Torrential rains and strong winds in Southern California over the past few days have caused widespread flooding, multiple evacuation warnings, and at least three casualties. California’s Governor Gavin Newsom declared a state of emergency in six counties, including Los Angeles, to allow state assistance. The extreme weather has led to power outages across the state, with Monterey being the most affected. Multiple roads were closed due to debris and inundation, including the Angeles Crest Highway. The storm is forecast to continue until 27 December, potentially exacerbating flooding and landslide risk across the affected regions.
