Smoke Forecast for Umpqua North/High Cascades Complex Fires -- Aug. 30, 2017

Smoke Outlook:  Umpqua North/High Cascades Complex        
Issued for: Wednesday 30, 2017 
Air Resource Advisor: Jen Croft, Aaron Wilkerson (T)

Fire Activity:  High Cascades is reported at 22,692 acres. Umpqua North is reported at 20,924. The Happy Dog fire is now the biggest threat to several communities:  2 miles southwest and 3 miles northwest of Soda Springs; 2.5 miles southwest of Slide Creek; and 5 miles west of Toketee Ranger Station. Lines are being constructed to prevent this spread from impacting powerlines and highway 138. Burnouts are likely to begin within the next 24 hours. Hot weather, low humidity, and dense smoke are impeding efforts and there have been no opportunities for air support due to poor visibility.
Wednesdays weather is expected to increase acreage on all uncontrolled fires and contribute to widespread unhealthy air quality within the region.

Smoke: Winds will start out fairly light from the NE to SE direction.  By afternoon they will shift W to NW with gusts developing by late afternoon, especially over higher terrain. This will push smoke east and again greatly impact the Rogue Valley, Cascades and communities along the east side of the Cascades. These westerly winds may provide some relief to Roseburg, Glide and Medford. 
*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.
