December 26, 2025

The latest round of precipitation in California is causing a continued flash flooding threat for the state, especially over burn scars from recent fires such as the Eaton and Palisades fires. Major cities at risk from flash flooding include Los Angeles, Sacramento, San Jose and San Francisco. In addition to the threat of flooding, the storm system moving through could cause severe storms across much of the state, including isolated tornadoes. A state of emergency has been declared in Los Angeles, Orange, Riverside, San Bernardino, San Diego and Shasta counties due to flooding on Christmas Eve.
