California’s Christmas turned into a nightmare as a powerful storm, fueled by atmospheric rivers, swept across the state, bringing widespread flooding, mudslides, and power outages. The storm has claimed at least three lives, including a 64-year-old man in San Diego crushed by a falling tree and a sheriff’s deputy in a weather-related crash south of Sacramento.
The affected areas include Southern California’s Los Angeles, Orange, Riverside, San Bernardino, and San Diego counties, as well as Northern California’s Shasta County and the Sierra Nevada mountains. Over 140,000 customers are without power, and major highways like Interstate 5 are closed due to flooding and rockslides.
Flooding Impact
The storm’s impact is severe, with flash flooding and mudslide risks, especially in areas scorched by recent wildfires. Up to 8 feet of snow is expected in the Sierra Nevada mountains, making travel conditions treacherous.

Governor Gavin Newsom declared a state of emergency in six counties, mobilizing the California National Guard to assist with rescue efforts. Evacuation orders have been issued for hundreds of homes in high-risk areas, and residents are advised to stay indoors.
The storm, known as the “Pineapple Express,” is expected to bring months’ worth of rain in just a few days, with some areas receiving up to 11 inches of rain. The National Weather Service has issued flood watches, high wind warnings, and evacuation orders for high-risk areas.
Residents are urged to reconsider their travel plans, as roads are becoming impassable, and mudslides may block highways. The storm’s impact is expected to peak on Christmas Eve, with heavy rain continuing through Christmas Day.
Emergency services are on high alert, with over 380 properties identified as requiring evacuation. Temporary shelters have been set up for those affected, and the California National Guard is on standby to assist with rescue operations.
The storm’s intensity is unprecedented, with downtown Los Angeles receiving 2.53 inches of rain on Wednesday, exceeding the city’s entire December historical average rainfall. The heaviest rain fell in the mountains northwest of the city, with 8-12 inches reported.
The National Weather Service warns of a “broad plume of moisture” producing heavy rain in California, with numerous flash flooding events possible. Streams may flood, potentially affecting larger rivers, and debris flows are likely in or near recently burned areas.
Residents are advised to stay safe by avoiding travel through flooded areas and following local evacuation orders. If you must drive, ensure your vehicle is prepared for the storm, and pack emergency supplies like water, snacks, a flashlight, and blankets.
The storm has disrupted holiday plans, with millions of people across California affected. Airports, including Los Angeles International and San Francisco International, are experiencing significant delays and cancellations.
The California Department of Transportation is working to clear roads and restore traffic flow. Residents are urged to stay informed through official channels and follow evacuation guidance.
The storm’s impact is expected to continue through the week, with another atmospheric river moving in, threatening to drop additional rain on already saturated ground. The risk of landslides and debris flows remains high.
