Flash floods swept through several towns Friday in hilly central Italy after hours of exceptionally heavy rain, leaving 10 people dead and at least four missing. Dozens of survivors scrambled onto rooftops or up into trees to await rescue.

Floods invaded garages and basements and knocked down doors. In one town, the powerful rush of water pushed a car onto a second-story balcony, while elsewhere parked vehicles were crumpled on top of each other in the streets. Some farm fields near the sea were meters (yards) under water.

The overnight flooding left the town’s 1,300 residents without drinking water. 10 people were dead and four were missing in the flash floods. Officials said some 50 people were treated at hospitals for injuries.

In a space of a few hours, the region was deluged with the amount of rainfall it usually receives in six months, state TV said. A summer of virtually no rain meant hillsides were unusually hard and dry, so the water ran faster down the slopes, increasing its impact.

The fire department tweeted that dozens of people trapped in cars or who had climbed up to rooftops or trees to escape rising floodwaters had been rescued. Police in the town of Sassoferrato, unable to reach a man trapped in a car, extending a long tree branch to him and pulled him to safety.
