Coastal flooding may impact beaches and low-lying shoreline areas from Santa Barbara to San Diego
Southern California’s coastline is under Coastal Flood Advisories today, August 11, as elevated water levels and coastal conditions create a risk of flooding along vulnerable beaches, shorelines, and low-lying coastal locations.
Areas Under the Coastal Flood Advisory
The advisory includes coastal areas across several Southern California counties:
- Santa Barbara County Southwestern Coast
- Santa Barbara County Southeastern Coast
- Ventura County Beaches
- Malibu Coast
- Los Angeles County Beaches
- San Diego County Coastal Areas
- Orange County Coastal Areas
Coastal Flooding Could Affect Low-Lying Areas
Coastal flooding can occur when higher-than-normal water levels push seawater farther inland than usual. Beach parking lots, waterfront roads, walkways, bike paths, harbors, and other low-lying locations may be particularly vulnerable.
Residents and visitors along the Southern California coast should remain alert for changing shoreline conditions. Water can move farther inland than expected, especially around beaches, jetties, seawalls, and other exposed coastal locations.
Beachgoers Should Use Extra Caution
If you’re heading to the beach, keep a safe distance from the shoreline and avoid walking near areas where waves are breaking over rocks, seawalls, or other structures.
Drivers should also avoid flooded coastal roads. Even shallow water can hide hazards or damage road surfaces.
Santa Barbara to Los Angeles Coast
Coastal communities from Santa Barbara County through Ventura County, Malibu, and Los Angeles County could see localized flooding in vulnerable shoreline locations.
People visiting beaches should pay attention to posted signs and local officials, particularly around low-lying access points and coastal roads.
Orange County and San Diego Coast
Further south, the advisory extends to Orange County coastal areas and San Diego County coastal areas. Popular beaches, waterfront communities, parking areas, and coastal pathways may experience localized flooding where water levels rise.
Conditions can change quickly, so visitors should monitor the latest local coastal information before heading to the shoreline.
