The Tick Fire in the Sand Canyon area of Santa Clarita grew more than 600 acres overnight as it destroyed 18 structures, burning through a total of 4,615 acres, authorities said Saturday.
Containment reached 55%, up from 10% on Friday night, authorities said, after several neighborhoods were repopulated following evacuations of 40,000 people. Some areas remain evacuated as more than 1,300 firefighters continue battling the wildfire.
Gov. Gavin Newsom declared a state of emergency for L.A. County after the fire scorched nearly 4,000 acres within just a few hours Thursday. It was first reported at 1:24 p.m. near 31656 Tick Canyon Road, according to the Los Angeles County Fire Department.
Newsom said the state has secured federal assistance to fight the fire, which has threatened 10,000 structures in recent days. In addition to those destroyed, the wildfire has damaged another 16 structures. Three injuries to firefighters have been reported, although details were not available.
Authorities said the following area remains evacuated:
- Tick Canyon Road from Abelia Road to Summit Knoll Road
Two evacuation centers had been operating for the fire at College of the Canyons Gymnasium at 26455 Rockwell Canyon Road and West Ranch High School at 26255 Valencia Blvd.
The Red Cross announced Saturday evening that the West Ranch High School shelter was closing as evacuations were slowly lifted. The shelter at the College of the Canyons remained open.
More than 900 firefighters remained assigned to the fire Saturday, with more at the ready in case they are needed, officials said.
Firefighters planned to make the most of favorable weather and low winds on Saturday night before another Santa Ana wind event was expected to blow through the area Sunday into Monday, authorities said.
The last remaining evacuations will be lifted as soon as it is safe to do so, incident commanders added.
