Los Angeles, California – A long-duration storm could bring flooding, mountain snow, and coastal impacts beginning Sunday night across Los Angeles County.
According to the National Weather Service in Los Angeles, moderate to heavy rain is expected to develop late Sunday, Feb. 15, and continue into Tuesday, Feb. 17, with the most concentrated rainfall projected between 3 a.m. and 9 p.m. Monday.
Forecasters say there is high confidence in at least moderate rainfall and mountain snow, accompanied by gusty winds. Thunderstorms are possible Monday into Tuesday, with brief heavy downpours and isolated damaging wind gusts.
Flooding concerns include roadway flooding, debris flows, mudslides, and rockslides, particularly in and below recent burn scar areas. Officials warn that elevated river and stream flows may increase through Monday night.
Snow levels are expected to lower Tuesday through Thursday, potentially impacting higher elevations including the Interstate 5 Tejon Pass corridor. Road delays or closures are possible in mountain areas.
Winds throughout the week may down trees and power lines, creating isolated outages and airport delays, including at LAX. Coastal impacts are also expected, with building surf and potential beach flooding Tuesday through Wednesday along Pacific Coast Highway.
The Los Angeles County Sheriff’s Department urges residents to review evacuation terminology, including the difference between an Evacuation Warning and an Evacuation Order, and to register for Alert LA County notifications.
Commuters along U.S. 101, Interstate 405, Interstate 5, and Pacific Coast Highway should prepare for hazardous travel conditions.
Residents are encouraged to secure property, clear drains, and monitor official updates as the storm approaches.
