Dixie Fire Update for Tuesday, August 3, 2021
Lassen and Plumas National Forests, August 3, 2021 — Extreme fire behavior is predicted today, with an Incident meteorologist declaring a local Red Flag Warning for single-digit relative humidity on the Dixie East Zone and Evans fire area from 2:00 – 7:00 pm. Active fire with uphill runs, single tree torching, and spotting is expected. Winds and fire activity are expected to test established firelines on the perimeter. Evacuation zones have changed with new mandatory areas in Plumas County. Residents in Evacuation Warning areas should stay alert to conditions and remain prepared.
Active fire and smoke columns will be visible. Communities north of the fire, including Chester, Mineral, and Susanville, will have unhealthy and very unhealthy levels of air quality this afternoon.
The Dixie Fire is approximately 253,052 acres with 35% containment. There are roughly 5,168 fire personnel assigned to the incident. The incident remains in Unified Command, with two teams overseeing the fire. CAL FIRE Incident Management Team 1 is on the West Zone. California Interagency Incident Command Team 2 is on the East Zone and transfers command to California Interagency Incident Command Team 4 at 7:00 pm today.
On the East Zone, the focus will be on attacking the fire advancing north from Round Valley Reservoir with aerial resources, heavy equipment, handlines, and structure protection. Firefighters are working today on securing and monitoring fire advancing towards lines in Bucks Lake Wilderness. During yesterday’s wind event, other areas of the fire perimeter held and will be monitored closely today as winds continue. The Evans Fire is holding within the current perimeter.
On the West Zone, fire behavior is expected to increase due to drying conditions. Fire continues to move towards control lines burning unburned interior islands and ridges. Steep terrain, heavy fuel loading, and wind in alignment with canyons is making control difficult. Forecasted weather patterns remain steady with no big weather changes, though conditions remain near critical with breezy, hot and dry weather today. A dry cold frontal passage will bring a wind test to the fire late Wednesday into Thursday before a quieter weather pattern returns. Fire crews continue to construct and reinforce control lines, fall trees that threaten containment efforts, and provide structure defense in communities at risk.
The public is encouraged to stay tuned to the latest fire information. Be prepared by having a full tank of gas, collecting important documents and medications. For additional tips, visit https://www.readyforwildfire.org/.

Fuel moistures are historically low, ERCs and BI are in the 97-99%
Single Tree Torching
Fire stayed active overnight. Short range spotting, uphill runs and single tree torching have challenged crews.
Construct direct and indirect line to secure fire perimeter. Construct contingency lines
in both zones. Provide structure defense in communities at risk: Chester, Hwy 36 corridor, Paxton, Greenville, Jonesville,
Crescent Mills, Taylorsville, Canyondam, Butte Meadows, Bucks Lake, Meadows Valley, Rush Creek and Greater Alamnor area. Continue tactical patrol in the communities impacted by fire.
|Projected Incident Activity|
Fire behavior expected to increase due to drying conditions. Fire continues to move towards controls lines burning unburned interior islands and ridges. Steep terrain, heavy fuel loading, and wind in alignment with canyons is making control difficult near div M and N break. On the West Zone fire is actively burning in division L after spotting across the control line. It is currently threatening structures along the Hwy 36 corridor. On the East Zone expected area to grow is
division N, O, and X within the Bucks Wilderness area.
California Interagency Incident management Team 4 (CIIMT 4) is shadowing CIIMT 2 today and will transition today

Observed: Hot conditions continued across the Dixie East Zone and Evans Fire areas this afternoon with temperatures in the mid-80s to
upper 90s. Afternoon humidity values have continued to plummet down into the teens with general west to south southwest wind gusts ranging between 15 and 25 mph at elevations above 3,000 feet.
Forecast: Through the afternoon, humidity values will likely fall down to near 10 percent for many locations. A handful of areas may see single digit relative humidity readings with hot conditions and temperatures in the upper 90s to near 103 degrees at lower elevations. General West winds will likely gust as high as 28 mph, especially in areas where the terrain aligns with the winds. Relative humidity values between 8 to 15 percent can be expected through the early evening before RH rebounds into the 20 to 40
percent range. Locations in canyons and valleys will likely be sheltered and wind speeds overnight should settle down below 8 mph. A better defined thermal belt than has been reported in past nights is expected tonight into the pre-dawn hours on Tuesday and areas that are exposed at mid-slope and at higher elevations may experience southerly winds of 8 to 12 mph. Gusts to near 15 mph are possible.
Seasonable weather pattern continued across the region today with southwest winds blowing in the afternoon as humidity lowered to the mid teens with highs in the 90s. Winds ease after dark with light downcanyon setting up overnight. Continued poor humidity recovery to only around 40% towards sunrise. Forecast pattern remains steady
for Tuesday with no big weather changes though conditions remain near critical with breezy, hot and dry weather Tuesday afternoon. A dry cold frontal passage Weds afternoon and evening will bring a wind test to the fire as stronger winds and instability aloft will test containment lines later Weds into Thursday before a quiet weather pattern returns.
