Millions of Californians face a catastrophic flood risk as an atmospheric river brings torrential rainfall to Southern California, threatening life-threatening floods in areas near recent burn scars. Los Angeles County officials have issued evacuation orders for thousands of homes, citing the high risk of mudslides and property damage.
The National Oceanic and Atmospheric Administration (NOAA) describes an atmospheric river as a "long, narrow region in the atmosphere that transports most of the water vapor outside of the tropics." These storms are notorious for heavy snow, heavy rain, and strong winds, often hitting the West Coast during the winter months. While they can bring much-needed snow to supplement reservoirs, they also pose deadly risks of flooding, mudslides, and widespread power outages.
Residents in areas with recent burn scars are particularly at risk due to the altered landscape, which struggles to absorb water after wildfires. This can lead to rapid runoff, exacerbating flash flooding and mudslides downstream. The National Weather Service (NWS) has warned that excessive rainfall is the primary concern, with widespread flooding and debris flows likely across vulnerable burn scar areas of Santa Barbara, Ventura, and Los Angeles Counties.
Evacuation orders are in place for properties deemed at higher risk due to their proximity to recent wildfires. Law enforcement personnel are conducting door-to-door contact to notify affected residents and urge them to follow all instructions from emergency responders throughout the duration of the event.
As millions of Californians prepare for the storm, officials are urging residents to remain storm-aware and heed all advice from local authorities. The NWS flood watch remains in effect through Saturday evening, with evacuation orders set to expire at 8 am on Sunday.
