A brush fire erupted Wednesday in a field near a campground and school in Banning, scorching about 30 acres and prompting evacuations as crews worked to encircle the brusher.
The non-injury blaze was reported at 2:20 p.m. in the 100 block of Westward Avenue, near San Gorgonio Avenue, according to the Riverside County Fire Department.
The agency said 22 engine crews, two air tankers and four hand crews from the county and neighboring Calimesa Fire Department were sent to the blaze and encountered flames moving at a moderate rate toward the KOA Campground, just west of Banning High School.
The school and campground were promptly evacuated. An evacuation warning was issued for residents in the area between Highway 243 on the south and Charles Street on the north, between South Hathaway Street and San Gorgonio Avenue.
Banning police officers closed Westward Avenue between 12th Street and San Gorgonio for public safety. Highway 243 between Old Banning/Idyllwild Road and Twin Pines Road was closed in both directions, according to Cal Fire.
Cal Fire water-dropping helicopters were sent to make runs on the brusher, but most air tankers were diverted to a much larger wildfire burning to the northwest, around Lytle Creek, in San Bernardino County.
As of 3:15 p.m., firefighters were trying to prevent the fire from spreading south into the San Bernardino National Forest.
The cause of the blaze was not known.
