High tides of around 7 feet combined with larger than average surf could cause minor coastal flooding today along low-lying beaches in San Diego and Orange counties, National Weather Service forecasters predicted.
Minor coastal flooding and beach erosion could occur around high tide tonight and Monday evening, mainly on south and southwest facing shores, according to the National Weather Service.
Tides were expected to reach 7.4 feet at 8:56 p.m. and again at 9:42 p.m. Monday at Navy Pier, in downtown San Diego.
Moderate beach erosion and minor flooding could affect low-lying areas and parking lots in susceptible areas that included La Jolla, Del Mar and Cardiff-by-the-Sea near Highway 101, the NWS said.
Surf heights of 3-6 feet were also expected on south-facing beaches as a long-period swell was expected to build over coastal waters this afternoon, the NWS reported.
The National Weather Service in San Diego issued a coastal flood advisory from 5 p.m. tonight to 4 a.m. Tuesday. Residents and businesses in areas susceptible to coastal flooding were advised to take precautions.
The threat of coastal flooding was expected to diminish late Tuesday morning, the NWS said.
