Smoke Forecast for Umpqua North Complex Fires -- Aug. 21, 2017

Smoke Outlook:  Umpqua North Complex                                
Issued for: Monday, August 21, 2017 
Air Resource Advisor: Jen Croft


Fire: Active fire spread between the three segments will continue to provide for firefighter safety.  Good progress is being made with the additional small fires within the complex, showing limited fire growth.  Periods of ESE winds and unstable airmass will provide opportunities for additional fire growth today. 

Smoke: The arrival of ESE winds in the morning will bring a chance of clearing conditions during the eclipse event, pushing stagnant haze into a mixing wind.  WNW winds are expected to return in the afternoon along with an unstable air mass which may allow for some additional fire activity and smoke production.  Late afternoon conditions will see the return of widespread geographic haze around 1pm as the N-NE winds push smoke from the Umpqua North and HWY 97 corridor back into the area. 

Tourists at Crater Lake National Park will be able to view and smell smoke. Visitors should check for road closures and other announcements ahead of time.  Visitors can check https://www.nps.gov/crla/planyourvisit/conditions.htm for updates.
