“Law Enforcement personnel in the field are also notifying specific properties about the Evacuation Warnings in recent wildfire burn scare areas effective 12/31/2025 at 11 a.m.” according to the county website. “This is due to weather forecasts and the possibility of mud and debris flows. Law enforcement personnel are making door to door contact to notify those specific properties.”

“LA County Public Works crews will mobilize storm patrols and monitor vulnerable communities. Catch basins and spreading grounds are operational and prepared to mitigate flood risk, capture, store, and beneficially reuse storm water.”
