The number of homes and other structures destroyed had reached 435. Damage assessments were continuing, with crews having to gain access to canyon areas on foot.

“That number is going to rise significantly,” Los Angeles County Fire Chief Daryl Osby said.

Residents who stayed behind in coastal communities that were cut off by road closures were getting supplies by boat. Gas, food, baby wipes and horse pellets were among the items brought ashore in the Paradise Cove area of Malibu.

“It’s pretty cool. It’s really amazing that people out there know that we’re kind of stranded here in Malibu,” Cherie Millford Smart said.

Large boats arrived from Redondo Beach, about 25 miles to the south. Supplies were unloaded onto smaller boats, jet skis and even surf boards. Some residents donned wetsuits and swam ashore with cases of water and beer.

Miley Cyrus and Liam Hemsworth lost their Malibu home in the wildfire and are donating $500,000 to The Malibu Foundation through Cyrus’ charity, The Happy Hippie Foundation.

A statement from the couple says they “are very grateful to be safe along with their animals.”

The fire has grown to 150 square miles, but containment also increased to 35 percent.

The fire has burned more than 80 percent of National Parks Service land in the Santa Monica Mountains National Recreation Area.

Authorities lifted evacuations Tuesday in several neighborhoods, and other areas have been repopulated since the weekend. Tens of thousands of people remained under evacuation orders, down from a high of as many as 250,000.

Los Angeles County Sheriff Jim McDonnell urged patience by residents being turned back at roadblocks.

The area has not seen such a firestorm since the Old Topanga fire of 1993. The firestorm has left an array of hazards, including trees ready to fall, downed power lines, toxins, water main and gas leaks, and other destroyed infrastructure.

“We want to get you home but more important we want you to be safe,” McDonnell said.’

Forecasts called for the Santa Ana winds to lighten Wednesday and Thursday. A forecast of possible rain next week would help firefighters but also raised the prospect of potential mud flows, Osby said.

At least 42 people were confirmed dead in a wildfire that obliterated the Northern California town of Paradise, making it the deadliest wildfire in recorded state history. The search for bodies continued.

The cause of the Southern California fires remained under investigation.

Southern California Edison said last week that it reported to the California Public Utilities Commission “out of an abundance of caution” that there was an outage on an electrical circuit near where the fire started Thursday but there was no indication its equipment was involved in the fire reported two minutes after the outage.

Downed power lines and blown transformers have been blamed for several of the deadly fires that have burned in recent years.
