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

Santa Ana winds are caused by strong high pressure over the Great Basin region of the West creating a pressure gradient that amps up winds through the mountains, foothills and sometimes valleys of Southern California. In this case, the winds are getting a major boost from a strong upper-level low pushing southward across the state.

Wildfires in Los Angeles have resulted in 10 deaths and extensive property damage. The Palisades and Eaton fires are among the most destructive, exacerbated by climate change and severe drought conditions.
