The high tides pose a significant risk to low-lying areas, including homes, businesses, and critical infrastructure. Roads may be closed, and flooding is expected in vulnerable coastal regions. Newport Beach and Long Beach have already experienced severe flooding, with waves damaging homes, parking lots, and boardwalks. The Balboa Peninsula and Newport Harbor islands are particularly at risk. Coastal erosion remains a concern, especially for infrastructure like rail lines and highways. Beachgoers and residents are advised to exercise caution, as high tides can create dangerous conditions on jetties, seawalls, and beaches.
