Southern California is braced for "extremely critical fire conditions" caused by a new period of Santa Ana winds of up to 50 mph.

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.

After a brief break on Sunday afternoon, another prolonged round of gusty Santa Ana winds is expected to develop, forecasters say.
