Additional storms, including some maintaining multicell clusters and some rotating storms seem likely along the frontal boundary slowly moving towards central Italy today. Threat for heavy rain and a tornado is in place. Storms over Ligurian bay could produce some waterspouts given the weaker wind field and good LL buoyancy.
