Melbourne residents suffering through a crippling Stage Four COVID-19 lockdown have been hit with further misery after a ferocious storm caused widespread blackouts and 250,000 people were left without a clean water supply.

Three people were killed overnight, including a four-year-old boy, after the storm tore into the Victorian capital – bringing wind gusts as strong as 124km/h.

There were still about 50,000 homes without power on Friday morning, with the State Emergency Service receiving 1700 calls for help throughout the night. 

A quarter of a million residents in Melbourne have meanwhile been told to boil their water after Yarra Valley Water issued a contamination warning on Friday to 88 suburbs including Attwood, Templestow and Fawkner.

Residents have been told they could experience gastro-like symptoms if they drink the water or use it to prepare food without boiling it first. 

Contamination fears led to bottled water being stripped from supermarket shelves as Melbournians bought the product in bulk on Friday.

The warning followed non-disinfected water leaving Silvan Dam and entering the city’s water system.

Residents in Australia’s second most populated city reacted angrily to the additional hardship of the water supply issues.

‘Only allowed one hour of exercise, one hour of sunlight, now have to boil water, as it’s contaminated! What a liveable city this state has become,’ one person wrote.

‘No power or non contaminated water within 5km from home. What are people supposed to do?’ another said.

Meteorologists are predicting a calmer weekend of weather in Melbourne with westerly winds up to 20 km/h on Friday becoming light in the middle of the day and then becoming north to northwesterly 15 to 20 km/h in the late evening. 

Little Ayan Kapoor was one of three people killed overnight by falling trees after a ferocious storm tore through Melbourne.

He died in hospital after being hit by a tree in Blackburn South in the city’s east at about 6pm on Thursday.

He was taken to Box Hill Hospital in a critical condition and then transferred to the  Royal Children’s Hospital, where he died later that evening.

The little boy had been out walking with his dad and little sister at the time of the tragedy, his family told Daily Mail Australia on Friday.

Ayan’s uncle Munish Chawla said his brother-in-law had just taken his two children out for a walk when the tree fell.  

‘It’s very sad. The parents are upstairs. They are in a very bad condition,’ the uncle said.  

SES personel assess property damage in Belgrave on Friday. Volunteers worked through the night to try to clear the fallen trees and branches littered across roads and railway tracks.

He said Ayan’s family on Friday morning were in a state of shock and too distraught to venture outside the house.  

‘He was with father and sister. They were altogether and just they’d just left from the home minutes earlier on their daily exercise,’ Mr Chawla said.

‘They just go out to the end of the road and then come back every day. That’s it.’ 

The large tree that claimed Ayan’s short life was among the tallest on the road, but neighbours said it showed no signs of toppling over.

Ayan’s uncle said the youngster had been enjoying kindergarten and looking forward to school. 

As workers removed the tree on the back of a truck, a teenage girl walking her dog appeared with a bunch of flowers.

She did not know Ayan, but was compelled to come and pay her respects. 

‘It’s just so sad. The poor little boy,’ she said. ‘The storm just came up out of nowhere.’

Workers on Friday continued to work to remove the tree from where it fell in Blackburn South. A 36-year-old woman who was a passenger in a ute was also killed by a falling tree

A spokesman for Whitehorse City Council said the council had received dozens of calls itself about damage to trees and fences.

‘The safety of residents will be our top priority as we attend to clean-up efforts and fallen branches across the municipality,’ the spokesman said.

A 59-year-old man also died after a tree crushed his car. He had been in a shopping centre carpark in Belgrave. 

A 36-year-old woman, who was a passenger in a ute driving along the Maroondah Highway at Fernshaw, was also killed by a falling tree at 6.50pm. The driver suffered minor injuries.

Multiple suburbs across the city were plunged into darkness during the deadly storm which tore through the state on Thursday night.
