The National Weather Service has issued a high-surf advisory for the north shores of Oahu, Molokai and Maui and the north and west shores of Niihau and Kauai through 6 a.m. Tuesday.

According to the weather service, a growing west-northwest swell is expected to peak Monday morning and gradually decline through mid-week. Waves are expected to reach 12 to 16 feet on north shores and up to 12 feet on west shores, resulting in strong breaking waves, shore break, and dangerous longshore and rip currents.
