Residents in low-lying areas, particularly near the Alamitos Peninsula and Alamitos Bay, face risks of shallow flooding, beach erosion, and localized damage. Dangerous rip currents are expected along south-facing beaches, posing hazards to swimmers and surfers. Coastal flooding concerns are highest during Sunday morning’s high tide, which could reach 7.5 feet. Additional swells from the west and southwest may prolong hazardous conditions into early next week.
