Air Quality Report for Southwest
Oregon Issued
for August 14, 2015
Rogue River-Siskiyou and Umpqua National Forests Time: 11:30
Smoke Synopsis:
|
Yesterday:
Widespread smoke impacts remained
in SW Oregon as AQ remained mostly at Moderate levels. Shady Cove and Tiller
areas continue to be impacted by smoke from the Stouts Creek fire. Crescent
Fire continues to be the leading smoke producer for SW Oregon with contributions
from Collier Butte and Stouts. Willamette Valley areas including Roseburg and
Eugene area also at Moderate levels yesterday.
Today: Smoke dispersion will be better than yesterday as westerly
winds dominant. Changing wind direction is expected to dilute the smoke and prevent
high level AQ impacts. There is a concern for increased fire growth and smoke
production from planned burnouts. Areas near and downwind of wildfires may experience
Unhealthy or USG AQ levels. Crescent Fire in Crater Lake NP is the major
smoke producer. Upper transport winds
will start with a SW flow shifting to a Westerly flow. Crater Lake NP is being impacted by Crescent Fire, part of National
Creek Complex. Check NPS webcams for status. http://www.nps.gov/crla/learn/photosmultimedia/webcams.htm
Tomorrow: Meteorology
indicates potential for more tranquil winds as the North flow dominates. Generalized
soupy smoke conditions continue with possible elevated AQ levels in Klamath
Falls, Shady Grove and Prospect. Surface and upper air wind speeds will not
be as strong and smoke accumulations will not clear out quickly.
