Here's How Much Rain Just Drenched SoCal

New Year's Day Storm Unleashes Heavy Rain Across Southern California

A potent atmospheric river storm is currently drenching Southern California, marking a wet start to 2025 for the region. The system, which moved in overnight, is delivering steady and at times heavy rainfall from Santa Barbara down through Los Angeles and into Orange and San Diego counties.

Widespread Impacts and Immediate Concerns

The consistent precipitation has led to immediate concerns about flooding and debris flows, particularly in areas recently scarred by wildfires. Several canyon roads and low-lying intersections have already experienced pooling water, prompting advisories for drivers to avoid non-essential travel. The National Weather Service has issued Flood Watches for millions of residents, warning that the slow-moving nature of the storm could lead to significant rainfall totals before it pushes eastward.

Meteorologists note that this event is characterized by a deep plume of tropical moisture, contributing to the high rainfall rates. While the rain is expected to continue through much of the day, the intensity is forecast to gradually diminish by Tuesday evening. However, the saturated ground will remain a hazard even after the heaviest bands pass.

Safety Precautions and Regional Outlook

Emergency management officials are urging the public to stay informed and prepared. Key recommendations include avoiding driving through flooded roadways, securing outdoor items that could be swept away by runoff, and being aware of the potential for downed trees or power lines in areas with gusty winds accompanying the rain.

In the mountains, the storm is delivering heavy snow at higher elevations, creating difficult travel conditions over major passes. The wet weather is expected to clear out by mid-week, giving way to a period of drier and cooler conditions.

What do you think?

• Should local governments impose mandatory travel restrictions during storms of this magnitude to prevent rescues and protect first responders?


• Is the increasing frequency of these intense atmospheric river events evidence that current infrastructure can no longer handle California's "new normal" climate?


• With fire season followed immediately by flood season, are residents in wildfire zones being asked to bear an unreasonable and dangerous burden of risk?


• Does the public generally underestimate the power of moving water, or have recent years improved awareness about the dangers of driving through flooded roads?
