Air Quality Outlook
|
Yesterday afternoon
the South Fork Complex fire burned into heavy fuels producing a high smoke
column that was carried north by upper level winds into Morrow County. Smoke modeling indicates that the
source of elevated particulate levels in Baker was the Cougar Fire burning
south of Lewiston, ID.
Today and tomorrow,
an inversion will persist through late morning to early afternoon, holding in
any smoke accumulated over night in valley communities. Winds are expected to drive the South
Fork Complex fire into heavy unburned fuels producing significant smoke in
the mid to late afternoon both today and tomorrow. South to southeast winds will
push smoke towards Dayville, Mitchell, Paulina and possibly as far as
Prineville. John Day may see
moderate impacts from the Bald Sisters fire. Communities along the Deschutes River valley, especially Bend
and northwards, may experience hazy skies in the early evening for both
days.
Overnight, smoke
is expected to settle into valley communities near the fires such as
Dayville, John Day and Paulina.
