AMPL - MAXIMUM AMPLITUDE IN METERS FROM THE UNDISTURBED SEA LEVEL TO THE CREST IN SOME COASTAL AREAS (PARTICULARLY NEAR THE EPICENTER), TSUNAMI WAVES MAY BE HIGHER AND/OR ARRIVE EARLIER THAN ESTIMATED FOR NEARBY FORECAST POINTS. AUTHORITIES SHOULD BE AWARE OF THIS POSSIBILITY. THE EVALUATION OF TSUNAMIGENIC POTENTIAL AND ESTIMATED ARRIVAL TIMES FOR TSUNAMI WAVES MAY ALSO DIFFER FROM THOSE OF PTWC DUE TO DIFFERENCES IN ESTIMATED EARTHQUAKE PARAMETERS AND THE TSUNAMI FORECAST MODEL. AUTHORITIES SHOULD REFER TO EARLIER ARRIVAL TIMES FOR GREATEST SAFETY.
