PALA, Calif. - Firefighters gained significant control Tuesday over the 350 acre Pala Fire with the help of morning marine layer.

As of Tuesday morning, fire crews had 60 percent containment on the fire, authorities said.

"Morning marine layer is reducing fire activity and is giving us a good chance to get in and engage the fire aggressively," Cal Fire spokesman Ray Cheney.

The Pala Fire broke out about 10:35 a.m. Monday near the intersection of Pala Temecula and Moro roads, according to Cal Fire Capt. Mike Mohler.

"The big challenge right now is the steep terrain which makes it very hard to access along with vegetation that hasn't burned since the late 60s," Cheney said.

There were no immediate reports of injury or lost structures but about three dozen homes in the vicinity of Rancho Heights and Magee roads were threatened Monday evening. No homes were reportedly damaged and all roads into the affected area were reopened Tuesday.

Red Cross officials closed the evacuation center at the Jim Banks Sports Complex at 12194 Pala Mission Road Tuesday after Cal Fire lifted the evacuation order.

Authorities said the fire, which remains under investigation, may have been sparked by a vehicle crash.

The California Highway Patrol reported on its website that a Toyota Camry hit a pole and caught fire about 10:30 a.m. Monday near the intersection of Pala Temecula and Moro roads.

The cost of the fire as of Tuesday morning was $404,000 and the fire is expected to be fully controlled by Wednesday evening , authorities said.
