Synopsis: PZZ500-231015- 240 PM PDT Fri Oct 22 2021 .Synopsis for the Central California Coast and Bays Including the Monterey Bay...Greater Farallones...and Cordell Bank National Marine Sanctuaries... A cold front moved through the region today and post frontal winds have veered west and weakened across the waters. The storm system associated with this front generated an area of heightened wave energy north of Cape Mendocino earlier today which has since filtered southward into our coastal waters. Buoys are showing varying heights and periods in the range of 10 to 16 feet at 14 to 17 seconds associated with this energy and reports are it has made it to the coast, bringing localized hazards to small craft vessels in the surf zone. The next, more impactful event for the waters arrives Sunday with a strong atmospheric river. Gusty southerly winds, steep waves and large swell are expected Sunday into Monday along with heavy rainfall and poor visibility. $$
