HONOLULU (HawaiiNewsNow) - The National Weather Service issued a high surf warning which is in effect from noon Tuesday through 6 p.m. Wednesday.
A northwest swell will produce warning level high surf for north and west facing shores along Niihau, Kauai, Oahu, Molokai and the north facing shores of Maui.
Forecasters say the northwest swell will continue to build through Tuesday peaking Tuesday night and Wednesday with peak surf heights exceeding warning levels.
The weather service said waves along north shores are expected to reach 25 feet and 20 feet along west facing shores during the peak of the swell.
The waves could result in rip currents which can easily overpower even strong swimmers, and cause coastal erosion along shores exposed to the northwest swell.
The weather service say with this early season swell, significant erosion of sand can be expected along beaches where sand has accumulated during the summer months.
