HONOLULU (HawaiiNewsNow) - A northwest swell will gradually decline on Friday, but it will still generate advisory-level surf along north and west shores of the Hawaiian islands, the National Weather Service says.
A High Surf Advisory has been issued for north- and west-facing shores of Niihau, Kauai, Oahu and Molokai; for north-facing shores of Maui; and for west-facing shores of the Big Island. The advisory is in effect until 6 p.m. Thursday.
Forecasters said surf along north and west shores will reach 16 to 22 feet on Friday morning and will decrease to 12 to 16 feet in the afternoon. Surf along west-facing shores of Oahu and Molokai will rise to 10 to 15 feet in the morning and will decrease to 8 to 12 feet in the afternoon.
The large and powerful waves from this swell have washed away a portion of Kamehameha Highway in Kaaawa, and as a result, traffic is being contraflowed in that area.
Beachgoers should still expect large breaking surf, significant shorebreak and dangerous currents that will make swimming difficult.
