Flood Risks and Holiday Impacts
Significant urban roadway flooding, major rock and mudslides, plus rapid rises in creeks and rivers pose high risks. Burn scar areas face debris flows that could damage infrastructure and prompt rescues.
Holiday travel faces major disruptions with expected road closures and delays during this busy period. UCLA advisories note 3-6 inches of rain in LA, up to 6-12 inches in mountains, peaking Christmas Eve and Day.
Residents in flood-prone zones should prepare, monitor updates, and heed potential Flood Warnings. Safety resources emphasize avoiding flooded roads amid high rainfall rates.
Preparation and Safety Tips
Secure outdoor items, clear drains, and avoid driving through floodwaters. Those near burn scars or low-lying areas should elevate valuables and have evacuation plans ready.
Check NWS updates frequently, as rainfall could exceed one inch per hour with thunderstorms. Long-term December averages suggest 3-5 rainy days and 53mm total rain, but this event far surpasses norms.
