The fire generally remains within the 2006 Pigeon Fire and 2015 Happy Fire scars, as well as the 2008 Cedar, Eagle, Miners, and Buckhorn Fire footprints. Type 5 converted brush and a heavy dead and down component dominate most areas. All live fuels are cured to levels normally seen in late September.
Fire behavior was active due to exceptionally low fuel moistures both live and dead after the inversion broke and overnight RH recovery dissipated around 3 pm. The fire remained mostly smoked in for the bulk of the shift.
The fire actively flanked west into the wind above the Hyampom Road and continued to actively burnout pockets of green fuels inside of the control lines north of the Hayfork Creek drainage both from firing and flanking of the main fire.
The NW side of the fire entered the burn period about 1 hour ahead of schedule due to clear air and brisk NW ridge top winds. The fire actively flanked and backed into the New River drainage through both burnout operations and main fire spread. On the NE portion of the fire, spread in the drainage between Limestone and Backbone Ridge was checked by NNW winds but remained active.
Smoke cleared from this area around 3 pm when terrain driven winds switched to down canyon.
Secure fireline along Backbone ridge. Contain slopover in division L. Implement defensive firing operations along the 3N08 road in division Y. Continue prepping, firing, and holding along the Denny road. Continue structure defense in division U. Hold, improve, and patrol existing containment lines in divisions W/Z.
Observed: A lot less smoke was over the fire to start the day off on Friday allowing inversions to break one to two hours earlier than previous days. High temperatures also responded to the additional sunshine with highs near 90 across the lower elevations of the fire and near 80 in the upper elevations. Winds were mainly westerly at ridgetop and terrain driven below ridgetop. Humidities dropped into the teens in most locations across the fire.
Forecast: Gusty southwest winds at higher ridgetops ahead of a trough of low pressure that will arrive on Saturday. Winds on Saturday will be from the southwest gusting up to 20 mph in the afternoon and up to 30 mph during the late evening. Mostly cloudy skies will keep the high temperatures down and relative humidity up. The chance of rain increases in the afternoon with the northern parts of the fire the most likely location to pick up some rainfall. The chance of rain continues through Sunday morning before skies clear late Sunday. Temperatures below freezing will be possible Sunday night.
