The high tides are causing significant flooding in low-lying coastal areas, leading to road closures and potential damage to shoreline infrastructure. Residents in affected areas, particularly in Pacific Beach and Mission Bay, are advised to take precautions to protect their properties. The NWS has warned of the risk of shoreline erosion and has urged residents to avoid driving through flooded areas or around barricades. While some North County beach communities have fared better due to higher elevation, areas closer to sea level are experiencing more severe impacts.
