LOS ANGELES:-  Los Angeles County Public Works urges residents, especially those living in or near recent burn areas, to prepare ahead of an approaching storm system expected to bring up to 1.75 inches of rain in valley areas and 2-4 inches in mountain areas between late Monday evening and Wednesday morning. A flood watch is in effect across the region, and the National Weather Service cites potential for short, high-intensity rainfall rates, thunderstorms, and an increased risk of waterspouts and tornados.

Recent burn areas, including those impacted by the January 7 wildfires, remain highly susceptible to mud and debris flows. Residents in these areas are urged to stay vigilant, monitor official weather updates, and avoid unnecessary travel during the storm—especially if they have been advised of potential mudflow risks in their neighborhoods.

LA County Public Works weather forecasters and engineers expect potentially significant flash flooding and mudflows in recent burn scar areas. Potentially vulnerable locations include the Eaton, Palisades, Hawk, Hurst, Kenneth, Sunset, Lidia, Bridge and Franklin burn areas.

“While this may be a short-duration storm, even a burst of intense rain can quickly create dangerous conditions in burn areas,” said Mark Pestrella, P.E., director of LA County Public Works. “Our crews are ready, and we urge residents to make personal safety their top priority. Avoid driving on mountain roads or in burn areas, if at all possible, and keep trash cans and vehicles off streets to allow storm runoff to travel freely.”

Storm-related issues—including fallen trees, flooded intersections, and inoperable traffic signals—can be reported through the LA County Public Works 24-hour helpline, at 1-800-675-4357.

“We are actively monitoring conditions and coordinating with emergency response agencies,” Pestrella added. “Our goal is to keep people safe and minimize storm impacts to the community.”
