Southern Victoria has been smashed by heavy downpours overnight as a cold front pushes north to bring rain and storms along the NSW coast.
Coastal Victoria has been smashed by more rain in the past 24 hours than some parts of the state in the past six months as a cold snap crosses southeast Australia.
Persistent rain set in across southern Victoria on Monday evening and continued throughout the night, with Aireys Inlet on the Surf Coast recording a torrential 116mm.
That’s more rain than Swan Hill – in Victoria’s northwest – has seen in the past six months with only 67.2mm recorded there since the start of November.
Melbourne has recorded 31mm in the past 24 hours, while Laverton and Avalon in the city’s west saw 42mm and 38mm.
It comes as temperatures plummet across the nation’s southeast this week, with significant rainfall returning to snap the warm run of weather from the weekend.
Weather bureau senior forecaster Matthew Thomas said southern and eastern Victoria would receive between 20-40mm of rain on Tuesday, with isolated falls of 60mm in some areas across an 18-hour period.
“It’s possible that we could see flash flooding, we will be monitoring the situation and if necessary we will put out a severe weather warning for heavy rainfall,” Mr Thomas said.
The rain is expected to ease in Melbourne by Wednesday as the cold front pushes further north towards NSW.
Gippsland is expected to receive about 20mm on Wednesday, while the eastern ranges could see between 60-90mm.
Sydney is forecast to receive up to 10mm on Tuesday and 20mm on Wednesday, with the chance of a thunderstorm in the morning and afternoon.
Sky News Weather meteorologist Rob Sharpe said it would be “soggy” conditions due to a low pressure trough.
“Showers and even the odd thunderstorm will march through NSW during the day on Tuesday,” he said.
“So for Sydney and surrounds, instead of the smoke and fog, we’ll see the wet weather coming down from above.
“That wet weather continues on Wednesday, with showers for the coastal regions (of NSW), and showers and the odd storm up further north, maybe for Brisbane on Wednesday as well.”
On Thursday, the wet weather will return to Victoria, especially around the border region of Gippsland and the southeast coast of NSW.
Mr Sharpe said much of the NSW coast would see 25-50mm this week.
He said tropical moisture is also “streaming down” the west coast of the nation bringing a big rain event for Western Australia on Tuesday and Wednesday, with “substantial” totals of 25-50mm for much of the southwest of the state.
