Cutoff low brings thunderstorms, heavy rainfall and numerous waterspouts to Italy, Slovenia and Croatia

A large and complex cutoff cyclone formed over the northern & central Mediterranean after frontal passage on September 16. The system has been causing locally intense rainfall across Italy, western Slovenia and particularly northwestern Croatia (Istra peninsula and Kvarner). Flooding has been reported from many locations. Also, numerous waterspouts have been reported from the coasts of the Adriatic, Ligurian and Tyyrhenian seas over the past two days. Photographers also captured many impressive photos of lightning! Check out the gallery below!
