A brush fire charred 300 acres Tuesday afternoon in a Moreno Valley field until Cal Fire aircraft slowed it down.
Two 5-acre fires were initially reported at about 1:20 p.m. in the area of Davis Road and Theodore Street, according to the Riverside County Fire Department.
The fires eventually combined into what firefighters are calling the Davis Fire, which quickly exploded to devour 300 acres. As of 3:30 p.m., the brusher was 5% contained, and the forward rate of spread had been halted.
No injuries were reported and no homes were threatened, fire officials said.
Eleven engine crews — totaling 75 firefighters — remained on scene, along with four Cal Fire air tankers and a single water-dropping helicopter.
The cause of the fire was unclear.
