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

Fire crews in Los Angeles have gotten a brief reprieve from brutal Santa Ana winds that have been fueling five wildfires. At least three are still raging at zero containment, and nearly 180,00 people are under mandatory evacuation orders,

The devastating fires that have killed at least five people and forced the evacuations of tens of thousands of residents across the Los Angeles region are driven by Santa Ana winds that blow from the deserts of interior California and Nevada out to the Pacific Ocean.

The intense and fast-moving fires that have cut a path of destruction through the suburbs of Los Angeles, killing at least two people, are being driven by the region's powerful Santa Ana winds, with gusts that in some cases surpass hurricane-strength.

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.
