Deception Fire Air Quality Report and Outlook for 9/18/14

Yesterday “Moderate” impacts were localized to the communities around Oakridge and Westfir between 11 a.m. to 1:00 p.m. The rest of the day the air quality index was “Good”. 
Rain is predicted for today as control and mop up continues on the fire. Clouds, cooler temperatures and rain will help fire operations and may reduce smoke production keeping most impacts close to the fire.  Although the moisture will reduce fire behavior, smoke in the nighttime and early morning hours may continue to follow the drainages, creating impacts.  Most of the smoke today will be above ground level from large logs and stumps that are still burning and smoldering.  There may be periods this afternoon when smoke is pushed by west/northwest winds so the communities of Westfir and Oakridge may experience impacts.
Smoke forecasts are dependent on predicted fire growth and weather.  If conditions change unexpectedly, impacts could occur.
