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.

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.

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

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

Meteorologists said there was a chance the winds would be as severe as those that fueled the Palisades and Eaton fires, but that different locations would likely be affected.

Gusts of up to 70 mph are possible along the coast and valleys, and in the mountains, up to 100 mph, the National Weather Service said. Parts of L.A. County, and most of Ventura County, are at highest risk.
