Genoa low

A Genoa low (also known as Genoa cyclogenesis, Ligurian depression, or V(5)-track cyclone) is a cyclone that forms or intensifies from a pre-existing cyclone to the south of the Alps over the Gulf of Genoa, Ligurian Sea, Po Valley and northern Adriatic. Vb cyclones are rare events which occur on average only 2.3 times per year.
