A Marine Weather Statement has been issued by the National Weather Service for a very large west-northwest swell. The Weather Service in Honolulu is warning of strong harbor surges and large breaking waves at harbor entrances exposed to the swell. Some locations that could expect such conditions are the Kawaihae and Honokohau harbors.
The High Surf Warning has been extended for the west side of the Big Island. The warning is posted through Sunday at 6:00 a.m. Wave heights of 10 to 15 foot faces are expected. Expect ocean water occasionally sweeping across portions of beaches, very strong breaking waves and strong longshore and rip currents. Breaking waves may occasionally impact harbors making navigating the harbor channel difficult. Large breaking surf, significant shore break and dangerous currents will make entering the water very hazardous. Boaters should be aware of an increased number of surfers in the water.
A Small Craft Advisory has been issued for all island waters through 6:00 a.m. Sunday for winds from 15 to 25 knots and rough seas of 7 to 17 feet.
