8-13-14 Air Quality Report

Smoke Synopsis:
Many fire areas received between one quarter and one inch of rain yesterday.  In general this has reduced fire activity and will allow firefighters to be more aggressive today including using burnouts to strengthen containment lines.  The increased humidity will cause more smoldering and this along with planned burnouts could maintain a notable level of smoke generation.  Cloudy skies and poor mixing this afternoon could lead to smoke staying relatively close to the ground and in the valleys.  Winds will continue to be quite light.

Yesterday's rain and wind helped disperse some smoke but information on new fire starts is still trickling in and 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. Smoke from fires outside the state may occasionally impact cities close to state borders to varying extents.
