Air Quality Summary August 19, 2013
Incident: Big Windy Complex Wildfire
Sunday’s air quality levels at the SW Oregon monitoring locations averaged at Good to Moderate levels over the 24-hr period. The day was characterized by short periods of poor air quality followed by clearing (or the reverse, depending upon your location). The upper Rogue Valley above Shady Cove saw smoky conditions generated by the Whiskey Fire in the morning which cleared as temperatures warmed, while the Illinois River valley near Cave Junction was clear in the morning, but was impacted by smoke from Big Windy and Douglas Complexes late in the afternoon. The Rogue valley below Galice has seen smoke mornings, afternoons and nights with periods of clearing. Overnight, gusty winds from the northeast helped to keep the smoke from pooling in many of the lower river valleys.
Air Quality Forecast: Burnout operations are winding down at the Douglas Complex, although the natural “unassisted” burning will continue with windy and dry conditions. Burnouts along the southeastern portion of the Big Windy Complex are scheduled to continue today as well as in the eastern areas of the Whiskey Complex. Expect smoke today to drift to the south from these locations and tonight to the southwest from Big Windy and Douglas and to the southeast from Whiskey. Gusty winds may keep smoke from concentrating as densely as it has in recent nights in many of the valley locations. However, Elk Creek and the Rogue River valleys above Shady Cove as well as the Rogue valley below Galice and the Illinois valley in Josephine County will still see some thick smoke in the late night and morning hours.
