2016

John Washington (jwashington@fs.fed.us)
FIRE, WEATHER AND SMOKE SYNOPSIS
Weather: Drier conditions will be seen
today, with a slight chance of afternoon high level clouds. An upper level
disturbance will leave the area today as an upper level ridge begins to build
in the area. The ridge will bring a warming and drying trend over the next
few days. Wind speeds will be relatively weak near the surface and aloft with
transport winds primarily out of the west this afternoon. Up-canyon winds will be around 4 – 8 mph, while
ridge winds will be 7 - 10 mph with gusts to 15 mph over exposed ridges. Inversion will break between 11am and 1pm.
Over next few days expect the ridge to strengthen and bringing warmer and
drier conductions supporting increase fire behavior.
Fire Activity: Increased
temperatures, and lower RH values will increase fire activity this afternoon. The most active fire activity will be seen
north of HWY 17 and HWY 21 in the Clear Creek, Deadwood, and Bear Valley
drainages. Relative humidity (RH) values will be around 25 – 30 percent in
lower valleys and 35 – 40 percent in high elevations. Grass and shrub fuels will be active for
uphill runs in valley locations.
Wind/slope alignment may result in moderate spread rates; however
significant spread rates are not expected due to low-level moisture and weak
winds.
