At the direction of Governor Gavin Newsom, the Governor’s Office of Emergency Services (Cal OES) today approved the preposition of mud and debris flow resources in Los Angeles, Ventura, Orange and Santa Barbara counties starting Monday evening, October 13, 2025.
Swiftwater, mud and debris flow crews and equipment are being deployed ahead of a significant storm system expected to bring strong winds, thunderstorms, heavy rain, flash flooding, and mountain snow. In Southern California, rainfall totals of 2-4 inches are expected across coastal mountains and foothill areas.
These efforts ensure that resources are ready to respond quickly, minimizing the potential impacts. The state is prepositioning over 200 personnel and dozens of pieces of equipment including fire engines, bulldozers, hand crews, helicopters, front loaders, a swiftwater rescue team and an urban search and rescue (US&R) company.
In addition to impacts to Southern California, Monday’s storm is expected to affect the Central Valley, the Sierra Nevada and the Bay Area, with some areas seeing high rainfall rates, thunderstorms, and more than 3 inches of rain.
Local fire agencies identify when conditions in communities may require additional resources and submit requests to the state for support. The staging locations and response assignments are coordinated by local officials. The California Fire and Rescue Mutual Aid System remains available for local fire officials to request additional resources during an incident if necessary.
Residents are urged to stay vigilant during this heightened precipitation and extreme weather period. Californians are reminded to:
- Sign up for local emergency alerts to stay informed about changing conditions.
- Review your family emergency plan and check on your neighbors.
- Be prepared to evacuate, if needed.
