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

A new wildfire that erupted in northern Los Angeles County rapidly consumed over 10,000 acres as authorities warned of an "immediate threat to life."

Firefighters in Southern California are once again battling a wildfire, this time in Castaic in Los Angeles County, north of Los Angeles itself. Evacuation orders have been issued for the surrounding areas.

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.

"A strong Santa Ana Wind event is expected to develop Monday and last through at least Tuesday," the National Weather Service said.

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

With the strongest gusts expected on Tuesday, extreme fire condition threats will prevail until midweek, L.A.-area fire chiefs say.

As winds across the Southern California area are calmer than their peak and firefighters are making progress, the threat to the fire-weary region remains with Santa Ana winds expected to continue in the coming days.

According to Azusa police, a man who has admitted to setting a fire at a park has been arrested as the investigation continues.
