 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

                     0307 AM HST FRI 11 MAR 2011

MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.
