Los Angeles, CA — A series of storm systems is expected to impact Los Angeles and much of Southern California during the busy holiday week, bringing periods of rain, gusty winds, and potential travel disruptions.
According to the National Weather Service in Los Angeles/Oxnard, the active weather pattern will begin to intensify Tuesday night, December 23, with impacts continuing through Thursday, December 25, and lingering rain chances into Friday, December 26.
Forecasters say rain chances will steadily increase across Los Angeles County, as well as Ventura, Santa Barbara, and San Luis Obispo counties, with the highest likelihood of widespread precipitation from Tuesday night through Thursday. During that window, residents should plan for road and airport delays and consider adjusting holiday travel plans.
Rainfall totals will vary depending on the storm track. In the most likely scenario, coastal and valley areas could see 2 to 4 inches of rain, while mountain areas may receive 4 to 8 inches. There is also a 40 percent chance of heavier rainfall, which could push totals to 4 to 8 inches in lower elevations and 8 to 15 inches in the mountains.
Peak rainfall rates could reach 0.3 to 0.8 inches per hour, with a lower-probability scenario producing rates of 0.5 to 1.0 inch per hour, increasing the risk of urban flooding, debris flows near burn scars, and rapidly rising creeks and rivers.
Strong winds are also possible Tuesday through Wednesday, with the potential for downed trees and scattered power outages. The National Weather Service urges residents to stay away from tall trees, secure loose outdoor items, and avoid the ocean during hazardous conditions.
Snow levels are expected to remain above 7,000 feet through December 24, lowering to 5,000–6,000 feet by Wednesday, which could impact mountain travel.
Residents are encouraged to monitor forecasts closely at weather.gov/lox as timing and intensity details continue to be refined.
