Pictures and videos shared to social media showed flooded streets and inundated walkways.
‘Flinders street is like Venice,’ one person wrote on Twitter with a video of the conditions.

Metro Trains have tweeted a number of updates and urge commuters to ‘consider the use of alternative transport’.
Train services at Alamein, Belgrave, Glen Waverly and Lilydale have been impacted.
The Bureau of Meteorology tweeted: ‘SEVERE THUNDERSTORM WARNING for the #Melbourne metropolitan area. Activity heading southwest through the western suburbs towards #Geelong with heavy rainfall.’
The severe thunderstorm warning says heavy rain is anticipated.
Sydney was also lashed with another thunderstorm on Friday afternoon causing traffic and travel delays.
The Bureau of Meteorology released a severe thunderstorm warning for Sydney and Newcastle on Friday night with the possibility of giant hailstones, torrential rain and rampaging winds hitting the coast – as the country’s north braces for a category four cyclone.
Sydney’s airport has gone into lockdown, with all services suspended for the time being due to the wild weather.
More than 30 flights have been cancelled at Sydney Airport.

Sydney also got a brief downpour, with 40mm of rain falling in less than half an hour
Bureau of Meteorology forecaster Jordan Notara said the storm travelled through Sydney at about 4pm on Friday.
‘Those storms were mostly in the west, but we did see some strikes on the coast,’ he told Daily Mail Australia.
Mr Notara said there was still a severe thunderstorm warning which could continue into the evening.
‘There is still a threat into the evening,’ he said.
Mr Notara recommended to check weather updates amid the temperamental conditions.
Travellers are urged to contact their airlines about cancellations and delays due to the weather.

The conditions have also had an impact on Sydney’s roads and public transport services.
Trains between Hornsby, Gosford, the Central Coast and Newcastle have been cancelled due failing signals brought on by the weather.
‘Trains are currently suspended between Hornsby and Gosford in both directions due to urgent power supply repairs affecting signals as a result of severe weather conditions,’ NSW TrainLink North Tweeted on Friday afternoon.
‘Please delay travel if possible. If you need any travel assistance please let us know.’
Commuters were forced to line for packed buses due to the cancellations.
A single-vehicle crash on the Sydney Harbour Bridge is causing traffic chaos across the city.
The crash occurred when a Mitsubishi Mirage hit a stationary vehicle on the bridge at about 4.45pm.
The driver refused to undertake a breath test and has been arrested.
Two children, a three-year-old girl and a five-year-old boy, were in the vehicle at the time of the crash and are being assessed for possible minor injuries.
The Bureau of Meteorology is warning residents to prepare to ‘batten down the hatches’
Severe thunderstorms and heavy rain could hit the New South Wales coastline and go as far inland as Orange and Tamworth, about 250km from the coast.
The New South Wales State Emergency Services have advised residents to use sandbags under their doors to help keep flood waters from leaking into their homes.
The Bureau of Meteorology shared the sentiment, warning people to ‘be prepared to batten down the hatches’.
Mr Notara said the rainfall was not as strong as what was recorded on Thursday evening when Sydney braced another storm.
Most rainfall was recorded in Sydney’s west on Friday with between 20-30mm recorded from 9am.

The Bureau said about 10mm was recorded on the coast.
On Thursday night, 40mm of rain fell in less than half an hour.
Winds of up to 107km/h whipped through the city’s western suburbs on Thursday night, as nearly 700 calls for help were made to emergency services.
A further 30,000 homes and businesses were left without power in the quickfire storm.
But that could just be a sign of what’s to come for Friday, with more lightning, hailstorms and wild winds forecast to rampage through the state on Saturday.
Victoria also felt the pinch of the wild weather on Thursday, with more than 100 people needing to be rescued from semi-submerged cars on the Hume Freeway.

Melbourne’s inner-city flooded, with pedestrians forced to wade through the high waters
Another month’s rainfall could come down on Friday, with a further 20mm forecast in the morning
More than a month’s worth of rain fell in regional areas overnight.
The average December rainfall for Melbourne is 59mm, with the city already surpassing that on Thursday and another 20mm forecast for Friday.
The rural town of Everton had 162mm fall overnight on Thursday alone.
Meanwhile, 20 homes flooded in the Central Victorian area of Birchip with 10 people evacuated. A community meeting will be held on Friday to discuss further flooding procedures, the SES say.
‘It’s like an ocean here where we are at the moment, our whole street is under water,’ one resident told 3AW radio on Friday morning.
Periods of heavy rainfall led to flash flooding in both Sydney and Melbourne on Friday

A severe weather warning was issued for Victoria with heavy rainfall across the entire state
Thunderstorms on Thursday night (pictured) will continue on Friday, forecasters warn
The overnight rainfall continues on Friday, with the worst storms forecast to fall in the state’s east, predominantly the South Gippsland area.
‘Rain and thunderstorms are expected across the warning area during today and Friday, with periods of heavy rainfall likely that may lead to flash flooding,’ a warning issued by The Bureau of Meteorology reads.
Authorities continue to warn not to drive or even walk through flood waters, after dozens of cars and trucks were submerged in the flood waters.
Torrential rains, particularly in New South Wales, are linked to a tropical cyclone brewing in the country’s north.
Meanwhile, a category three cyclone could hit far-north Queensland on late Friday afternoon
The cyclone is currently off the coast of the Northern Territory, and is slowly heading east
Cairns and the rest of far-north Queensland are meanwhile bracing for Tropical Cyclone Owen, with meteorologists saying it could hit either Friday or Saturday.
WHAT IS A CATEGORY THREE CYCLONE?
Tropical cyclones are categorised on a scale of one to five based on severity.
TC Owen, which is expected to hit Queensland on Friday, is classed as a category three.
A category three cyclone would cause:
– Some roof and structural damage. Some caravans destroyed. Power failures likely.
– A category three cyclone’s strongest winds are very destructive winds with typical gusts over open flat land of 165-224kph.
However, the cyclone could be re-classified once it actually hits land, which will be either Friday or Saturday.

As of Friday morning, the cyclone is tracking off the coast of the Northern Territory, but has begun to move east and could hit Queensland as soon as midday.
The cyclone is currently classed as a category three based on its 200km/h wind speed.
But forecasters say it could become a category four, surpassing 280km/h when it crosses the Gulf of Carpentaria and into Queensland.
A cyclone warning is in place from Port McArthur in the Northern Territory, to Aurukun in Queensland.
Residents are being told to brace for wild winds and flooding.
Some are concerned that floods will cause landslides, after wild bushfires rampaged through the state, leaving some regions’ hillsides unstable.
Premier Annastacia Palaszczuk said she’d been briefed on the danger and assured Queenslanders that authorities in the cyclone danger area are well prepared.
The devastating cyclone, which is deemed as ‘very destructive’ by the Bureau of Meteorology, is a result of a coinciding mass air movement and low pressure system.
Some areas of Victoria recorded as much as 162mm of rain in less than 12 hours on Thursday
‘It’s being caused by a trough of air mass movement from the north, and with a low pressure system coming through, is generating large amounts of rainfall,’ Bureau of Meteorology forecaster Peter Newham told Daily Mail Australia on Thursday.
A Bureau of Meteorology forecaster previously told Daily Mail Australia the thunderstorms would be the result of a cold front in the south of the country.
The cold front and low-pressure system moved from Victoria up to New South Wales which brought showers and a storm to Sydney on Thursday night.
Canberra can also expect storms and upwards of 55mm of rain between Thursday and Saturday.
Brisbane was also predicted to get up to 100mm of rainfall over the weekend.
