A severe winter storm has slammed Southern California, bringing with it heavy rainfall that has triggered evacuation orders in the Los Angeles area. The storm, described as “life-threatening,” is expected to persist for several days, with nearly 42 million residents under flood watches. The National Weather Service (NWS) has noted that the heaviest rainfall is currently affecting the L.A. Basin.
As of December 24, 2023, evacuation orders have been issued in San Bernardino County due to flash floods and mudslides. Fire crews have been actively assisting residents in evacuating their homes. The NWS highlighted the ongoing “widespread flash flooding,” with rainfall rates reaching between 0.5 to 1 inch per hour.
Flooding and Hazards Continue Through Christmas
The NWS has issued a “rare High Risk of Excessive Rainfall” warning that remains in effect through Christmas Day. This alert includes the metropolitan area of Los Angeles, with the NWS describing the current conditions as “life-threatening atmospheric river conditions.” Residents are advised to remain vigilant as the storm may lead to significant flooding, particularly in urban areas.
In addition to flash flooding, the NWS warns of potential rock and mudslides across Southern California through Thursday. The combination of strong winds and saturated soils is also likely to cause widespread power outages and damage to trees. Areas adjacent to Southern California, including parts of Northern and Central California and Southern Nevada, are also expected to experience scattered instances of flash flooding.
Travel in the Sierra Nevada mountains is expected to be severely affected due to significant snowfall, with totals likely reaching several feet. These conditions are anticipated to make travel over mountain passes impossible throughout the week.
Impact on Communities and Infrastructure
The storm’s impact is evident in various communities across the region. Photos captured during the storm show flooded streets, including one near the Meta Campus in Menlo Park, California. In Ventura, play areas at the Ventura Beach RV Resort have been placed under evacuation orders as a precaution. This site experienced severe flooding in early 2023, prompting renewed concerns among local residents.
The NWS has emphasized the importance of heeding evacuation orders and staying updated on weather alerts. As the storm continues to develop, officials are closely monitoring conditions and responding to emergencies as they arise.
This situation remains fluid, and updates will be provided as more information becomes available. Residents are encouraged to prepare for ongoing challenging weather conditions and to prioritize safety during this severe winter storm.
