San Francisco Frontiers - Eight dead, Grand Prix postponed after flooding in northern Italy

"The city is on its knees, devastated and in pain," said Gian Luca Zattini, the mayor of Forli, a city near Bologna where three people were confirmed dead earlier Wednesday. "It's the end of the world."

Emilia Romagna's vice president, Irene Priolo, later told reporters that a total of eight people had died, with several others missing.

Two of the bodies in Forli were recovered by divers on Wednesday morning, as part of a huge rescue effort involving emergency services and the armed forces.

Emilia Romagna, one of Italy's richest regions, had already been hit by heavy rain just a fortnight ago, causing floods that left two dead.

This time, around 50 centimetres (20 inches) of rain fell within 36 hours in Forli, Cesena and Ravenna -- around half the normal annual rainfall, a situation "with few precedents", Italy's Civil Protection Minister Nello Musumeci said.

"It is still a very critical situation," he told reporters, adding that while the rain was still falling, it was expected to lighten during the day.

The flooding caused the cancellation of the Formula One Emilia Romagna Grand Prix, which had been set for on Sunday in Imola.

Organisers said they could not guarantee the safety of fans, teams and staff.

"It would not be right to put further pressure on the local authorities and emergency services at this difficult time," they said.

- 'We're scared' -

Regional President Stefano Bonaccini said Emilia Romagna had been hit "like an earthquake".

Rescue workers had worked through the night to save children, the elderly and the disabled from the rising waters.

"We're scared, this time we're scared," said Simona Matassoni, the owner of the Hotel Savio in Cesena, which has so far escaped flooding.

"I was born here, I've seen lots of full rivers, but never anything like this," she told AFP by telephone on Wednesday morning, adding that it was still raining.

"At the moment we're crossing our fingers... but another flood is expected, so who knows (what will happen)."

Some 3,000 people had been evacuated from their homes in Bologna, while the mayor of Ravenna said some 5,000 people were being evacuated as a precaution. Around 50,000 people were without electricity.

Twenty-one rivers in the region had broken their banks between Tuesday and Wednesday, while 36 local authorities reported flooding and 48 reporting landslides.

The civil protection agency urged "maximum caution", as mayors warned people to stay on high ground.

In Forli, an AFP photographer saw people in a state of shock as they fled on Tuesday night through floodwaters in the dark in their bare feet.

Images showed streets transformed into rivers, and firemen moving people to safety in rubber dinghies.

Elsewhere, muddy waters rushed at great speed under the arches of the covered walkways in Bologna, while locals in Cesena swam down a road to rescue a three-year-old child.

"We absolutely must not lower our guard," Cesena mayor Enzo Lattuca said on Facebook.

Residents "must not under any account go into basements or cellars", and should "stay out of ground floors if possible", he said.

Much of northern Italy suffered a drought last winter, on top of a record lack of rain last summer that ruined harvests.

However, spring has been wetter and colder than normal across the country.
