...GALE WARNING REMAINS IN EFFECT FROM 1 PM TUESDAY TO 10 AM PST

* WAVES...West swell from 10 to 12 feet tonight will subside to

  feet will build on Tuesday. Steep and hazardous seas will
  continue to build Tuesday night.

* WINDS...Southerly gusts to 40 kt possible Tuesday afternoon.
  Gale force winds are much more probable Tuesday night.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Gale Warning means winds of 34 to 47 knots are imminent or
occurring. Operating a vessel in gale conditions requires
experience and properly equipped vessels. It is highly
recommended that mariners without the proper experience seek safe
harbor prior to the onset of gale conditions.

A Small Craft Advisory means that wind speeds of 21 to 33 knots
are expected to produce hazardous wave conditions to small craft.
Inexperienced mariners, especially those operating smaller
vessels should avoid navigating in these conditions.
