Seven crews are working on the La Sierra fire line. Three helicopters continue to support firefighting efforts on the ground by dipping water from Pena Blanca Lake to provide water drops from buckets suspended below the ships.
A thundershower yesterday evening raised humidity levels in the fire area last night and this morning but drying is expected to quickly diminish the moisture. High winds forecast for tomorrow bring the potential to increase fire activity.
The portion of the fire burning on Coronado National Forest lands east of Summit Motorway, west of Walker Canyon, and south of Ruby Road is approximately 4,800 acres. The fire’s growth reported in yesterday’s news release and today’s acreage reflects fire growth and the burn out operation being conducted to secure the fire perimeter. A large portion of the fire burns in Mexico.
The fire in Mexico is growing westward and threatens to cross onto Coronado National Forest lands west of Summit Motorway. Fire managers are developing contingency plans which might include expanding the fire perimeter westward towards Sycamore Canyon. The fire’s perimeter on the Coronado currently is 25 % contained.
Visitors should be aware that heavy truck traffic from incident vehicles will be encountered along Ruby Road and in the immediate area. Pena Blanca Lake is presently closed to the public as is the entire La Sierra Fire area between Sycamore Canyon and Walker Canyon south of Ruby Road. Both closures will remain effective until May 31st unless the restriction is lifted sooner.
