.Synopsis for the Central California Coast and Bays Including
the Monterey Bay...Greater Farallones...and Cordell Bank
National Marine Sanctuaries...

An upper level disturbance located off the coast of Santa Barbara
will continue east just south of our coastal waters. This system
has been associated with light precipitation and lightning. There
is still a chance of thunderstorms over the southern waters
between now and midnight. A cold front is forecast to move across
the waters late Thursday. This system may bring light rain. A
moderate to long period mixed northwesterly and southerly swell has
arrived with buoys reporting periods of 18 to 19 seconds across
the coastal waters. Later this week a very large northwesterly
swell train is forecast to move across the area. This large swell
will create hazardous conditions.
