All evacuation orders were lifted, as the Tick Fire was 70% contained on Sunday evening, the Los Angeles County Fire Department said.
Dangerous fire weather conditions and Santa Ana winds were expected to return to much of the Los Angeles and Ventura counties, authorities said.
The fire in the Sand Canyon area of Santa Clarita burned through a total of 4,615 acres as of Sunday, according to a multiagency update released Sunday.
The tally of destroyed and damaged homes continued to climb as inspectors were able to better access the burn area.
A total of 42 structures have been destroyed by the Tick Fire, including 36 homes, 2 commercial structures and 4 outbuildings, officials said. Another 29 buildings were damaged, including 24 homes, 1 commercial structure and 4 outbuildings.
With a new round of Santa Ana winds coming in on Sunday, red flag conditions were expected to return to the Tick Fire burn area, the Los Angeles County Fire Department said. Any new fire ignitions have the potential to spread fire very rapidly, they said.
“We’ll be prepositioning strike teams, staffing extra firefighters on our engines to have the most robust response should an ignition occur so we can get as many firefighters on that as early as possible," said fire Capt. Tony Imbrenda.
The gusty Santa Ana winds were expected to develop on Sunday afternoon and last through Monday, along with low humidity, according to the National Weather Service. Peak wind gusts are expected to range from 40 to 60 mph, the weather service said.
Firefighters took advantage of the lower winds, cooler temperatures and higher humidity before the winds set in, to maintain a high operational tempo to increase containment of the Tick Fire.
“What we’re doing here today is getting the best control measures in place that we can so that we don’t have any kind of a rekindle on this incident," fire Capt. Imbrenda said. "Then we’re going to be prepositioning resources in our high threat areas, along the I-5 corridor, where we’re working right now along the Angeles Front Country in the La Crescenta and La Canada Flintridge area, and then of course along the Santa Monica mountains.”
More than 900 firefighters remained on-scene at the Tick Fire Sunday, with more of them ready should further need arise, officials said.
Four firefighter injuries have been reported during the wildfire.
All evacuation shelters, including the College of the Canyons gymnasium and West Ranch High School, are now closed.
The Castaic Animal Care Center remains open for animals.
The Los Angeles Unified School District announced that campuses that were closed due to the fires would be back open Monday.
"After-school programs will be in session. Outdoor activities may be limited, depending on conditions," the LAUSD said via social media.
