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.

The recent wildfires in Los Angeles were intensified by strong Santa Ana winds, which are a unique weather pattern in Southern California. These winds are caused by the topography of Southern California and the circulation of a strong high-pressure system over the Rocky Mountains.
