The unusually high tides pose risks to roads, homes, businesses, and critical infrastructure along the Southern California coast. Vulnerable areas, including the Balboa Peninsula and Newport Beach, may experience significant flooding and erosion. Residents in low-lying areas are urged to prepare for potential property damage and disruptions to daily activities. Rail services along the Orange County Line will be suspended south of Laguna Niguel/Mission Viejo station from Monday through Friday due to the elevated tides.
