The additional fatality was attributed to the Palisades Fire, officials said.
At least 29 people have died as multiple wildfires, fueled by severe drought conditions and strong winds, rage across Southern California.
Thousands of firefighters have been battling wildfires across 45 square miles of densely populated Los Angeles County. The two largest fires, the Palisades Fire in Pacific Palisades and the Eaton Fire near Pasadena, remain active. One of the latest, the Hughes Fire in the Castaic area, has prompted evacuation orders for tens of thousands of people.
ABC News has kicked off "SoCal Strong" (#SoCalStrong), highlighting the impacted communities and offering fundraising opportunities for victims of the fires. The coverage will continue across multiple ABC News programs and platforms.
The Palisades Fire, which began in the Pacific Palisades on Jan. 7, has destroyed or damaged more than 6,000 structures. It's covered more than 23,000 acres and is at 87% containment.
The Eaton Fire north of Pasadena also began on Jan. 7 and has destroyed or damaged more than 10,000 structures. It's burned over 14,000 acres and is at 95% containment.
The Eaton Fire, which destroyed blocks of homes in Altadena, is now 55% contained.
The Eaton Fire has damaged or destroyed 7,000 structures, making it the most destructive fire in Los Angeles history and second-most destructive in state history.
Officials giving an update on the Palisades Fire on Wednesday said they have generated more than 150 leads as they probe the cause and progress of the blaze.
Jose Medina, acting special agent in charge of the ATF Los Angeles Field Division, said investigators are scouring video from state owned cameras that were in place in the area, from residents in the area and from social media posts.
Investigators have conducted interviews with individuals that initiated the 911 calls and the first responders to the Jan. 7 blaze, as well as the fire that was started in the area and put out on Jan. 1, he said.
Medina appealed to any hikers who were on nearby trails around Skull Rock on the morning of Jan. 7 to contact investigators. "We are talking to individuals about not just what they saw, but what they smelled and they heard," he said.
"Even if you were in the area and saw or smelled nothing that too could be valuable information," Medina said.
Asked if rekindling of the Jan. 1 fire appeared the most likely cause, Medina said investigators "are not leading towards anything right now. We're taking everything in evaluating all the evidence we received, but it's too early on in the investigation to make any determination."

These winds will wind down by Wednesday evening. The winds will be much calmer Thursday and Friday.
Urban search and rescue workers are using rakes to move debris as they search for human remains along the Pacific Coast Highway where homes were destroyed by the Palisades Fire.
