Southern California is bracing for an "unprecedented" third Particularly Dangerous Situation warning in a month, as extreme Santa Ana winds increase fire danger.

Windy and dry conditions have returned to Southern California, raising the risk of new wildfires sparking as firefighters continue to battle two major blazes in the Los Angeles area that started in similar weather nearly two weeks ago.

Meteorologists said there was a chance the winds would be as severe as those that fueled the Palisades and Eaton fires, but that different locations would likely be affected.
