The National Weather Service issued a high-surf warning this afternoon until 6 a.m. Sunday for north and west shores of Niihau, Kauai, Oahu, Molokai, Kahoolawe and Maui.
The warning was also issued for west shores of Lanai and Hawaii island.
Beaches on Kauai's north shore have been closed today due to high surf and dangerous currents. Waves up to 30 feets have been reported, according to Kauai County Ocean Safety Bureau officials.
Surf was expected to build tonight to 20 to 30 feet on north shores and 15 to 20 feet on west shores.
The weather service said waves may sweep across beaches, and warned of strong breaking waves and rip currents that may affect harbors and channels.
