The wider Pacific Palisades neighbourhood is known as an upscale celebrity haunt. Schitt’s Creek actor Eugene Levy is among those who have been forced to leave their homes – and others, including Tom Hanks and Jennifer Aniston, have reportedly had to do the same.
The other two fires are burning above Altadena, near the Eaton Canyon, and in the Sylmar suburb, where a mandatory evacuation has been ordered as flames spread rapidly.
More than 1,400 firefighters have been deployed to combat the “unprecedented” blazes, California Governor Gavin Newsom said earlier.
Fire ecologist Chad Hanson predicted “a rough night” for fire crews, with the most extreme conditions expected from 02:00-06:00 local time (10:00-14:00 GMT).
Mr Hanson said January was still considered to be wildfire season in this part of California, and that the biggest influence were the Santa Ana winds.
“These winds are unique to southern California,” he said, explaining that they result in” extreme, sustained wind events with pretty dramatic gusts.”
