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,
and/or seas 7 feet or greater, are expected to produce hazardous
marine conditions to small craft. Inexperienced mariners,
especially those operating smaller vessels should avoid
navigating in these conditions. 

A sudden onset of rough seas may cause hazardous conditions,
which may occur suddenly at jetties and inlets. These conditions
could catch boaters by surprise. Boaters should use cautions when
entering or exiting the inlets and jetty areas.
