...small craft advisory for winds now in effect until 10 pm pst
sunday...
...small craft advisory for hazardous seas remains in effect
until 6 am pst monday...

* winds...west to northwest 15 to 25 knots with gusts to 30 knots.
  winds ease a little through the evening and then increase to 20
  to 25 knots with gusts to 30 knots late tonight and continue
  through sunday.

  seas build to the mid teens sunday. seas likely to remain above

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.
