  WARNING WILL NOT EXPAND TO OTHER AREAS OF THE PACIFIC UNLESS
  ADDITIONAL DATA ARE RECEIVED TO WARRANT SUCH AN EXPANSION.

  FOR AFFECTED AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO
  HOURS AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE
  NOT OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN
  ASSUME THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL
  STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS.
  AS LOCAL CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE
  ACTION THE ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL
  AUTHORITIES.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
