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.

Another round of Santa Ana winds has moved into Southern California and will spread south through San Diego County late Thursday. The additional dry air also is expected to worsen the region’s already very low humidity levels,

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

A "Particularly Dangerous Situation" (PDS) red flag fire warning is in effect in Southern California. A red flag warning means that critical fire weather conditions are either occurring now, or will shortly.

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.

Another round of Santa Ana winds is forecast to sweep into SoCal on Thursday night into Friday morning, putting most of the region under a critical fire risk, as emergency responders battle to contain quickly spreading wildfires.
