EVALUATION 

 A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG
 COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION
 SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY. 

 A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE
 CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD
 COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE
 INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS
 CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST.
 TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT
 RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI
 WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL
 QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE
 CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED
 BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH
 TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD. 

 THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS 

                     1119 AM HST SAT 27 FEB 2010 

MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.
