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

Strong Santa Ana winds are hitting fire-ravaged Los Angeles on Friday morning, but the winds will relax later in the day and the red flag warning will end Friday night.

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.

High-speed winds this week have the potential to knock over semitrucks and cause other hazardous driving situations. Here's what to know.

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.

The potentially hazardous conditions are expected Tuesday afternoon through Wednesday in Los Angeles and Ventura counties, according to the NWS.

The National Weather Service has issued a Red Flag waning for a wide swath of Southern California as Santa Ana winds are expected to bring dangerous fire weather to the region later this week.

Although the strongest wind gusts have passed through the Southern California region, another "traditional Santa Ana wind event" will move in Thursday night.
