A High Surf Warning has been issued. It runs from now through 9 p.m. tomorrow (Sunday) night. People can expect waves of 23 – 28 feet at all area beaches, and in excess of 30 feet at some. This also means an increase in the risk of strong Rip Currents and coastal erosion. This warning runs from north of San Francisco, south to the Big Sur Coast. People are strongly encouraged to stay off jetties, piers, rocks, and other waterside infrastructure.
