.Synopsis for the Central California Coast and Bays Including
the Monterey Bay...Greater Farallones...and Cordell Bank National
Marine Sanctuaries...
Expect hazardous marine conditions through the weekend as winds
and swells build. A weak storm system has arrived, bringing light
rain and moderate to strong winds with strong to near gale force
gusts. Gale force gusts are possible as frontal passage occurs
but, given the speed of the cold front, they are expected to be
short lived with winds diminishing quickly. Winds diminish by
early Friday with moderate northerly winds expected into next
week. Seas build to 10 to 15 feet Thursday and remain elevated
into early next week. Elevated seas will be prolonged by the
arrival of two distinct rounds of long period northwesterly swell.
