Air Quality Report and Outlook for 8/30/14

The deception fire grew 149 acres yesterday as a result of interior burning and burn out operations to strengthen perimeter control lines.  Smoke from the majority of this increase vented to the southeast in the late afternoon and evening with valleys winds blowing out of the west. Overnight, the more stable conditions trapped emissions at the elevation of the fire. These emissions will drop into the valley late this morning peaking before noon and then clearing as a result of increased west winds this afternoon.  We forecast the air quality in Oakridge and Westfir to reach Unhealthy for Sensitive Groups near noon for a short period before west valley winds will clear the area of the majority of pollutants. We anticipate the afternoon conditions in Westfir and Oakridge to improve to the Moderate range. On Sunday, another frontal system will result in north winds that should push the majority of smoke to the South.
