the national weather service in honolulu has issued a high surf
warning, which is in effect until 6 am hst friday. the high surf
advisory is no longer in effect. 

* surf...20 to 30 feet along north facing shores and 10 to 15 
  feet along east facing shores of niihau kauai oahu molokai maui 
  and the big island.

* timing...building through the day on wednesday...peaking on
  thursday...and then declining on thursday night and friday.

* impacts...high...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 dangerous.

precautionary/preparedness actions...
large breaking surf, significant shorebreak, and dangerous 
currents make entering the water very hazardous. anyone entering 
the water could face significant injury or death. boaters should 
be aware of an increased number of surfers and body boarders 
utilizing the harbor channel to access surfing areas.
