Smoke Forecast for High Cascades Complex Fires (Including Blanket Creek, Broken Lookout, Spruce Lake) -- Aug. 21, 2017
Smoke
Outlook: High Cascades Complex
Issued for: Monday, August 21,
2017
Air
Resource Advisor: Jen Croft
Fire
Activity: Continued internal smoldering and large woody debris will
contribute to the visible smoke in the geographic area. Blanket fire grew an additional 220 acres,
Broken Lookout added 383 acres, Sherwood 2 grew six acres, and Spruce Lake
filled in an additional 38 acres of its identified perimeter. The remaining fires within the complex have
been fully contained and two of the fires reached controlled status.
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. Highest areas of smoke concentrations for
Monday evening will be Prospect, Chemult, Chiloquin, and campgrounds near
Crater Lake.
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
