Summary

Tropical Storm Rachel brought dangerous surf, high tides, and coastal flooding to the Southern California coast in early October 2026. Ocean water rushed across the Balboa Peninsula, submerging Balboa Boulevard and surrounding residential streets under at least a foot of saltwater, with videos documenting the flooding conditions. Long Beach and Newport Beach experienced significant damage, including broken protective bulkheads, flooded homes, and severe beach erosion. Authorities in Long Beach and San Diego opened sandbag distribution sites and deployed emergency pumps to prepare for and respond to the flooding. Newport Beach closed all city beaches and piers due to the coastal hazards. The National Weather Service issued coastal flood advisories and warnings for Orange County and Los Angeles County beaches, with the greatest flooding concerns expected on Sunday mornings as high tides exacerbated the storm's effects. The storm also threatened to bring heavy rain and flash flooding to inland areas of Southern California.
