MURRIETA (CNS) - A fast-moving fire has burned upwards of 150 acres of brush in Murrieta, and was 40 percent contained by lines of cleared brush, the city's fire chief said Monday.
"We'll reinforce containment lines Monday," said Murrieta Fire Chief Matt Shobert.
More than 150 firefighters from Murrieta, Cal Fire, Riverside County and other agencies were working the fire lines in the hilly area overnight, said Shobert. Six air units, helicopters and tankers, worked until sundown and would return in the morning.
The fire -- named the Temprano Fire -- was reported at 4:45 p.m. near the 39300 block of Via Temprano, according to Riverside County fire officials.
"There are some damaged structures, including a fifth-wheel travel trailer and a barn-type structure, but no residences," Shobert said.
He said the fire moved fast because the thick chaparral "hasn't burned in decades."
Earlier Sunday, 100 to 200 homes were threatened and a voluntary evacuation center was opened at Vista Murrieta High School in the 28000 block of Clinton Keith Rd., but Shobert said there were no takers.
"People evacuated on their own or sheltered in place," Shobert said.
The threat has subsided with reduced nighttime temperatures and wind and increased humidity, he said.
No injuries were reported.
