Overview
- Los Angeles ordered evacuations and issued warnings for hundreds of households, with reports ranging from more than 100 to about 380 addresses.
- The National Weather Service put parts of Southern California on its highest flood alert and warned the storm could drop over 25–30 centimeters of rain with damaging winds.
- Early effects included downed trees, closed roads and thousands without power, and a brief tornado warning for Los Angeles that was later canceled.
- Pacific Palisades and Malibu face elevated risk of landslides and mudflows because slopes scorched by recent wildfires are highly unstable in heavy rain.
- California pre-positioned millions of sandbags, opened emergency shelters and coordinated potential National Guard support as the system continues through the holiday period.
