Air Quality Report for Southwest
Oregon Issued
for August 16, 2015
Rogue River-Siskiyou and Umpqua National Forests Time: 10:30am
Smoke Synopsis:
|
Yesterday:
Widespread light smoke
impacts across SW Oregon but did not exceed Moderate levels at any monitors.
Crescent Fire continues to be the leading smoke producer in SW Oregon with
contributions from Collier Butte and Stouts.
Today: Light wind speeds (<5mph) are expected
today and tomorrow. There will be a sense of directional flow missing for
smoke plumes. Therefore, smoke plumes will be influenced by terrain and
convective heating. The exception will be Collier Butte. Its smoke will
experience a northerly wind pushing smoke south while the Crescent and Stout
Fires will display more variability in plume directional spread. This creates
the opportunity for local smoke pooling and thus soupy conditions for next
two days. Burnouts will continue as weather and fuel conditions permit. Smoke
dispersion will depend on your location and shape of terrain. Tiller is
expected to be Unhealthy for Sensitive Groups, Shady Cove and Prospect areas
are projected at Moderate levels, while the rest of SW Oregon is projected at
Good Level. Crater Lake NP is being
impacted by Crescent Fire smoke at times, part of National Creek Complex.
Check NPS webcams for air quality status. http://www.nps.gov/crla/learn/photosmultimedia/webcams.htm
Tomorrow: Stagnating conditions and low
wind speeds will lead deteriorating air quality particularly in areas in
closer proximity to fire activity.
