South Fork Complex Air Quality Outlook 8/11/14 ^NH

Yesterday saw active fire behavior in the South Fork Complex fire. Smoke lingered the nearby valley communities including John Day, Dayville, and Prairie City.
Today’s southeast winds will push the northwest perimeter of the South Fork Complex fire into unburned timbered fuels creating additional smoke throughout the day. While a light morning inversion will lift late this morning, light to moderate smokey conditions are likely to persist off and on in nearby communities throughout the day (including John Day, Dayville, Prairie City, Paulina and Mitchell). Smokey conditions in Burns will lift by late morning/early afternoon. Smoke may settle back into Burns tonight. The potential for thunderstorms to pass over the area may result in local wind gusts that could result in greater fire activity this afternoon and additional smoke.
Tomorrow will see similar air quality conditions in communities around the South Fork Complex fire. Winds will shift and come from the southwest affecting nearby downwind communities throughout the day (including John Day, Dayville, Prairie City, Seneca and Unity). Burns will once again see smoke impacts in the morning, clearing by early afternoon. Smoke from Northern CA fires could drift into the Deschutes River valley communities including Bend, Madras, Prineville, Redmond and Sisters. Paulina and Mitchell may also see smoke effects from the Northern CA fires.
