Smoke
Outlook: Umpqua North/High Cascades
Complex
Issued for: Friday
September 1st, 2017
Air
Resource Advisor: Jen Croft, Aaron Wilkerson (T)
Fire
Activity: High Cascades is reported at 26,332 acres with 20 fires. Umpqua North is reported at 25,358 with 14
fires. Near record hot and dry conditions, combined with very dry woody
debris will contribute to an increase in fire behavior. A Red Flag Warning for
low RH has been issued. This will cause short crown runs, group torching, active flanking fires and
short-range spotting along uncontrolled perimeters. Burnout opperations to
protect values at risk will continue on the Umpqua North and Blanket Creek
fires. The combination of these conditions and activities will contribute to
visible smoke plumes.
Smoke: Winds out of the east will continue to provide some relief in
the morning hours. Mid-day, North winds are expected to move into the area. Northerly
winds will bring the smoke from the Umpqua North Complex down the Rogue
Valley into Medford. Smoke from fires along the East Cascades will move down
the Hwy 97 corridor and will settle into the communities of Diamond Lake,
Crater Lake, Chiloquin, Prospect, Shady Cove, and Klamath during the
evening/night time hours.
*The Oregon Department of Environmental
Quality has issued an Air Quality Alert in and around the outlook area and is
in effect until further notice. Wildfires burning in the region combined with
forecast conditions will cause air quality levels to fluctuate and could be
at unhealthy levels.
