Los Angeles, CA – A wet and potentially hazardous week is ahead for much of Southern California, with the heaviest rain and storm impacts expected Monday.
According to the National Weather Service Los Angeles/Oxnard, widespread rain will develop late Sunday before intensifying Monday, when the highest rainfall rates and a 20–40% chance of thunderstorms are forecast. Forecasters warn that localized flash flooding, rockslides, and mudslides will be possible, especially in burn scar areas and mountain communities.
Rain totals through the week could reach 2 to 4 inches across coastal and valley areas, including Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties. Higher elevations in the mountains and foothills may see 4 to 8 inches of rain by Friday, significantly increasing the risk of debris flows and roadway hazards.
The most impactful conditions are expected during Monday’s morning and evening commutes, when downpours could reduce visibility and create ponding on major routes including U.S. 101, Interstate 5, and Highway 154. Gusty winds may also develop with thunderstorms.
Residents are urged to avoid flooded roads, allow extra travel time, and remain alert for rapidly changing weather. Drivers encountering heavy rain are advised to slow down and, if necessary, pull over safely until conditions improve.
The storm system is expected to taper midweek, though additional showers remain possible through Thursday.
