HONOLULU (HawaiiNewsNow) - The National Weather Service has issued a High Surf Warning for rapidly rising surf along the north and west shores of the smaller islands.
The Warning is in effect for the north and west shores of Niihau and Kauai, where waves are expected to rise to 20 to 30 feet.
A High Surf Warning is also in effect for the north and west shores of Oahu and Molokai and the north-facing shores of Maui. Surf on the north shores will build Tuesday through Wednesday from to 20 to 30 feet, while west shores on Oahu and Molokai will have surf rising to 15 to 20 feet.
The warning is set to expire at 6 p.m. Wednesday.
A High Surf Advisory has also been issued for west-facing shores of the Big Island until 6 p.m. Wednesday. Waves are expected to be between 8 to 10 feet through Wednesday.
Forecasters said the impacts from the surf will be high, and include ocean water occasionally sweeping over beaches, very strong breaking waves and strong long shore and rip currents. Breaking waves may also affect harbor entrances, making it dangerous to navigate harbor channels.
The dangerous conditions mean that only highly experienced persons should enter the water. Inexperienced persons should remain off beaches and adjacent beachfront areas.
