Hundreds of Aussie homes damaged in overnight floods

Hundreds of homes in Australia's Victoria state have been damaged by overnight floods brought on by a severe thunderstorm.

State Emergency Service (SES) volunteers were called out to attend hundreds of calls, with vast majority of them coming from the state's west near Geelong and the Surf Coast.

Marc Dorey, an SES spokesperson, said there were reports of flash flooding, building damage and flooded homes.

"We've pretty much cleared all of the jobs overnight," Dorey told News Limited on Tuesday. "Most of the calls came through in a couple of hours and it took a while to churn through those."

"There were a number of cars that became stuck as they've driven into flood water," Dorey said.

The spokesperson said that volunteers were bracing for another spike of calls on Tuesday morning as residents woke up and were able to properly assess the damage.

Michael Efron, a senior forecaster from the Bureau of Meteorology (BOM), said that the Geelong was the worst hit area by the storm.

"(It) brought very intense rainfall in around half-an-hour to an hour and that resulted in flash flooding," Efron told Fairfax Media.

"Inverleigh, just west of Geelong had 37mm since 9 a.m. However, of that 30mm was in one hour when that storm went through between 6 p.m. and 7 p.m."

Though the storm had passed, rain continued to fall in Melbourne on Tuesday morning and it was expected to continue throughout the day.

The Country Fire Authority (CFA) warned people to remain cautious around the floodwater and to avoid driving in areas where the road was covered by water. Endit
