A powerful winter storm has drenched Southern California, leading to severe flooding risks just before Christmas, with another storm expected to bring more rain and potential thunderstorms. Areas affected by previous wildfires are particularly vulnerable, prompting evacuation orders and rescue operations in places like Wrightwood and Lytle Creek. Residents have rallied to support each other, delivering essential supplies to those stranded. The storms, fueled by atmospheric rivers, are projected to deliver significantly more rainfall than average for this time of year, raising concerns over infrastructure and safety. State officials have declared a state of emergency in six counties and are mobilizing resources for storm response.
