CalWood Fire Containment Increases on Tuesday; Red Flag Warning Wednesday
Current Situation: On Tuesday, both the CalWood and Lefthand Canyon fires were moderately active. Winds kept aircraft grounded in the morning, but aircraft were able to support suppression efforts in the afternoon when the winds died down. Crews constructed containment lines along the south side of the fire on Tuesday and conducted tactical firing operations on the southwest side of the fire to connect existing control lines. Firefighters also worked in the Highway 7 corridor and along the fire’s north edge constructing direct line and checking the fire’s progress to the north. Containment on the CalWood fire increased to 21% on Tuesday.
Today, dozers, engines, and hand crews will work on the southeastern side of the fire to build line as the fire backs down the hill towards Spruce Gulch. On the southwestern side of the fire, crews will continue tactical firing operations to connect sections of existing line and protect structures in the Balarat area. On the northeast side of the fire, crews will continue working on the canyon’s edge and in the Highway 7 corridor with the intent of keeping the fire south of Highway 7. Crews on the north side of the fire will continue constructing and patrolling fire lines.
Crews were able to get containment lines connected around the full perimeter of the Lefthand Canyon Fire on Tuesday. Those lines will be strengthened today. Firefighters assigned to the Lefthand Canyon Fire will be mopping up or removing heat from near the containment lines and patrolling for any spot fires that may cross established lines due to this afternoon’s winds. An increase in containment will come as those containment lines are secured to the point that firefighters are comfortable that the containment lines will hold.
Weather & Fuel Conditions: A Red Flag Warning is in effect for both fire areas from noon today until 8 a.m. Thursday morning due to gusty west-southwest winds and low humidity. Winds will be lighter in the morning across the fire area but will increase in the afternoon. As the day progresses, winds will shift to coming from the southwest and increase to 10-15 mph with gusts to 20 mph in Lefthand Canyon and 10-18 mph with gusts to 30 mph along the ridge tops. Relative humidity will be lower than yesterday at 18-25%, depending on location. Temperatures are expected to be in the high 60s in lower elevations and low 60s in higher elevations. An inversion layer will be in place over the fires again this morning and smoke from nearby fires may temper fire activity, as was the case on Tuesday.
