Southern California Storm System: Evacuation Warnings, Floods, and Snowfall Alerts
Southern California is facing a dangerous storm system that is bringing heavy rain, flash floods, and the potential for significant snowfall in the Sierra Nevada. Evacuation warnings have been issued for neighborhoods affected by recent wildfires, with officials urging residents to take precautions and be prepared for emergency warnings. The storm is expected to bring 1 to 3 inches of rain in coastal areas and up to 8 feet of snow in the mountains, creating hazardous conditions.
The National Weather Service has issued flood watches and warnings for Los Angeles County, with the possibility of rock and mudslides near steep terrain. Mayor Karen Bass has emphasized the importance of following official guidance and staying informed during this significant weather event. The rapid rainfall rates could overwhelm storm drains and lead to flooding in some areas, especially in burn scar zones.
The storm is impacting the Transverse Ranges, causing heavier rain in mountain areas due to orographic lift. Areas recently affected by wildfires are at a higher risk of debris flows, as burned soil becomes water-repellant and can trigger fast-moving landslides. Meanwhile, the Sierra Nevada is preparing for heavy snowfall, with popular ski destinations expecting over 60 inches of fresh powder and travel disruptions expected on Interstate 80.
Travelers at San Francisco International Airport are experiencing delays due to low ceilings, rain, and gusty winds. A wind advisory is in effect across Southern California, with gusts reaching up to 70 mph in some areas. A second storm is forecasted to bring colder temperatures, additional rain, and mountain snow, potentially causing travel hazards on mountain roads. Residents are advised to stay informed and take necessary precautions during this ongoing weather event.
