Deception Complex Daily Smoke Outlook Wednesday, 9.17.2014

Tuesday, control and mop up is the primary fire operations for the remainder of the fire. Clouds and cooler temperatures helped keep the Fire contained overnight, with smoke filling low laying areas during the nighttime hours.  Smoke started to lift early, but rolled up slope when the winds switched. After sunset, down slope winds pushed smoke down Deception Creek towards Highway 58.  The Westfir recorded ” Unhealthy for Sensitive Groups” levels of PM over night and early morning, while Oakridge recorded  for only a short period “Moderate”. Early afternoon smoke rolled into the Middle Fork Ranger Station for a short period, air quality was in the “Moderate” AQI level.

Today’s smoke will transport to the southeast  in the morning; the winds will transition to the southwest in afternoon.  Forecast for cooler temperatures and higher humidity, and a chance of wetting rain later in the week, may reduce interior fire interior and smoke production.  We forecast the morning air quality to reach “Moderate” in Westfir as smoke moves down the Deception Creek drainage, and “Good” for Oakridge. Air quality in the early afternoon may reach the “Good”  for a short period clearing to” Moderate” by early evening for Westfir and Oakridge.
