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

Dangerous Santa Ana winds are expected to return to the Los Angeles area this week, potentially fueling the growth of new and existing wildfires, according to FOX Weather.

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

After a weekend of reprieve allowing fire teams to continue making progress battling the deadly infernos burning in Los Angeles County, Southern California now faces another round of fire-fueling Santa Ana winds.

Millions of California residents were placed under a red flag warning through Thursday amid threats of further fires with looming winds in the forecast, according to multiple reports.

More than 31,000 people have been ordered to evacuate, and another 23,000 are under evacuation warnings from the path of the fire around Castaic Lake.

As wildfires continued to burn in Los Angeles, three fires broke out in San Diego County, prompting evacuation orders and warnings.

The Los Angeles region, still reeling from this month’s firestorm, is under a red-flag warning from noon Monday through Tuesday morning.

Southern California will continue to face "dangerous fire weather conditions" including strong Santa Ana winds and extremely low humidity through later this week, forecasters said Tuesday.
