The 26-year-old woman was driving home at around 2:00 am Sunday when the mini-tornado lifted her car and sent it crashing against a railing.

Further north, a 45-year-old Norwegian competing in an ultramarathon in the Dolomite Mountains died after being hit by lightning as he ran at 2,000 metres altitude on Saturday afternoon.
And on Sunday, near Arezzo, south of Florence in the northern Tuscany region, a 70-year-old man died after his car got caught by flash-flooding. The emergency services found his body in a mud-filled canal.

Coldiretti, Italy's main agricultural organisation, said hail storms over the last 24 hours had caused millions of euros worth of damage across the country. Worst hit was Arezzo province, they said.
Orchards, as well as fields of tobacco, sunflowers and corn were completely destroyed, they said.
