LIHU`E, KAUA`I (Ben Caxton) — The National Weather Service has issued a High Surf Warning for all north- and west-facing shores of Kaua`i and Ni`ihau through Sunday evening. A large northwest swell is forecast to build rapidly today, producing warning level 25 to 35-foot waves on the exposed north and west facing shores of the island. This swell is forecast to peak this evening and hold into Saturday night before gradually subsiding. The weather service says to expect ocean water to be surging and sweeping across beaches, coastal benches, and lava flows with powerful longshore and rip currents will be present at most beaches. Large breaking waves and strong currents will also impact harbor entrances and channels causing challenging boat handling. Entering the water in these areas during the High Surf Warning is very hazardous and could cause serious injury or death. Spectators are also advised to use extreme caution, as large breaking waves could make it dangerous for those standing along the shoreline.
