Another strong storm moved into Southern California on Thursday, following earlier weather systems that brought heavy rain and gusty winds to the region.
Forecasters warned that more rain could worsen flooding and trigger mudslides.
The risk remains high in areas burned by wildfires in January. Hillsides stripped of vegetation absorb less water, making debris flows more likely. Officials urged residents in vulnerable zones to stay alert as rain fell on already soaked ground.
In Wrightwood, a mountain town northeast of Los Angeles, flooding hit as firefighters issued evacuation warnings on Christmas Eve.
