Evidence is presented in this paper which supports the use of the extremal Rayleigh distribution for predictions of the largest wave height in a hurricane with time varying intensity. A formula is developed for the maximum wave distribution function in time-varying storms and computed for a large number of historical hurricanes, and the external Rayleigh function was found to be a very accurate approximation in allcases. Two parameters are shown to be interpretable in terms of an equivalent uniform intensity storm as the reciprocal of the logarithm square wave height and the logarithm of the number of waves in the storm, respectively. Data from hurricane Carla was analyzed as a case study to determine the parameters which best described the probability behavior of the larger waves in each 20 minute record. Statistical formulas and tables are given to facilitate probability use of the extremal Rayleigh probability law in coastal engineering and hurricane research.
