A powerful Pacific storm is bringing heavy rain, strong winds, and potential flooding to Los Angeles and Southern California. Here’s the latest forecast, rainfall totals, and safety alerts for the region.
Southern California Weather Alert: Heavy Rain and Windstorm Slam Los Angeles
A strong Pacific storm system continued pushing across Southern California on Sunday, delivering intense rain, powerful winds, and localized flooding across Los Angeles County and nearby regions. Forecasters warn that conditions will remain unstable through Monday morning, especially in mountain and foothill communities.
Up to an Inch of Rain Expected for Los Angeles Through Sunday Night
According to the National Weather Service, most areas across the Los Angeles Basin are expected to receive around 1 inch of rainfall, with some foothill regions experiencing higher totals. The San Gabriel Mountains and surrounding communities are facing the highest risk of mudslides and debris flows due to the combination of saturated soil and ongoing rain.
Strong Wind Gusts Could Cause Damage and Power Outages
A wind advisory remains in effect for parts of Southern California, with gusts reaching 35–45 mph in several areas. These winds may lead to:
- Fallen tree branches
- Difficult driving conditions
- Possible localized power outages
- Hazardous conditions for high-profile vehicles
Weather officials urge residents to secure outdoor items and use caution when driving, especially along coastal highways and canyon roads.
Flood Watch in Effect for Low-Lying Areas
The heaviest rainfall is expected during the late afternoon and evening hours, increasing the risk of urban flooding and road ponding in low-lying areas such as:
- Downtown Los Angeles
- San Fernando Valley
- South Bay communities
- San Gabriel Valley
Drivers are advised to avoid flooded roadways and remain alert for sudden changes in weather conditions.
Mountain Areas Face Elevated Mudslide and Debris Flow Threat
The San Gabriel Mountains and other elevated regions may experience dangerous runoff, especially near burn scars from recent wildfires. Officials warn that even moderate rainfall could trigger debris flows that block roads or endanger nearby homes.
Residents in these high-risk zones should monitor emergency alerts and be prepared to evacuate if conditions worsen.
More Rain Coming Monday Before Conditions Improve
While the storm is expected to weaken Monday afternoon, forecasters say scattered showers may continue through early Tuesday. Cooler temperatures and lingering moisture could also lead to slick roads during the morning commute.
What Residents Should Do
- Check local weather alerts frequently
- Avoid canyon and mountain roads during heavy rain
- Keep emergency kits ready
- Stay away from fast-moving flood channels
- Allow extra commute time
