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

Compressed marine inversions and an influx of moisture across the
coastal waters is resulting in areas of fog that is also extending
into the bays. Onshore pressure gradients will increase today
causing a general increase in winds over the bays this afternoon
into tonight. A small craft advisory will continue over the southern
inner coastal waters today and tonight. 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 seconds across
the coastal waters. Late this week a very large northwesterly swell
train is forecast to move across the area. This large swell will
create hazardous conditions.
