Los Angeles, March 11, 2025 — Angelenos, it’s time to brace yourselves! A powerful storm system is set to sweep across Southern California, bringing heavy rainfall, strong winds, and even snow in the mountains. While the city has been basking in mild spring-like weather, that’s about to change dramatically.
What to Expect: The Storm Breakdown
The National Weather Service has issued a Winter Storm Watch for the Los Angeles County Mountains, effective from Wednesday afternoon through Friday morning. This storm is part of an atmospheric river event, meaning it’s packing a significant amount of moisture that could lead to flooding, travel disruptions, and power outages across the region.
Heavy Rainfall and Flooding Risks
- Los Angeles and surrounding areas are expected to receive 1 to 3 inches of rain, with heavier amounts in foothill and mountain regions.
- Low-lying neighborhoods, underpasses, and areas with poor drainage could see localized flash flooding.
- Burn scar areas from past wildfires, such as in the San Gabriel Mountains, are at high risk for mudslides and debris flows.
Strong Winds Could Knock Out Power
- Winds will pick up ahead of the storm, with gusts reaching 40 to 50 mph in coastal and valley areas.
- Higher elevations could see gusts exceeding 60 mph, raising concerns about downed power lines and tree damage.
- Possible power outages are expected in some areas, so have flashlights, batteries, and emergency supplies ready.
Mountain Snow and Dangerous Travel Conditions
- If you’re heading to the mountains, be prepared for a winter wonderland—but also hazardous travel.
- Elevations above 3,000 feet could see up to a foot of snowfall, with higher amounts possible at peaks.
- The Grapevine on Interstate 5 may experience icy roads and snowfall, potentially leading to closures or dangerous driving conditions.
How to Stay Safe and Prepared
- Avoid unnecessary travel – If you don’t need to be on the roads during the peak of the storm, stay home. Flooded streets and slick highways will create hazardous driving conditions.
- Prepare for potential power outages – Charge your phones and devices, stock up on candles, and have emergency supplies like food and water handy.
- Check on vulnerable neighbors – Elderly individuals and those with mobility issues may need extra assistance during extreme weather.
- Stay informed – Monitor official weather sources, such as the National Weather Service and local news stations, for the latest updates and emergency alerts.
What’s Next?
This storm is part of a larger pattern bringing multiple rounds of wet and cool conditions throughout March. While rain is desperately needed after long dry spells, too much at once can create dangerous conditions. Expect another system to arrive early next week, bringing additional rain and possible thunderstorms.
Los Angeles, get ready. This storm is not one to take lightly, but with preparation and caution, we can ride it out safely. Stay dry, stay safe, and take care of each other!
