Original post:

A High Wind Advisory has been canceled and a High Surf Warning remains in effect until 6 p.m.

A powerful northwest swell will gradually lower today, the National Weather Service reports. There are currently large breaking waves of 20 to 25 feet along north-facing shores and 15 to 20 feet along west-facing shores.

Beachgoers should expect very strong breaking waves and powerful currents. Waves breaking in channel entrances may make navigating the channels dangerous.

The public is advised to 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.

Additionally, a small craft advisory remains in effect until 6 p.m. for all Hawaiian waters and channels except Ma‘alaea Bay.

According to NWS, seas are 10 to 14 feet. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in these conditions.
