Update: High surf advisory upgraded to warning for north- and east-facing shores

11:28 a.m. Feb. 2 update: A high surf warning is now in effect for north- and east-facing shores and a surf advisory is in place for west-facing shores. The advisory-level surf is in effect until 6 p.m. Sunday.

According to the National Weather Service in Honolulu, a north-northeast swell of 10-20 degrees will produce advisory-level surf along exposed shores of most islands through Sunday.

Dangerously large breaking waves of 22 to 26 feet is expected for north-facing shores and 12 to 16 feet for east-facing shores.

Very strong breaking waves and powerful currents should be expected. Waves breaking in channel entrances may make navigating the channels dangerous.

Stay away from the shoreline along the affected coasts. Be prepared for road closures. Postpone entering or leaving channels affected by the high surf until the surf subsides.
