Upper level monsoonal instability enhanced a hot and dry air mass at the surface to support steady fire spread in all fuel types. Fire growth was primarily a function of rapid uphill runs and roll-out due to steep, complex terrain. Better ventilation provided new growth opportunities along the south side of Trinity River. Western expansion continued with transport winds from the east during the first portion of the day transitioning to the west during the afternoon. Predominate fuel type is converted brush. Heavy dead and down components are dominant in many areas. All live fuels are cured to levels normally seen in late September.

Provide structure preparation, defense and point protection on identified values at risk within the Trinity River drainage. Prepare structures to receive fire. Scout control lines from previous fires for potential use. Construct direct and indirect containment line as appropriate and where safe to do so. Prepare for planned firing operations.

Fair relative humidity recovery will gradually reduce the fire spread during overnight hours. Daily diurnal wind flow will steer established, deep seated fire both east and west along the 299 corridor towards Junction City and Burnt Ranch.

The fire is burning in the footprint of the 2008 Cedar Fire. The terrain is extremely steep and access is difficult. Evacuation orders have been issued for residents of Del Loma and Big Bar on both sides of the Trinity River.

Forecast: Northwest winds will continue overnight with gusty up-canyon winds becoming

light down-slope overnight. Humidity recoveries will be poor to moderate. Isolated thunderstorms are possible again on Friday with dry lighting and gusty outflow winds possible.Very hot and dry conditions were experienced over the fire again today with

temperatures around 100° and humidities in the teens.

Observed: Thunderstorms

developed in NE California with some shower activity passing within about 50

miles of the fire area. Southeast upper-level winds in the morning shifted to the

northwest during the late afternoon with gusts up to 15 mph in the late

afternoon.

Better ventilation provided new growth opportunities along the south side of Trinity River. Western expansion continued with transport winds from the east during the first portion of the day. The fire is burning in the 2008 Cedar Fire, the 2012 Flat Fire, and 2015 River Complex burn scars. Predominate fuel type is converted brush. Heavy dead and down components are dominant in many areas.

Expect active burning as a robust warming trend extends burn periods. Daily diurnal wind flow will steer established fire both east and west along the 299 corridor.
