Thu Feb 13 06:50:00 UTC 2025: ## Southern California Braces for Debris Flows as Strong Storm Approaches

**Los Angeles, CA** – Southern California is bracing for a major storm expected to bring heavy rain and a high risk of debris flows to areas scarred by recent wildfires. Evacuation warnings are in effect for several burn zones across Los Angeles County, starting Thursday morning and lasting through Friday afternoon, when the heaviest rainfall is anticipated.

The Los Angeles Fire Department issued warnings for high-risk areas including parts of the Pacific Palisades (Getty Villa, Highlands, Bienveneda), Topanga, Malibu, and areas near the Eaton, Sunset, Hurst, and Kenneth fire burn zones. The Los Angeles Police Department will be conducting door-to-door visits in the most vulnerable areas to issue specific evacuation orders. Malibu schools will be closed on Thursday due to road closures and weather concerns.

In preparation, crews have cleared 154 debris basins and installed thousands of sandbags and other preventative measures. Authorities are also employing roadways as sediment traps in some areas due to the significant amount of ash and rubble. Los Angeles County Public Works Director Mark Pestrella urged residents living near burned slopes to contact the agency with concerns.

While last week’s storms caused minimal damage, they filled a debris basin at the Eaton wash dam, highlighting the potential for significant debris flows. Officials emphasize that debris basins have been prepared for the anticipated rainfall; however, the risk of heavy mudflows, potentially reaching speeds of 35 mph, remains high. Meteorologist Ryan Kittell warns that rainfall intensity, not just total accumulation, is the critical factor, with the highest risk predicted for Thursday afternoon and evening.

Flood watches are in effect for multiple counties, including Los Angeles, Ventura, Santa Barbara, and San Luis Obispo. The storm is expected to impact the entire state, from the Bay Area to San Diego, with heavy snow anticipated in the Sierra Nevada. While officials state they have taken steps to mitigate the risk of flooding following criticism of prior storm preparedness, they urge residents to remain vigilant, heed evacuation warnings, and sign up for emergency alerts. The storm is expected to pass by the weekend, with warmer, drier weather forecast for the following week.
