San Diego, CA – What was once a possibility of rain this Christmas has now become a certainty, as a powerful storm system barrels toward Southern California, forecasters say. Authorities are warning residents to prepare for heavy rainfall, strong winds, and potential flooding in many areas.
Heavy Rainfall Expected Across the Southland
The National Weather Service (NWS) predicts 4 to 8 inches of rain across much of the region from Tuesday through Friday, with snow levels dropping to around 7,000 feet in the mountains.
KTLA weather anchor Mark Kriski described the forecast as:
“It’s going to be a messy Christmas, that’s for sure. This forecast keeps getting worse.”
Forecast charts indicate nearly a 100% chance of at least half an inch of rain across Southern California, with some areas facing a 50% chance of receiving more than 4 inches.
- Los Angeles low-end rainfall: 2.3 inches
- Los Angeles high-end rainfall: 5.1 inches
- Mountain regions: 5 to 9.5 inches
High Winds and Flood Concerns
The Weather Service has issued a High Wind Watch and flood advisories for much of Southern California. Gusts could reach 50 mph, contributing to dangerous conditions.

Forecasters also caution about mudslides, particularly in wildfire burn scar areas such as Malibu, where residents are encouraged to pick up sandbags at local libraries and take precautions against potential flooding.
Timeline of the Storm
- Tuesday: Rain begins across the region
- Tuesday Night – Wednesday: Periods of heavy downpours accompanied by strong winds
- Christmas Day through Weekend: Showers expected to continue, with persistent rainfall and gusty conditions
Officials emphasize that the storm has the potential to cause major travel disruptions, flash flooding, and hazardous driving conditions, especially on steep or burn-scarred terrain.
Safety Measures and Preparedness
Residents are advised to:
- Monitor local weather updates and alerts
- Avoid driving through flooded roads or low-lying areas
- Prepare emergency kits and ensure sandbags are ready in flood-prone locations
- Secure loose outdoor items that could be blown away by high winds
This storm is expected to be one of the most impactful weather systems of the season, making it crucial for Southern Californians to take precautions for themselves, their families, and their property.
