The high tides are expected to inundate homes, businesses, and critical infrastructure in low-lying areas, particularly in San Diego and Orange counties. Beach erosion and isolated structural damage are possible in other coastal regions. Vulnerable areas, such as the Long Beach Peninsula and Newport Beach, may experience severe flooding. The tides could reach record-breaking levels, with water levels potentially exceeding 8 feet in some locations. Coastal roads and infrastructure, including Highway 1 near Point Mugu, are at risk of further damage.
