* surf...along north and west facing shores of niihau and kauai
and north facing shores of oahu...molokai and maui...peaking at
25 to 30 feet. along west facing shores of oahu and molokai...
peaking at 15 to 20 feet. along west facing shores of the big

* impacts...high...expect ocean water occasionally sweeping across
portions of beaches...very strong breaking waves and strong
currents. breaking waves may occasionally impact harbors exposed
to the swell...making navigating the harbor channel dangerous.
precautionary/preparedness actions...
stay out of the water and well away from the shoreline along the
affected coasts. inexperienced persons should remain off beaches
and adjacent beachfront areas. large breaking surf...significant
shorebreak...and dangerous currents make entering the water very
hazardous. anyone entering the water could face significant
injury or death.
