A cyclonic circulation centred between Sardegna and Sicily in the Tyrrhenian Sea generated deep convection in the region of Calabria, the most southern region in continental Italy.

The Dust RGB composite imagery (Figure 1) shows the largest cloud mass brought precipitation to the southern tip of Sicily and the sea.

However, an active round-shaped cell moved north and crossed the Calabrian region, bringing torrential rain to northern parts of Calabria, causing severe flash flooding and subsequent power failures.

A state of emergency was declared in the region after a reported 160mm of rain fell in a few hours.
