A wildfire spread across brushy open terrain Tuesday in a hilly area of Barona, southeast of Ramona, charring about 20 acres, posing structural threats and prompting residential evacuations before crews gained the upper hand on the flames.
The blaze erupted for unknown reasons shortly before 4 p.m. off Wildcat Canyon Road, according to Cal Fire.
Within about 45 minutes, the flames had scorched 10 to 15 acres and were threatening homes along Barona Mesa Road, Calistoga Place, Moonglow Drive and San Vicente Road, the state agency reported.
Authorities advised residents of those areas to prepare to evacuate, and some of them cleared out of their homes to be on the safe side, Cal Fire Capt. Thomas Shoots said.
By 5:15 p.m., crews had halted the spread of the blaze, with no structural damage or injuries reported.
All evacuation warnings were lifted as of shortly before 6 p.m., Cal Fire advised.
The cause of the fire was under investigation.
