Also forecast is long-period northwest swell Wednesday through Friday, with a potential for high surf on west- to northwest-facing beaches, an NWS statement said. This combination could very well bring local coastal flooding to parts of Central and Southern California all this week. It’s expected to also impact Delaware beaches and lower Delaware Bay. “If they are affected by waves in high surf events, it’s more likely this week because of the higher tides”.
A National Weather Service coastal flood advisory is scheduled to remain in effect until 9 p.m. Thursday.
He says the surf should start to subside by Thursday afternoon.
Coastal areas in Seal Beach and Sunset Beach in Huntington Beach will be especially susceptible to flooding.
San Diego will experience the same as Los Angeles and Orange Counties.
Warm temperatures are expected today.
Higher-than-average tides along the San Diego County coastline may cause minor flooding in low-lying areas like beach parking lots and nearby streets Wednesday. Swimmers should avoid swimming in areas of large shore break and always swim near a lifeguard.
