On March 12, 2018, an EF2 tornado struck the Italian city of Caserta, located about 30 kilometers (18 miles) north of Naples. The tornado caused damage to cars, buildings, and road infrastructure, with 15 people reported injured.
This was a classical supercellular tornado. This type of tornado forms in a specific type of supercellular thunderstorm, which has the peculiarity of having a vortex of rising air inside — called a mesocyclone, and this is where tornadogenesis starts. Rainfall in the thunderstorm produces a downdraft, called rear-flank downdraft (RFD) in this case, which enters the mesocyclone from the back. The combined updraft (from the mesocyclone) and downdraft (from the RFD) create a tornado.
