HONOLULU (HawaiiNewsNow) - The National Weather Service has extended a high surf advisory until 6 a.m. Monday for the south-facing shores of all islands.
Forecasters expected wave to remain in the six to ten-foot face range through Sunday before subsiding Monday.
The Weather Service also has posted a Marine Weather Statement saying, "This swell will produce moderate to strong surges in harbors exposed to the south as well as breaking waves near harbor entrances. This swell has already caused vessels near Mala wharf on Maui to break free from their moorings. 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."
The first south-shore swell of the summer season has surfers stoked.
