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.
