BANNING , Calif. (KTLA) — Firefighters on Monday continued to battle a brush fire in the mountains north of Banning in the San Bernardino National Forest.
The blaze, dubbed the Hathaway fire, has charred 1,500 acres and was 15 percent contained.
It was first reported just before noon on Sunday on the northern portion of the Morongo Indian Reservation.
The fire was burning in steep, rugged terrain in the San Gorgonio Wilderness, according to the U.S. Forest Service.
No homes were threatened, officials said.
About 1,000 personnel were assigned to the blaze, assisted by nine air tankers and eight helicopters.
Officials warned that smoke would continue to be visible during active burning periods in mountain communities.
A high pressure system was expected to build in the area on Tuesday and Wednesday, bringing high winds and lower humidities.
The cause of the fire remained under investigation.
