Deception Fire

Air Quality Report & Outlook for Sunday, 9/21/2014

Despite the very warm temperatures Saturday, firefighters continued to make good progress on mop up of the fire which continues to smolder in the punky logs and organic material on the forest floor.  Saturday throughout most of the day, the air quality in Oakridge and Westfir was “GOOD”.  Saturday evening smoke moved through the Westfir/ Deception Creek drainage causing “Unhealthy” conditions for a period of about 4 hours.  

For today, Sunday, there is some uncertainty as to how quickly the inversion will lift. Temperatures will be warm, but not as warm as Saturday. Winds will be light and out of the west to northwest, pushing any smoke in an east to southeasterly direction. Throughout the day, hazy skies are forecasted lasting 1-4 hours, off & on.  However, “Moderate” to “Good” air quality conditions should prevail.  Night time down drainage flows will bring residual smoke into the Westfir/Deception Creek area again tonight and in the early morning hours.  Expecting rain mid-week.

Smoke forecasts are dependent on predicted fire growth and weather.    If conditions change unexpectedly, impacts could occur.
