...small craft advisory for hazardous seas now in effect until
4 am pst sunday...

* winds...southwest 15 to 25 knots with gusts as high as 30 knots
  through this evening. local gusts 30 to 40 knots near heavy
  showers or thunderstorms. wind decreasing overnight but
  increasing to northwest 15 to 25 knots with gusts to 30 knots by

  feet through at least sunday morning. 

* thunderstorms...isolated thunderstorms through tonight.  

precautionary/preparedness actions...

a small craft advisory for wind means that wind speeds of 21 to
33 knots are expected. inexperienced mariners, especially those
operating smaller vessels should avoid navigating in these
conditions.

a small craft advisory for hazardous seas means that waves are
expected to be hazardous to small craft. mariners should avoid
shoaling areas. long period swell can sharpen into large breaking
waves in shoaling areas. it is not unusual for waves to break
much farther from shoaling areas than is normally experienced.
remember, breaking waves can easily capsize even larger vessels.
