Timber (Grass and Understory)
Brush (2 feet)
Short Grass (1 foot)

Historically dry fuel conditions are contributing to extreme fire behavior.

Moderate
Torching
Crowning
Running

Steep terrain, and heavy timber hampering suppression efforts. Fire is moving North, Northeast.

Combination of direct and indirect dozer line.

Fire will continue to spread northeast towards Mount Hough and spreading east, towards the town of Quincy with possible evacuations.

Observed: Southwest to west winds persist late this afternoon
(Saturday) with peak gusts between 15 and 20 mph on area RAWS. Afternoon humidity has fallen down between 10 and 20 percent in spots. Widespread dense smoke and haze has likely kept temperatures in the mid to upper 80s at higher elevations and mid to upper 90s for locations below 5,000 feet. Radar imagery detected smoke columns likely associated with pockets of intense heat/fire activity near Bucks Lake, the Indian Falls area and along the Fly Fire.

Forecast: Afternoon humidity will continue to fall down to below
10% in many areas with breezy west winds of 10 to 15 mph with
gusts to near 22-25 mph. Dense smoke and haze will likely linger
through the remainder of the day which will keep afternoon
temperatures from getting much over 102 degrees. Smoke columns
will likely persist through the afternoon, with a non-zero lightning risk. Gusty and erratic winds can be expected with column
collapses.

Tonight, dense smoke and haze will continue, especially in any of the valleys, sheltered areas and/or drainage basins. By 2300 LT, winds across much of the area should subside to below 10 mph, with down-valley and downslope flows becoming well established by 0200 LT. Overnight humidity recovery will improve compared to
Friday Night/Saturday morning, but values tonight into Sunday are still expected to remain critical. Max RH will range between 15 and 35 % with higher RH recovery in the valleys, sheltered and drainage areas.

Sunday has the potential to be hot, dry and breezy along with dense smoke across most of the Dixie Fire. The threat for smoke columns reaching pyro-cumulus status will increase with isolated lightning strikes becoming an increasing possibility. Strong, gusty and erratic winds can be expected in the vicinity of pyro-cumulus.
