Update (Aug. 16)
Overcast conditions, cooler temperatures and some precipitation led to decreased wildfire behaviour being observed on the Flat Lake fire Monday, according to BC Wildfire Service.
Danger tree assessments and falling will occur Monday after the cold front passed through the fire, BC Wildfire said in its latest update for the northeast complex.
It noted heavy equipment has constructed a fuel-free guard along the west flank of the excursion and will focus efforts on widening this newly built control line and pre-existing roads to further secure the area. If conditions are suitable, small scale hand ignitions will occur tight to the line to remove unburned fuels.
Temperatures are expected to be cooler with highs in the mid to upper teens and increasing cloud. An upper low will pass through southern B.C. on Tuesday keeping cloudier conditions, with winds from the north to the northwest before an upper ridge moves over the area on Wednesday, bringing a return of warmer and drier conditions with highs in the low to mid-20s.
BC Wildfire said heavy equipment was working on securing an “excursion” in the Flat Lake fire by continuing to establish a fuel-free guard around this area and tying into pre-existing roads.
Skimmers supported these efforts Saturday, Aug. 14 by cooling down hot spots while equipment worked to put in line along the top of the excursion.
“The wildfire did cross our containment line on the northern flank of the fire near Moose Valley Park on Aug. 13,” the latest update said. “There continues to be spread in a north/northeast direction.”
Efforts will continue on re-establishing and widening control lines in place along the Snag Lake road to the north Moose Valley Park and east of the park along the 1100 road, while planes and helicopters will also work to re-enforce the already established guard on the western portion of Edmunds Lake Road in preparation of the anticipated cold front, according to the update.
“This is being done pre-emptively and not due to the fire reaching this control line,” the update states.
On the northeastern corner, firefighters will continue to utilize direct attack methods to secure the fire’s edge by patrolling and extinguish hot spots from 87 Mile to 83 Mile. On the southwestern flank, firefighters will continue to conduct mop-up operations on the southwest corner and up the west flank to patrol and extinguish any hot spots found.
The Flat Lake wildfire is estimated to be 68,551 hectares in size.
BC Wildfire and the District of 100 Mile both state there is no evacuation alert in 100 Mile House.
More to come.
