Air Quality Report for Southwest
Oregon Issued
for August 17, 2015
Rogue River-Siskiyou and Umpqua National Forests Time: 10:30am
Smoke Synopsis:
|
Yesterday:
Once again
the smoke impacts across SW Oregon did not exceed Moderate levels at any
monitors with the exception of Eagle Point. Crescent and Collier Butte fires
are equally the leading smoke producers in SW Oregon with contributions from
Stout.
Today: Light wind speeds (<5mph)
continue. With no firm directional flow, smoke plume movement will be
dictated by terrain and convective heating. Best Air Quality will be from 1
pm to 6 pm. Collier Butte’s smoke affected by a north wind, will largely move
South. Crescent and Stout Fires display more variability in plume directional
spread. Thus creating opportunity for local smoke pooling and thus soupy
conditions. This is why Eagle Point & Tiller are projected to experience
the poorest air quality. Burnouts
continue as weather and fuel conditions permit. Smoke dispersion in the Hwy
199, 99, & I-5 horseshoe is dependent on your location and shape of
terrain. Crater Lake NP continues to
be impacted by Crescent Fire smoke at times. Smoke conditions can be seen by
viewing the NPS webcams for air quality status. http://www.nps.gov/crla/learn/photosmultimedia/webcams.htm
Tomorrow: Stagnating conditions and low wind speeds
will promote deteriorating air quality in areas in close proximity to fire
activity. This is seen for Shady Grove, Prospect, Tiller, and Brookings.
