HIDRALERTA is a forecast, early warning and risk assessment system for port and coastal areas that uses estimates of sea-waves and water levels to evaluate overtopping/flooding events and risks associated with mooring ships. As a warning system, it is especially important that it gives an appropriate response in mild (with no false alarms) and storm conditions alike. This work presents the developments made so far to validate the system under storm events, with its application in the simulation of hurricane Lorenzo and the storms Elsa and Fabien. It can be concluded from the qualitative analysis that was performed that the warnings emitted by the system were in agreement with the damage/occurrences reported at the site. These results serve to reinforce confidence in the HIDRALERTA system. The distinguishing feature of this work is that the risk assessment is based on specific parameters related to the actual risk being predicted, such as overtopping discharges, or ship’s mooring loads, and not only in met-ocean parameters.
