Abstract
The late snowstorm in southwestern Croatia in May 1991 was associated with the Alpine lee cyclogenesis. The synoptic analysis has confirmed the theoretical concept of lee cyclogenesis which emphasise the role of an oreigenic cold air blocking on the windward side of the Alps with a simultaneous displacement of the local maximum of high level potential vorticity. However, it has been found that the basic causes of a high precipitation amount and a very late snowstorm were processes of a subsynoptic scale, not detected in the
standard synoptic analysis. We are trying to prove the association of severe storm with the fast development of a mesoscale vortex over the Adriatic.
