A brush fire burned 20 acres in east Chula Vista on Thursday morning, officials said.
Firefighters were called out to Mount Miguel and Proctor Valley roads in Chula Vista to battle what is being called the Miguel Fire, which started around 10:30 a.m.
The blaze was burning at a slow rate of speed, authorities said. By 11:30 a.m., the flames were spreading in light grass, heading downhill toward structures.
Firefighting aircraft were on the scene, aiding ground crews. An NBC 7 photographer at the scene saw two helicopters making drops, with hand crews on the ground on opposite sides of the fire.
By 11:45 a.m., firefighters had gained the upper hand, and the aircraft had made their final drops. No structures were damaged by the fire.
By 12:15, officials were tweeting that the spread of the fire had been halted, leaving just mop-up work for the firefighters on the ground.
