Rome has been hit by sporadic, but heavy, downpours and thunder and lightning this week, with parts of the city being flooded.
The unsettled weather is forecast to last until Thursday.
Italy’s storms often prove to be treacherous. In July last year, a 12-year-old boy died after being struck by lightning while playing football on the beach.
Later that summer, 40,000 lightning strikes were recorded during a single day of storms.
Meanwhile, a six-year-old boy from northern Italy survived after being hit by lightning while having a bath last October.
