Southern California is braced for "extremely critical fire conditions" caused by a new period of Santa Ana winds today through Wednesday across parts of Los Angeles and Ventura counties, as the battle to contain rampant blazes goes on.

Firefighters braced for high winds, with the National Weather Service of LA issuing its most serious advisory, “Particularly Dangerous Situation (PDS)".

Multiple counties in Southern California were under red flag warnings from the NWS early Monday, with the service warning of yet another round of Santa Ana winds.

The potentially hazardous conditions are expected Tuesday afternoon through Wednesday in Los Angeles and Ventura counties, according to the NWS.

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.

The fire ignited in Pacific Palisades amid "a life-threatening, destructive, widespread windstorm," officials said.

The National Weather Service has issued a red flag warning for Los Angeles and parts of Ventura County through Thursday evening, meaning that conditions for wildfires will be at their highest thanks to low humidity,

Powerful Santa Ana winds are returning to the Los Angeles area this week, worrying officials as they work to contain multiple large wildfires.

As the catastrophic wildfires continue to rage in Southern California, some Los Angeles residents are not waiting around to see if their city survives. Instead, they are packing up and moving across the country to the relative safety of the Northeast.

The Auto Fire has burned nearly 61 acres in Ventura, California Monday night and was at 47% containment Tuesday afternoon.

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.
