Heavy rain from an atmospheric river knocked out electricity for thousands as officials warned of flooding and debris flows during the holiday.
By Samuel Lopez | USA Herald – The lights went out for thousands of Southern Californians as Christmas Eve began under pounding rain and high winds. What should have been a calm holiday morning quickly turned uncertain for families waking up without power.
Utility crews scrambled as outages spread across neighborhoods already on edge from recent wildfires. With saturated hillsides and swollen creeks, officials warned that the storm carried risks well beyond temporary inconvenience.
Data from utility outage maps and emergency alerts shows a region confronting the compounded effects of extreme weather, aging infrastructure, and seasonal vulnerability—right as millions prepared for Christmas.
Power outages were reported across Los Angeles County on the morning of Dec. 24 as a strong atmospheric river system moved through Southern California. According to publicly available outage data from Southern California Edison, at least 27 separate outages were active in the county around 8:30 a.m., affecting just over 8,000 customers.
Several outages were explicitly labeled as caused by “storm condition,” while others were attributed to downed trees and equipment issues—factors commonly linked to high winds and saturated soil. Utility estimates indicated that many of the outages were expected to be restored throughout Christmas Eve, ranging from morning through evening hours, though restoration timelines can shift as weather conditions evolve.
The outages coincided with warnings from local officials about widespread flooding risks. In areas recently scarred by wildfires, evacuation warnings were scheduled to take effect on Dec. 23 due to the heightened threat of debris and mud flows. Burn scars are especially vulnerable during heavy rain, as vegetation that once stabilized slopes has been lost, increasing the likelihood of fast-moving runoff.
An outage map published by the Los Angeles Department of Water and Power showed additional service disruptions across the county, including in Sherman Oaks, near Van Nuys, and in the Woodland Hills area. As of publication, the department had not publicly confirmed whether those outages were directly caused by weather, though the timing aligns with peak storm impacts.
The disruptions were not confined to Los Angeles County. Outage data from Southern California Edison showed numerous service interruptions across the region, including parts of Orange, Riverside, San Bernardino, Santa Barbara, and Ventura County. The broad geographic footprint underscores the scale of the storm system impacting Southern California during one of the busiest travel and family-gathering periods of the year.
From an infrastructure and emergency-planning perspective, the timing matters. Holiday storms strain utility response capacity as staffing levels fluctuate and travel conditions complicate repairs. When outages coincide with flood warnings and evacuation notices, they also raise safety concerns for medically vulnerable residents who rely on powered medical devices or heating systems.
This storm fits a broader pattern California has experienced in recent years—short bursts of intense precipitation driven by atmospheric rivers that deliver enormous volumes of water in compressed timeframes. While such systems are essential to replenishing reservoirs, they also test drainage systems, hillsides, and power infrastructure not designed for prolonged saturation and wind stress.
As Christmas Eve progressed, utilities continued restoration efforts while emergency officials urged residents to remain alert, avoid flooded roadways, and heed evacuation guidance where issued. For many households, the day became less about celebration and more about preparedness—keeping phones charged, monitoring alerts, and waiting for the power to return.
The events unfolding across Southern California serve as a reminder that extreme weather no longer respects the calendar. Even on Christmas Eve, infrastructure resilience and public safety planning remain critical as communities adapt to increasingly volatile storm patterns.
