Hurricane Marie’s Offshore Surge Triggers Coastal Flooding and Dangerous Surf in Southern California
9/8/2026, 6:27:23 AM
Core Event: Offshore Storm Generates High Surf and Flooding
A tropical cyclone that formed off Mexico’s coast intensified into Hurricane Marie before weakening while remaining hundreds of miles offshore. The system pushed a strong southerly swell toward Southern California, producing 6- to 10-foot waves that breached berms, inundated low-lying streets and caused power outages across multiple coastal communities. The high surf persisted through the Labor Day weekend, prompting a high-surf advisory that remained in effect through the following Tuesday.
Background & Context
Meteorologists noted that Marie’s core stayed far from the California shoreline, yet its moisture plume interacted with an active jet stream, delivering light rain and elevated tides. The National Weather Service warned that the combination of high surf, strong rip currents and astronomical tides could generate moderate risk of coastal flooding in vulnerable spots such as Long Beach’s Alamitos Peninsula, Avalon and Malibu.
Data & Statistics
- Wave heights ranged from 6 feet on west-facing beaches to 10 feet on south-facing stretches such as Zuma Beach.
- Long Beach crews documented that eight-foot berms were completely washed away.
- Lifeguard battalion chief Adam Yacenda reported 177 rescues on Saturday, far above the typical weekend average for the county.
- About a quarter-inch of rain fell across most of Los Angeles County, with higher elevations receiving up to an inch.
Official Statements & Responses
The Long Beach Fire Department deployed additional portable pumps to remove standing water and begin rebuilding compromised berms. The city’s health officer issued a three-day advisory prohibiting swimming at any local beach or bay due to runoff-related water-quality concerns. Seal Beach police confirmed the closure of the 8th Street and 10th Street parking lots through Wednesday.
On-the-Ground Reports
Residents described rapid flooding as sand clogged storm drains, causing water to back up onto streets and into garages. Long Beach resident Cole Hill noted power loss and structural damage, while Ashley Brown highlighted debris being hurled up to 10 feet in the air. In Seal Beach, Clifford Scarborough said waves that are normally only a foot or two surged to “crazy” levels, prompting volunteers to construct a temporary berm and pump seawater out.
Conflicting Reports & Gaps
Sources differ on the maximum wave height observed. The Los Angeles Times quoted meteorologist David Gomberg reporting 10-foot waves at Zuma Beach, while another report described six- to eight-foot surf at East Beach. Both figures appear in official advisories, indicating a range rather than a single definitive measurement. Rain forecasts of a quarter-inch for most areas were exceeded in some foothill locations, where up to half an inch was recorded.
Why It Matters
The event highlights the vulnerability of coastal infrastructure to offshore storm surges, even when a tropical system remains distant. Damage to berms and storm-drain capacity revealed gaps in flood-mitigation planning for low-lying neighborhoods and strained emergency services during a holiday weekend.
What’s Next
The NWS maintains a high-surf advisory through Tuesday, with expectations that Marie will continue to weaken and transition to a post-tropical remnant low by mid-week. Swells are projected to persist for several days, keeping rip-current and coastal-flood risks elevated. Local agencies will keep pumps and personnel on standby until water levels recede and damaged berms are restored.
