During the night between the 8 and 9 December 2006 the
seawall of the Savona harbour (Liguria Region in north west of Italy) was
overtopped by waves. In this work the "Savona flash sea storm" has been
studied by analyzing the data recorded by meteo-marine observing stations and
the data produced by high resolution meteo-marine numerical models. The data
show that, due to the presence of a fast moving low pressure system, the
event was characterized by a rapid transition and interaction between two
different regimes of winds and related sea states.

The results of the study suggest that the most damaging dynamics of the event
could be correlated to a bi-modal structure of the wave spectrum. Based on
this the authors suggest that a deeper study of the spectral structure of sea
storms could lead to define new operational forecasting tools for the
preventive evaluation of sea storms damaging potential.
