Rome: At least five people have died in violent rainstorms sweeping across Italy on Sunday, with the Tuscan city of Livorno taking the brunt of the flooding, fire services said.

Four people from the same family were found dead in a flooded house in the city, where 40 centimetres of rainfall in four hours transformed streets into rivers and washed away cars.

The Corriere della Sera daily said the dead were a little girl, her parents and a grandparent.

A fifth body was found in an area devastated by landslides. Three other people were missing, the fire brigade said.

“The situation is very difficult, it’s critical. We fear a disaster,” Livorno mayor Filippo Nogarin said.

Italy’s civil protection service issued a code orange alert for Florence as the storms, which began in northern Italy overnight, swept down the country towards the south.

Underpasses were being closed as a precaution in the capital, Rome.

Coldiretti, Italy’s main agricultural organisation, said the bad weather was aggravated by coming hard on the heels of a drought that had left the land drier than usual and unable to soak up the rains.

Rainfall in Tuscany in particular had been down 57 per cent this summer, it said.

“The tropicalisation of the climate is causing an increase in extreme weather events, with heatwaves, heavy cloud bursts and violent hailstorms which are damaging the national agricultural production,” Coldiretti said.

It put the cost of the damage at more than €14 billion (Dh61 billion) in the past 10 years.
