Storm Swells Flood SoCal Coast and Trigger Long Beach Evacuations

Lingering swells from Tropical Storm Marie remain hazardous offshore, with forecasts showing a rapid shift to hot, humid conditions midweek.

Overview

  • Over the Labor Day weekend, long‑period swells from the distant Tropical Storm Marie produced unusually large surf and life‑threatening rip currents that drove lifeguards to log hundreds of rescues and thousands of warnings.
  • Monday evening the Long Beach Fire Department ordered about 20 homes on the Seaside Walk between 63rd and 67th Place to evacuate after waves compromised the seawall and damaged the boardwalk while building inspectors began structural assessments.
  • Coastal infrastructure and properties sustained visible damage: sand berms were overtopped, boardwalk wood splintered, streets and garages filled with sand and water, a Malibu driveway collapsed and a Metrolink track segment was damaged and briefly closed for repairs.
  • Public‑health and safety agencies warned beachgoers to avoid ocean contact for roughly 72 hours after the rain because of runoff‑related bacteria risks and kept coastal flood and high‑surf advisories in effect through Tuesday evening.
  • Forecasters warn the hazard sequence is not over: Marie is expected to weaken offshore but its moisture will combine with a building high‑pressure ridge to produce intense heat and oppressive humidity midweek, and unusually warm coastal waters tied to a developing El Niño are raising tide levels and risk for future swells.
