The flooding has severely impacted transportation and local infrastructure, with closures on major roadways like the Pacific Coast Highway and disruptions to rail services. Vulnerable beach communities, particularly in Orange County, face heightened risks of property damage due to the elevated tides. Areas with minimal sandy beach buffers or previous flooding are at greater risk of significant damage. Residents in flood-prone areas are advised to move vehicles and prepare for potential water intrusion. The National Weather Service warns that tides could remain near record levels through Wednesday, increasing the likelihood of further disruptions.
