37 million at risk for flooding from blockbuster California rainstormThe second and stronger storm of a one-two punch will blast California with torrential rain, flooding and feet of snow. CopiedFrom Southern California to the Bay Area, powerful storms caused flooding on Feb. 1. “Roughly 94% of California's population, up to 37 million people, is at risk for flooding, some of which can be life-threatening. Due to the numerous mountains and hills, even just a few inches of rain can cause significant flooding," AccuWeather Senior Director of Forecasting Operations Dan DePodwin stated. "The greatest risk of a widespread flooding disaster is expected across the canyons and hills of Southern California, especially in Ventura, Santa Barbara and Los Angeles counties,” DePodwin added.
