.Synopsis for the Central California Coast and Bays Including
the Monterey Bay...Greater Farallones...and Cordell Bank National
Marine Sanctuaries...
An upper level area of low pressure will keep pressure gradients
generally light across the southern waters tonight into Monday. As
the low moves inland surface pressure gradients will increase over
the northern outer waters with increasing northwest winds for the
offshore waters from Point Arena southward towards Point Reyes
resulting in building short period seas. Lighter wind and seas
continue across the southern waters through midweek as high
pressure rebuilds.
