Overview
- Flash flood warnings stretched across Los Angeles, Ventura, Santa Barbara and San Bernardino counties as rainfall rates near 1 to 1.25 inches per hour produced widespread urban flooding and debris flows.
- Authorities issued targeted evacuation orders and warnings around recent wildfire burn scars, with deputies going door to door at about 380 high‑risk homes and rescuers aiding trapped residents in Wrightwood; Lytle Creek was under an evacuation order.
- Gov. Gavin Newsom declared a state of emergency in multiple counties to speed storm response, as local agencies opened shelters and deployed barriers and sandbags in vulnerable areas.
- Travel and infrastructure suffered major disruptions, including road closures such as portions of Interstate 5 near Burbank, downed trees and power lines, flight delays, and tens of thousands of outages as gusts topped 60–80 mph in some areas.
- Forecasts call for 4–7 inches of rain in coastal and valley areas and 6–14 inches in foothills and mountains through Friday, with feet of Sierra Nevada snow making mountain pass travel difficult or impossible.
