Smoke
Outlook: Umpqua North Complex
Issued for: Friday August 25,
2017
Air
Resource Advisor: Jen Croft
|
Fire
Activity: Current size of complex is reported at 13,546 acres. Falls Cr, Happy Dog, and Devils remain the
primary sources of fire activity as resources continue to secure the
perimeter with burnout operations.
Moderate flanking fire and short uphill runs fuel by very dry
understory fuels.
Smoke: Very dry large woody debris is completely consuming and
producing small columns in the interior.
Aerial ignition operations are planned to assist in securing Happy Dog
fire when the visibility improves.
Smoke production during this suppression operation will be moderate
along the perimeter and interior voids of the fire area, moving off to the
east with minimal lift due to the limited transport winds available.
Tourists at Crater Lake National Park can expect to
see 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.
