The San Mateo County coast is experiencing huge swells and Mavericks surfers are ready.  Large breakers are expected to continue for the rest of the week at the famed surf spot just north of Half Moon Bay.  "The Chronicle" says although there is no official announcement, organizers spent last night doing preliminary work and contacting the 24 invited surfers for the world-famous competition.  Organizers are hoping to hold the event Friday.  The National Weather Service issued a high-surf advisory for the Bay Area for Thursday through Friday evening.
