Hurricane Marie’s Offshore Surge Triggers Coastal Flooding and Dangerous Surf in Southern California
9/7/2026, 10:26:55 PM
Core Event: Offshore Storm Generates Flooding and High Surf
Hurricane Marie, downgraded to a tropical cyclone while remaining offshore, produced powerful surf and elevated tides that breached coastal berms along the Los Angeles and Orange County shoreline. In Long Beach, Seal Beach and the Alamitos Peninsula, waves swept over eight-foot protective berms, inundating streets, parking lots and low-lying homes. Residents used pumps and sandbags to move standing water into the sewer system, while city crews began rebuilding the damaged barriers the following morning.
Background & Context
Marie originated off the coast of Mexico on Tuesday and, despite forecasts that it would track westward, its outer circulation generated strong on-shore winds and swell. The National Weather Service warned that, even without landfall, the system would bring rain, high surf and rip-current hazards to the region.
Data & Statistics
- Surf heights of 6–10 feet, with Zuma Beach reporting 10-foot waves.
- Rainfall totals of a quarter-inch to an inch across Los Angeles County.
- Eight-foot berms were completely washed away in several locations.
- The Long Beach Fire Department deployed portable pumps to remove floodwater.
- Newport Beach lifeguard battalion chief Adam Yacenda recorded 177 rescues on Saturday.
On-the-Ground Reports
Long-time peninsula resident Jen described blocked storm drains causing water to overflow onto her block after the swells arrived around 2 p.m. Ashley Brown observed debris being hurled aloft, saying, “Everything that it’s throwing up at you with every wave is something that somebody is getting hit with, or a board that is coming off the boardwalk that is going up 10 feet in the air.”
Official Statements & Responses
- The Long Beach city health officer issued a three-day advisory prohibiting swimming at any city beach or bay due to runoff-related water quality concerns.
- Assistant Chief Jake Heflin of the Long Beach Fire Department confirmed additional pumps and crews were dispatched to extract floodwater and begin berm reconstruction on Monday.
- Seal Beach Police Department announced the closure of the 8th Street and 10th Street beachfront parking lots through Wednesday, while keeping the municipal pier open.
- NWS meteorologists Rose Schoenfeld and David Gomberg warned of “life-threatening” surf conditions, strong rip currents and the possibility of localized thunderstorms, advising the public to stay near lifeguards and avoid rock jetties.
Conflicting Reports & Gaps
Sources differ on the maximum wave height: ABC News cites “up to 10 feet” at several south-facing beaches, while the Los Angeles Times reports “6- to 8-foot” waves as the prevailing condition. Flood impact descriptions also vary; ABC 7 describes “widespread” street flooding, whereas the Los Angeles Times notes “isolated road closures.” Comprehensive damage assessments and long-term infrastructure plans remain pending.
