forecast.  Smoke will accumulate, flush out and accumulate again in several areas through Saturday, especially morning around Ellensburg, the Methow Valley, and the Hwy 21 corridor near Keller. Smoke from fires outside the state may occasionally impact cities close to state borders to varying extents, especially Saturday and Sunday.

8-14-14 Air Quality Report

Smoke Synopsis:
A slow moving low pressure system over North Central Oregon will remain nearly stationary today and then slowly track into Northeast Washington on Friday, resulting in: a continuation of showers and thunderstorms over the area, reduced fire behavior, and greatly improved air quality.  Typical down-valley flows along the eastern Cascades will be moderated. Due to the continued precipitation over the area and significantly reduced fire behavior, air quality is anticipated to be good through early Saturday, with some possible areas of moderate AQ directly down drainage from the most active fires. Continued fire activity at the Devil’s Elbow Fire is expected to affect Keller and other areas down the Highway 21 corridor.
