Extreme fire weather remains in the Southern California region as high winds have prompted a "Particularly Dangerous Situation" red flag warning,​ weather officials say.

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

Helping drive the wildfires in the US city of Los Angeles are the so-called Santa Ana winds, a weather phenomenon known to dry out "the hills and the nerves to flash point."
