A persistent south swell will continue to produce high surf along exposed south facing shores and reefs of all islands tonight. This swell will produce moderate to strong surges in harbors exposed to the south...as well as breaking waves near Harbor entrances. Mariners are urged to use extra caution when entering or leaving port...and ensure that vessels are moored carefully due to the increased wave and surge action.
