Brace for IMPACT: Nearly ALL of Australia to be Hammered by a Mega Rain Bomb – Here’s When the Wild Weather will Hit Your City

By Olivia Day

Virtually all of Australia will be lashed with relentless rain this week as the east coast braces for dangerous storms and record-breaking falls.

Sydney is expected to receive up to 100mm of rain over the coming days as forecasters warn the deluge will trigger even more flooding across the state.

Most of New South Wales, southern Queensland and northern parts of Victoria are expected to cop the brunt of the ‘double whammy’ weather events.

The East Coast will receive its first battering on Wednesday, with the wet weather to persist well into the weekend following the arrival of several cold fronts.

Forecasters say a ‘significant’ rain band is heading to the east coast from central Australia to bring misery to South Australia, Victoria, NSW and Queensland.

Weatherzone’s Andrew Schmidt told Daily Mail Australia the system would bring on-and-off rain to most parts of the country this week and next.

Two troughs currently sitting over the Top End and South Australia are due to combine on Wednesday and deliver up to 80 to 120mm of rain to the east coast.

‘Sydney is in the firing line for some pretty heavy showers,’ Mr Schmidt said, adding that Sunday is set to be the wettest day in the Harbour City this week.

The forecaster said the rain would trigger renewed riverine flooding in NSW’s regional areas that have had little time to dry out after the downpours last month.

Additionally, northern Tasmania would receive some relatively heavy falls, with Devonport to receive up to 35 to 65mm on Thursday and Friday.

The Bureau of Meteorology’s Jonathon How said widespread rain across eastern Australia would increase the risk of floods in already saturated areas.

Mr How said the rain would impact most of Australia over the next seven days, with falls stretching from the Top End all the way to the eastern interior.

By Friday, southern and inland Queensland, NSW, and northern parts of Victoria could see isolated falls of up to 50mm, the forecaster said.

‘Catchments are wet, and rivers will respond very quickly,’ he said.

On Tuesday, showers and storms will hit the Northern Territory and Adelaide, with rain to worsen in western Queensland, NSW and northwest Victoria.

On Wednesday, heavy falls are forecast to hit parts of the east coast with the addition of a gusty easterly wind along the southern coastline.

NSW SES Chief Superintendent Dallas Burnes said he was most concerned about saturated inland areas like Gunnedah, Wee Waa, Wogga and Albury.

He said the SES had deployed flood rescue teams to those areas with four people rescued from a car in Griffith, in the state’s Riverina region, overnight.

Brisbane will remain relatively dry, with 10mm of rain falling between Wednesday and Sunday. However, southern parts of the sunshine state, including Thargomindah and Cunnamulla, will be lashed with up to 50mm of rain on Tuesday and Wednesday.

Bourke, in NSW’s northwest, will receive from 45 to 60mm of rain on Wednesday, while Dubbo will receive up to 20mm.

The rain is set to linger in NSW’s inland areas for several days. By Sunday, Bourke could receive up to 120mm of rain, Dubbo 100mm and Tamworth 60mm.

On Friday, another trough and connected cold front will cause showers to linger into the weekend in western and central Queensland, most of NSW and northern Victoria.

Tasmania will experience storms on Thursday, with a low pressure system to ‘drag’ further showers and rain to Sydney and Brisbane over the weekend.

On the east coast, temperatures will remain below average for October and will struggle to make it past the low 20s this week and next.

Record-breaking rain fell in the town of Derby in the Northern Territory on Sunday, with 55.6mm falling in the 24 hours to 9am – the highest daily total for the month of October in 62 years of records.

Curtin, in Alice Springs, hit triple digits with a record 103.2mm falling in the same period – the most rain the region has received in nearly three decades.

Canberra could be lashed with up to 30mm of rain on Wednesday with temperatures to linger in the late teens with highs of just 19C this week.

Adelaide will remain wet with scattered showers forecast to start from Wednesday and temperatures to remain in the low 20s.

Hobart will dodge a lot of the heavy rain with the northern coast to receive the brunt of the wet weather, with 35 to 65mm forecast to fall over Devonport on Thursday.

A cold southerly wind will cause temperatures to plummet to -12 at night.
