The high tides pose a significant risk to coastal communities, with potential flooding of homes, businesses, and critical infrastructure. Areas already affected by erosion, such as Newport Beach and Long Beach, are particularly vulnerable. Damage to roads, including Highway 1 near Point Mugu, and exposure of buried infrastructure are concerns. Rising sea levels, driven by warm ocean temperatures and El Niño, exacerbate the situation. Residents in flood-prone areas are advised to take precautions as tides could restrict access to beaches and coastal zones.
