Air Quality Summary August 12, 2013
Incident: Big Windy Complex Wildfire
Saturday’s rains resulted in a significant reduction of fire activity in SW Oregon on Sunday and air quality was Good to Moderate over the entire area. A few data processing glitches lead to some delay in obtaining data from a couple of the monitoring stations, but this seems to be resolved now. Northern California fires (Salmon River Complex, Corral Complex, and the Butler Fire) were active yesterday afternoon and some smoke (mostly aloft) from those fires was over Oregon this morning.
Average concentrations of fine particulate matter (PM2.5) from yesterday, August 11 (midnight-midnight), are shown in the documen to the right under "Related Information".
Air Quality Forecast: Only moderate amounts of smoke are expected today with perhaps some greater amounts in areas close to each of the complexes if burnouts are conducted this afternoon. Tonight, smoke can be expected in the primary river valleys, dispersing mid-late morning on Tuesday. Additional burnouts are planned Tuesday and Wednesday as the fine fuels dry out following the weekend’s rains to reduce the potential of fire growth outside of containment lines. This will result in a decrease in air quality over the entire region, especially in areas north, east, and south of the fires in the afternoons, and down the river valleys to the west late nights and early mornings.
