Raging wildfires in Los Angeles have killed at least five people, destroyed hundreds of buildings and stretched firefighting resources and water supplies to the limit.

More than 100,000 people have been ordered to evacuate, while fierce winds have hindered firefighting operations and fuelled the fires.

The fires are already some of the most destructive in Los Angeles' history.

The largest fire consumed nearly 4900 hectares in Pacific Palisades, a picturesque neighbourhood between the beach towns of Santa Monica and Malibu that is home to many film, television and music stars.

Strong, dry winds fanned the Palisades blaze, and the area's narrow, winding streets, combined with the rush of thousands of people ordered to evacuate, created long delays and traffic jams.

Demand for water has caused some hydrants to run dry in Pacific Palisades after the last of three large water tanks in the area hit empty, officials said.

"We pushed the system to the extreme. We're fighting a wildfire with urban water systems, and that is really challenging," Janisse Quinones, chief executive of the Los Angeles Department of Water and Power, told a press conference.

California governor Gavin Newsom declared a state of emergency on Tuesday, and President Joe Biden pledged any help he could provide in his final days in office.
