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.

With fire crews slowly making progress against a series of devastating Los Angeles wildfires that have claimed at least 10 lives, Santa Ana winds will buffet the region for one more day Friday.
