Air Quality Outlook
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.
