A brush fire along Highway 243 in the San Bernardino National Forest south of Banning was holding at 33 acres Friday, and was just about fully contained.
The non-injury Edna Fire was reported at 3:40 p.m. Thursday in the area of Highway 243 and Mount Edna Road, according to the Riverside County Fire Department.
