The National Weather Service has issued a high surf advisory for south-facing shores of all islands through 6 a.m. Monday.

The advisory was issued at 3:27 p.m. Sunday. Last week a slow-moving storm near New Zealand generated a south-southwest swell that continues to move through the Hawaiian coastal waters.

Surf along Oahu’s Waianae coast is expected to build to 5 to 8 feet with locally higher sets along south-facing shores.

Swimmers should expect strong breaking waves, shore break and strong currents. Beachgoers are urged to heed advice from Ocean Safety officials and exercise caution.
