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.

Red Flag Warnings remain in effect through Friday evening for much of Los Angeles and Ventura Counties, the National Weather Service said.

Fresh off destructive wind and firestorms, the forecast remains daunting for Southern California with additional damaging Santa Ana wind threats and critical fire weather danger continuing at times over the next several days.
