inexperienced mariners...especially those operating smaller
vessels should avoid navigating in these conditions.

a small craft advisory for rough bar means that wave conditions

a gale warning means winds of 34 to 47 knots are imminent or

recommended that mariners without the proper experience seek safe
harbor prior to the onset of gale conditions.
