The Sicily tornadoes were two tornadoes that swept the Marsala countryside in western Sicily, Kingdom of the Two Sicilies (now Italy) in early December (possibly late November) 1851. The total number of victims is unknown, but is assessed at over 500. It is one of the 10 deadliest tornadoes ever, achieving the highest death toll for a tornado event in continental Europe and the second in European history after the Valletta, Malta Tornado.
