Extreme fire conditions remain in the Southern California region as high winds have prompted a "Particularly Dangerous Situation" red flag warning,​ weather officials say.

Santa Ana winds are caused by strong high pressure over the Great Basin region of the West creating a pressure gradient that amps up winds through the mountains, foothills and sometimes valleys of Southern California. In this case, the winds are getting a major boost from a strong upper-level low pushing southward across the state.

Another round of fire weather could last for much of next week in Southern California, bringing new dangers as Pacific Palisades, Altadena and surrounding communities struggle to assess the damage of devastating wildfires earlier this month.

At least 24 people are believed to be dead and many more injured as several fires broke out across Southern California amid historically dry and windy conditions.

More than 20,000 donors have given a total of $14 million to the nonprofit California Community Foundation to support recovery efforts prompted by the Southern California wildfires, Los Angeles Mayor Karen Bass said.

Santa Ana winds in Southern California are often-fierce winds that topple power lines and trees and can turn a spark into a raging wildfire.

The winds fueling Southern California wildfires form when a high-pressure system develops over the Great Basin in Utah and Nevada
