Southern California is facing fierce fires fueled by the Santa Ana winds, which threaten homes and put firefighters to the test.

The Santa Ana winds are dry, powerful winds that blow down the mountains toward the Southern California coast. The region sees about 10 Santa Ana wind events a year on average, typically occurring from fall into January. When conditions are dry, as they are right now, these winds can become a severe fire hazard.

A rare Particularly Dangerous Situation warning has been issued for Southern California as a powerful and potentially damaging Santa Ana wind event​ is expected.

California Governor Gavin Newsom has deployed fire engines, water-dropping aircraft and hand crews across the region—to enable a rapid response if a new fire does break out, according to The Associated Press.

With the Palisades and Eaton Fires still not fully contained, another dangerous Santa Ana wind event is forecast in Los Angeles for Monday-Thursday.

The Santa Anas are expected to be most powerful Monday night into Tuesday. Fire services across the region say they are ready.

The National Weather Service issued a "particularly dangerous situation" alert for Los Angeles and Ventura counties as another dangerous wind event is expected this week.

Forecasters say a "moderate to strong'' Santa Ana wind event is expected, with isolated gusts of 80 to 100 mph expected in most wind-prone mountain locations, such as the San Gabriel, western Santa Monica and Santa Susana Mountains, according to the NWS.

More Santa Ana winds blew into Southern California Monday, again raising wildfire danger even as crews continued their efforts to fully contain a pair of massive blazes that erupted amid erratic winds earlier this month,

There is a 10% to 20% chance of flash flooding and landslides in some recently burned areas of Los Angeles County, forecasters say, including the Palisades and Eaton fire areas.

Answer: The Santa Ana winds have everything to do with weather. It starts with a high-pressure area over the Great Basin. That’s a huge area, spanning much of Nevada, Utah and parts of California, Idaho,

Some residents are slowly returning to their homes in the Pacific Palisades Monday, as containment of the deadly Palisades Fire has grown to 59% ahead of another dangerous Santa Ana wind event expected to bring isolated gusts as high as 100 mph Monday.
