California entered the Christmas week under the strain of another powerful winter storm system, prompting Governor Gavin Newsom to proclaim a state of emergency across a wide swath of the state. The declaration, issued Wednesday, covers Los Angeles, Orange, Riverside, and San Bernardino counties, with additional proclamations extended to San Diego and Shasta counties as heavy rain, strong winds, and the threat of dangerous secondary hazards battered communities already on edge after recent wildfires.
The emergency order comes as the latest in a series of winter storms to hit California this season, underscoring the growing volatility of the state’s weather patterns and the heightened risks faced by communities living near burn scar areas. With saturated soil, steep terrain, and limited vegetation to stabilize hillsides, officials warned that even moderate rainfall could trigger mudslides, debris flows, and flash flooding.
“California is acting early and decisively to do all we can to get ahead of dangerous winter storms,” Governor Newsom said in a statement accompanying the proclamation. “The state has pre-positioned resources, activated emergency authorities, and we are working closely with local partners to protect communities and keep Californians safe.”
Storm Impacts Across Southern California
The storm system sweeping across Southern California brought widespread rainfall, gusty winds, and unstable atmospheric conditions. According to the National Weather Service (NWS), some parts of Los Angeles County were forecast to experience strong thunderstorms, with wind gusts reaching up to 50 miles per hour. These winds are strong enough to down trees, damage power lines, and create hazardous travel conditions, particularly for high-profile vehicles.
The NWS issued a Special Weather Statement through midday, warning residents that thunderstorms could produce brief but intense bursts of wind and heavy rain. Doppler radar tracked a line of strong storms stretching from roughly six miles north of Sunland through Alhambra and down toward Los Alamitos, illustrating the broad reach of the system as it pushed west to east across the region.
Meteorologists also noted the possibility—though considered unlikely—of a brief “spin-up” tornado. These short-lived tornadoes can form quickly within strong thunderstorms, often with little warning, and while rare in Southern California, they highlight the unusual intensity of the storm environment.
Burn Scars and the Threat of Debris Flows
One of the most serious concerns tied to the storm is the risk faced by communities located below recent wildfire burn scars. Wildfires fundamentally alter the landscape, burning away vegetation that would normally absorb rainfall and anchor soil in place. In some cases, intense heat can also create a water-repellent layer in the soil, causing rain to run off rapidly rather than soaking in.
When heavy rain falls on these areas, it can trigger fast-moving debris flows—mixtures of mud, rocks, ash, and vegetation—that surge downhill with little warning. These flows can damage or destroy homes, block roads, and pose a deadly risk to anyone in their path.
As a result, several communities near burn scar zones were placed under evacuation warnings. These warnings, while not mandatory orders, urge residents to be prepared to leave quickly if conditions worsen. Emergency officials emphasized that debris flows can occur suddenly, even if rainfall does not seem extreme, and that nighttime storms increase the danger because residents may be caught off guard while asleep.
Emergency Response and State Preparedness
Governor Newsom’s emergency proclamation activates a range of state authorities and resources designed to support local governments during disasters. These measures can include deploying California National Guard units, pre-positioning swift-water rescue teams, clearing debris basins, and streamlining access to emergency funding and mutual aid.
State agencies, including Cal OES (the Governor’s Office of Emergency Services), coordinated closely with county and city officials to monitor conditions in real time. Transportation crews were placed on standby to respond to road closures, while utility companies prepared for potential power outages caused by high winds or falling trees.
In past storms, pre-positioning resources has proven critical in reducing response times and limiting damage. By staging equipment and personnel ahead of the storm, authorities aim to act quickly if flooding, landslides, or infrastructure failures occur.
Impacts on Daily Life
For residents across the affected counties, the storm disrupted daily routines and holiday travel plans. Heavy rain slowed traffic on major freeways, increased the risk of hydroplaning, and led to localized street flooding. In mountain and desert areas of San Bernardino and Riverside counties, strong winds compounded the danger, creating hazardous driving conditions and raising the risk of falling debris.
Schools, businesses, and holiday events monitored the situation closely, with some opting to close early or cancel activities out of caution. Emergency officials urged residents to avoid unnecessary travel during peak storm periods and to stay informed through official alerts and weather updates.
Coastal areas were not immune to impacts either. Elevated surf and gusty onshore winds raised concerns about coastal erosion and minor flooding in low-lying areas, particularly during high tides.
The Broader Context: California’s Changing Climate
This latest storm fits into a broader pattern of increasingly extreme weather in California. In recent years, the state has swung between prolonged droughts and periods of intense rainfall, a phenomenon scientists often describe as “weather whiplash.” Warmer temperatures can allow the atmosphere to hold more moisture, leading to heavier downpours when storms do arrive.
At the same time, climate change has contributed to longer and more destructive wildfire seasons, leaving behind extensive burn scars that heighten flood and mudslide risks during winter storms. This combination has forced emergency planners to rethink how communities prepare for and respond to natural disasters.
Governor Newsom and other state leaders have repeatedly pointed to these challenges as evidence of the need for long-term investments in climate resilience, including improved forest management, upgraded stormwater infrastructure, and better early warning systems for floods and debris flows.
Lessons From Past Storms
California’s history offers sobering reminders of what can happen when heavy rain meets vulnerable terrain. In previous years, intense storms have triggered deadly debris flows, most notably in Montecito in 2018, where mudslides following a wildfire claimed lives and destroyed hundreds of homes. While conditions vary from storm to storm, those events continue to shape how officials and residents respond to similar threats today.
As a result, evacuation warnings and emergency declarations are often issued earlier and more broadly than in the past. Officials stress that these actions are precautionary, aimed at preventing loss of life rather than reacting after disaster strikes.
What Residents Are Urged to Do
Emergency authorities encouraged residents in affected areas to take common-sense precautions. These include avoiding flooded roadways, securing outdoor objects that could become airborne in high winds, and staying away from creeks, rivers, and steep hillsides during and after heavy rain.
Those living near burn scars were urged to have evacuation plans ready, including go-bags with essential items, medications, and important documents. Officials also reminded the public to heed evacuation warnings and orders promptly, emphasizing that waiting too long can be dangerous if roads become blocked by debris or floodwaters.
Looking Ahead
As the storm system continues to move through California, forecasters are closely monitoring its progression and potential impacts. While rainfall totals and wind speeds may vary by location, the overall message from authorities remains consistent: stay alert, stay informed, and take warnings seriously.
Governor Newsom’s state of emergency declaration reflects both the immediate threat posed by the storm and the broader reality that extreme weather is becoming a more frequent challenge for California. For communities across Los Angeles, Orange, Riverside, San Bernardino, San Diego, and Shasta counties, the coming days will test preparedness efforts and underscore the importance of coordination between state, local, and federal partners.
While the full extent of the storm’s impact may not be known until it passes, officials hope that early action, clear communication, and public cooperation will help minimize damage and keep Californians safe during yet another demanding winter weather event.
