Deep and stationary convection occured over the Versilia region (Italy) on 19 June 1996 producing heavy precipitation for fourteen hours (424 mm as a maximun). The stationary supercell, initially formed at the coast line, grew in an environment of clockwise hodograph curvature and its development was favoured by the weak flow towards the Apuane Alps.
This type of phenomena highlights the need for accurate and spatially dense observations in order to be studied.
We collected non-standard data and performed specific numerical simulations with different LAMs to improve investigastion of a case which caused many injuries to the local people.
