California Christmas Storm 2025: Atmospheric River Triggers Flooding, Rescues, and State of Emergency

Published on December 26, 2025

As the winter sun usually glimmers over the Pacific, December 2025 has instead brought a relentless wall of water to the Golden State. A powerful atmospheric river—often called a “Pineapple Express” for its tropical origins—slammed into California on Christmas Eve and Christmas Day, transforming one of the busiest travel weeks of the year into a battle against nature.

From the flooded freeways of Los Angeles to the buried mountain roads of San Bernardino, the storm has forced millions to reconsider their holiday traditions. For many, the gift this year wasn’t under the tree, but rather the safety of their homes and the unexpected kindness of neighbors.

A State Under Siege: The Scale of the Storm

The data from the 2025 Christmas storm is staggering. Forecasters have described this as a “five-to-ten-year event,” delivering months’ worth of rain in just 48 hours. Southern California, which typically receives less than an inch of rain during this period, was battered by totals ranging from 4 to 11 inches.

• State of Emergency: Governor Gavin Newsom declared a state of emergency across six counties—including Los Angeles, Orange, Riverside, San Bernardino, San Diego, and Shasta—to mobilize the National Guard and rapid-response resources.
• The Power of Water: Over 120,000 residents across the state were plunged into darkness as wind gusts exceeding 60 mph toppled power lines and ancient trees.
• A Heavy Toll: Tragically, the storm has been linked to at least three deaths, including a 64-year-old man in San Diego crushed by a falling 75-foot tree and a sheriff’s deputy in a weather-related crash south of Sacramento.

The Burn Scar Crisis: A Fragile Landscape

The most harrowing stories come from areas still reeling from the wildfires of January 2025. In neighborhoods like Pacific Palisades and Malibu, the scorched soil acts like concrete, unable to absorb a single drop of water.

In the mountain resort town of Wrightwood, the holiday turned into a survival situation. Flash floods transformed local roads into churning rivers of mud and debris. One young family, Dillan Brown, his wife, and their 14-month-old daughter, found themselves trapped in a rental cabin with no food and a dwindling supply of diapers after rocks blocked the mountain passes. In a heartwarming display of “Christmas spirit,” neighbors organized through social media, arriving on foot with milk, vegetables, and supplies to ensure the family was safe.

Travel Upended: The “Stay Home” Mandate

For millions of Californians, the “Home for the Holidays” dream was literally washed away. The Angeles Crest Highway and State Route 138 saw significant washouts, while major freeways like the I-5 faced hours of closures due to standing water and rockslides.

“If you were planning to travel during Christmas, please reconsider,” warned NWS meteorologist Ariel Cohen. Many Angelenos took the advice to heart. The usual bustling traffic of the 405 gave way to the sound of sirens and rushing water. For those who did brave the roads, the journey was treacherous, with several water rescues performed after cars were swept into drainage tunnels or submerged in urban intersections.

The “Second Wave” and the Path to Recovery

While a brief “breather” occurred on Christmas morning, a second atmospheric river is currently moving in, threatening to drop an additional 1 to 3 inches of rain on already saturated ground. With the soil unable to hold more moisture, the risk of landslides and debris flows remains at a Level 3 (Moderate) risk through Friday night.

Staying Safe Through the New Year:

• Respect the K-Rails: If you live in a burn scar area, do not ignore evacuation orders. Debris flows can move faster than a person can run.
• Avoid Standing Water: “Turn around, don’t drown” remains the golden rule. It takes only 12 inches of rushing water to sweep away most cars.
• Check the Grid: Keep devices charged and monitor local alerts via ReadySBC.org or similar county-specific emergency portals.

Humanizing the Storm: The Resiliency of Community

Despite the evacuations and the darkness, the 2025 Christmas storm has highlighted the resilience of the California spirit. From neighbors helping elderly residents sandbag their homes to strangers sharing generators in Wrightwood, the “Pineapple Express” could not wash away the sense of community.

As we look toward the New Year, the focus remains on recovery and the stark reminder that in the face of a changing climate, preparation and neighbours are our greatest defences.
