California Braces for Deluge: Massive Storm Threatens Flooding and Chaos

Southern California is bracing for heavy rain and the threat of flooding as the region's first El Niño-influenced storm approaches. The storm, fueled by an atmospheric river of moisture, is expected to be the biggest rainstorm since Hurricane Hilary in August. Flood alerts are in effect for approximately 22 million people, including the Los Angeles and San Diego metro areas. The heaviest rain is expected on Thursday and Friday, with the possibility of mudslides and power outages. Snow is expected in the higher elevations of the Sierra Nevada. Motorists are advised to exercise caution and allow extra travel time due to wet roads and potential ponding.
