Smoke
Outlook: Whitewater Fire, Willamette NF
Issued
for: Saturday, August 5, 2017
Air Resource Advisor: Duncan
Leao (dleao@fs.fed.us)
Smoke:
Some lingering smoke will be visible in the
vicinity of the Whitewater fire and surrounding drainages earlier in the day. The morning inversion will begin to lift
around noon and smoke from the fire is expected to drift to the east and
northeast in the afternoon causing a slight improvement in air quality for
Detroit area. A light southwest wind may push smoke into Warm Springs, Madras,
and Sisters. Smoke dispersion is not
expected to be good due to a more stable atmoshpere. Expect downslope/down canyon
settling of smoke around Detroit and Breitenbush during the evening. Smoke impacts may shift to the west
tomorrow due to changing weather.
Fire:
The fire grew approximately 200 acres yesterday for
a total of 5,000 acres. Fire activity today
and tomorrow is expected to remain similar to yesterday. Temperatures will be slightly cooler,
however west and southwest winds may align with local upslope/upcanyon winds
to push the fire spread east. Isolated
torching and minor spotting could occur today.
