A high surf advisory is now in effect for portions of Kaua‘i and Ni‘ihau.
The National Weather Service in Honolulu issued the advisory for north- and west-facing shores of both islands. It is effect through 6 a.m. Thursday, Feb. 17.
A high surf warning that was previously issued has been canceled.
Surf of 15-20 feet is forecast along north-facing shores, with surf from 14-18 feet expected along west-facing shores.
According to a National Weather Service alert, a west-northwest swell has been subsiding but will continue to generate large breaking waves along most north- and west-facing shores of the islands through tonight.
Expect strong breaking waves, shore break and strong longshore and rip currents, which will make swimming difficult and dangerous.
Beachgoers, swimmers and surfers should heed all advice given by ocean safety officials and exercise caution.
