Air Quality Report for Southwest
Oregon Issued
for August 12, 2015
Rogue River-Siskiyou and Umpqua National Forests Time: 10:30
Smoke Synopsis:
Yesterday: Widespread smoke impacts remained in SW Oregon but
most areas did not exceed Moderate levels. Shady Cove and Tiller areas continue
to be impacted by smoke from the Stouts Creek fire. Fire growth and smoke
production on the Crescent portion of the National Creek Complex necessitated
the closure of Highway 230 from mile marker 12-24.
Today: National Creek Complex is expected to be the major
smoke producer today with contributions from Collier Butte. Valleys will be
impacted at a Moderate AQI again. Wind speeds are increasing facilitating better
dispersion through the day. As the
inversion burns off, moderate west winds will develop in the valleys and
should push smoke out. Upper transport winds will continue to dominant from
the S/SE facilitating additional smoke contributions from California fires. Crater Lake NP is being impacted from
National Creek Complex. Check NPS webcams for status. http://www.nps.gov/crla/learn/photosmultimedia/webcams.htm
Tomorrow: Meteorology
indicates potential for some improvement. Surface and upper air wind speeds
will lead to much better dispersion conditions. These better smoke dispersion
conditions could be offset if winds cause existing wildfires to grow faster
or larger than expected; or if new fires start.
