Parts of Victoria have had a month of rain in less than a day, with emergency workers called to rescue two people from flash floods.
The Bureau of Meteorology’s Dean Narramore says it’s been the wettest day for a year.
“Victoria has copped a drenching in the last 24 hours,
“Many locations, not only in Melbourne but right across western and central Victoria, have had a month’s worth of rain in less than 6-12 hours,” he said.
The State Emergency Service has rescued a driver from a vehicle trapped in floodwaters in South Melbourne, and another from a vehicle in Bendigo.
About 70 SES units have responded to 400 calls for help in the past 24 hours, mostly for leaking roofs and other storm damage.
For Melbourne, which has a monthly average rainfall of 47mm, parts of the city have seen up to 50mm in the space of a few hours.
The Grampians in the state’s west has copped the heaviest falls so far, with 68mm of rain at Mt William.
Flood watches are in place for the Avoca and Campaspe rivers, but there are no reports yet of major rivers bursting their banks.
SES operations manager Josh Gamble is warning residents in flood-prone areas to monitor the conditions, and either leave the area early, or be ready with sandbags should the waters rise.
“We know flash flooding comes up out of nowhere, so we can’t plan for where it may impact,” he said.
Mr Gamble also urged motorists not to drive through floodwaters, saying it takes only 15 centimetres of water on a road for a vehicle to float.
The weather system causing the rain is still in the west of the state and moving slowly east, so there is much more rain to come.
Mr Narramore says conditions may not ease until early to mid-morning on Saturday.
“Flooding and flash flooding is definitely going to become an issue in the coming days and weeks,” he says.
More storms are predicted for eastern Victoria on Friday night.
