Remnants of Tropical Storm Rachel triggered severe coastal flooding and infrastructure damage across Southern California this weekend, forcing residential evacuations and prompting local emergency responses. High surf caused significant erosion, damaging homes in Long Beach and closing state parks as the storm’s rainfall arrived.
Storm Surge Batters Long Beach
City inspectors have red-tagged 13 structures across eight buildings in the 6400 and 6500 blocks of Seaside Walk, declaring them unsafe for occupancy after high surf and tides breached protective berms and damaged the boardwalk. An additional building received a yellow tag.
City crews have been working to reinforce a damaged bulkhead with a crane and 30 heavy-duty sandbags, each weighing 3,000 pounds. Mayor Rex Richardson confirmed that a three-month project to rebuild the beach and bring in more sand begins next week.
Mayor Rex Richardson emphasized that safeguarding local residents remained the top priority as severe erosion impacted the Peninsula community.
Dan Fox, president of the Structural Engineers Association of Southern California, explained that the pounding waves stripped soil from beneath building foundations and substructures, creating a risk of shifting and destabilizing the structures. Local resident Gabriella Holt observed that ocean water reached areas she had never seen affected during her twelve years in the neighborhood.
Parks Close Along Orange County Coast
In Orange County, California State Parks temporarily closed sections of Crystal Cove State Park and San Onofre State Beach.
District Superintendent Scott Kibbey noted that the agency’s immediate priority centered on protecting public safety while carrying out emergency actions to safeguard park infrastructure and maintain public access wherever conditions permitted. State Parks officials stated that reopening timelines will depend heavily on subsequent ocean conditions, formal damage evaluations, and the successful completion of required emergency repairs.
Heavy Rains Hit San Diego County
The National Weather Service reported three-day totals exceeding 6 inches in parts of the East County highlands, such as Palomar Mountain, while coastal areas saw more modest amounts, including 1.92 inches in Oceanside and 1.04 inches at San Diego International Airport.
Advisories Remain in Effect
The National Weather Service has downgraded previous warnings to a coastal flood advisory, which is expected to remain in effect through at least Tuesday afternoon, even though the National Hurricane Center issued its final advisory on Sunday, October 11.
“Minor to moderate coastal flooding is likely to continue through at least Tuesday.”

Laguna Beach City Manager Dave Kiff remarked that early morning weather forecasts proved slightly off regarding the rain, though the city maintained a response with police, fire, and municipal personnel monitoring high and low tides. Meanwhile, local observers in Oceanside gathered near the pier and along The Strand to watch the high surf impact the coast.
Meteorologists expect drier, warmer conditions to return by the end of the week, though forecasters are already monitoring the potential for Santa Ana winds strengthening by Friday and Saturday.
