Synopsis: PZZ500-201015- 243 PM PDT Tue Oct 19 2021 .Synopsis for the Central California Coast and Bays Including the Monterey Bay...Greater Farallones...and Cordell Bank National Marine Sanctuaries... An approaching cold front will move across the waters between this evening and tomorrow morning. Winds have become southerly and are gradually strengthening across the waters.

These strongest winds are anticipated just ahead of the front late this evening through the overnight period. Steep to very steep wind waves of 8 to 12 feet are possible with these strongest winds and are hazardous for small craft vessels.
