Overview
- The National Weather Service issued widespread flash flood warnings for Los Angeles, Ventura and Santa Barbara counties, with rainfall rates topping 1 inch per hour and a rare High Risk designation for excessive rain.
- Evacuation orders and warnings target neighborhoods near recent burn scars such as the Palisades and Eaton fires as deputies contacted roughly 380 high‑risk homes, and Wrightwood faced an evacuation warning with some rescues reported.
- Power trackers reported roughly 100,000 to 140,000 customers without electricity as winds up to 60–80 mph toppled trees and power lines, and a brief tornado warning was issued for part of east‑central Los Angeles County.
- Forecasts call for 4–7 inches of rain in coastal and valley areas and 6–14 inches in foothills and mountains, with feet of Sierra Nevada snow making mountain travel difficult or impossible.
- Officials urged people to reconsider holiday travel as a second pulse of atmospheric river energy is expected to prolong heavy rain, strong winds and mountain snow through Friday, and Governor Gavin Newsom declared a state of emergency in multiple counties.
