Firefighters held the line against two massive wildfires that have ravaged parts of Los Angeles for the past week, even as desert winds and a parched landscape presented extremely hazardous conditions.

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

Firefighters are getting a much needed break today as Santa Ana winds developed later and weaker than originally expected, but forecasters warn strong gusts are still possible into Wednesday. The National Weather Service had originally issued a “Particularly Dangerous Situation” red flag warning that was expected to take effect at 4 a.
