Smoke Forecast for Umpqua North Complex -- Aug. 19, 2017

Fire
Given the low humidities and high winds, fire activity will increase today. 
 
Smoke
The local weather pattern looks to hold throughout the weekend.  Northeast/downslope winds in the overnight hours and north/upslope winds during the day.  The numerous small fires in the area are leading to a general haze that has been building over the last few days.
 
Smoke can be expected to move towards the south/southeast in the afternoon.  In the evening the smoke will drain down the valley of the North Umpqua River valley toward Glide.  Smoke for these fires is not expected to reach as far as Roseburg. 
 
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.
