The weather system is now shifting towards a “melt down” and will bring significant rain and flash flooding across parts of New South Wales, according to the Australian Bureau of Meteorology (ABC).
Key points:More than 40% of South Australia will experience flash flooding in the next 24 hours after the severe weather system hitsThe state is already facing one of the worst floods in its history with more than 1,000 people needing emergency services to reach homesA ‘mashup’ of the weather system could bring up to 1,500 millimetres of rain and as much as a foot of rainfall in the state of South Australian by Saturday night and into Sunday morning.
“It is the most powerful storm system that has ever passed over Australia, the strongest in the history of Australia, with more rain, more mud and potentially more flash flooding,” Environment Minister David Healy said on Tuesday.
The system is moving away from the Great Australian Bight towards the state’s southern coastal regions, with heavy rain and strong winds expected across the state.
The state’s weather bureau said the system is expected to bring up-to-1,500 mm of rain over parts of the southern coastal areas of South and South-West Australia.
“There will be significant flooding from the south-west of South South Australia,” Environment Bureau chief Paul Kennedy said.
“The system will be moving away towards the coast, the rain will be very heavy and there is potential for flash flooding.”
We’ve had rain showers in the area over the past two days and we’ve had flash floods.
“It is forecast the system will move north into Western Australia, then onto Queensland and then into the state by Sunday morning.”
The system was expected to move across the Great Barrier Reef by Saturday afternoon and would be moving north through the state as it moved through South Australia.
South Australia is already suffering one of its worst floods of the century, with up to one in five homes without water.
In a statement on Monday night, South Australian Premier Jay Weatherill said he was “very concerned” about the impact the weather would have on the state and the country.
“This storm is likely to be a bit of a mosh-up, so the worst that’s likely to happen is the rain,” he said.
Mr Weatherill also confirmed the state was already facing a severe water shortage and had to deal with a “severe” water crisis.
“South Australia has a severe drought, so we have a severe shortage of water,” he told ABC Radio Adelaide.
“If you’re a South Australian household that’s going to be very affected by this weather system.”
