HONOLULU (HawaiiNewsNow) -Surf is still dangerously large along north and west shores as a powerful swell begins to decline.
The National Weather Service has issued a high surf warning until 6 p.m. Wednesday for north- and west-facing shores of Kauai, Niihau and Molokai, and for north-facing shores of Maui.
A high surf advisory is also in effect for north shores of the Big Island until 6 p.m. Wednesday.
Surf will rapidly rise up to 30 feet along some north and west shores, forecasters said.
Forecasters said surf is expected to hold through Wednesday morning, then slowly subside in the afternoon through Thursday. It will remain at advisory levels through Thursday.
Forecasters warn that the large surf and above-normal high tide levels could increase the risk for beach erosion and water over coastal roadways.
This is the latest in a series of swells that’s been giving big-wave surfers a chance to participate in surfing competitions this season.
