The fire on Tuesday intensified on the east and west flank as air tankers and helicopters assisted firefighters on the ground in the area of Pine Bench. Hand crews and bulldozers worked above them across the Yucaipa Ridge to build a fire break in an effort to protect the areas of Forest Falls and Oak Glen.

Overnight, the fire is expected to remain active and burn toward Oak Glen as fire crews work to keep the blaze on the west side of the drainage area.
