A depth-averaged, numerical storm-surge model has been developed and configured to provide a stand-alone system to forecast tropical cyclone storm-surges. The primary data requirement for modelling storm surges is accurate surface wind and atmospheric pressure fields, in particular in the vicinity of maximum winds. These fields are inferred from an analyticalempirical cyclone model which require only cyclone position, intensity and size. The model has been adapted to run on a personal workstation in a few minutes. The storm-surge model was tested in hindcast mode on tropical cyclones which gave significant surges over the French overseas territories during the last 15 years. This model is now in operation in the French Antilles, in New caledonia, in the French Polynesia and in La Reunion.
