Air Quality Report for Southwest
Oregon Issued
for August 11, 2015
Rogue River-Siskiyou and Umpqua National Forests Time: 9:30
Smoke Synopsis:
|
Yesterday: Light to moderate concentrations of smoke moved over
much of SW Oregon, and even Roseburg hit Moderate on the AQI scale. Thunderstorms
did not result in major impacts to existing fires. Fire growth did occur on
the National Creek, and Stouts Creek Fires with Collier Butte experiencing
the largest increase of about 1,000 acres.
Today: Thunderstorms remain a possibility for the National
Creek Complex. Collier Butte is expected to be the major smoke producer today
impacting the valleys and coastal area S of Gold Beach. The rest of the fire areas in SW Oregon can
expect similar local drainage weather effects facilitating a lazy dispersion
of smoke. As the inversion burns off, light west winds will develop in the
valleys. Upper transport winds will dominant from the S/SE facilitating smoke
contributions from California. Crater Lake NP is being impacted from National
Creek. Check NPS webcams for status. http://www.craterlakelodges.com/webcam/
Tomorrow: Smoke
levels indicate a slight improvement.
