Senior meteorologist<\/a> David Crock said the system is currently producing plenty of rain and storms through the deserts of eastern Western Australia and western South Australia, before it\u2019s forecast to impact parts of southern Northern Territory later on Sunday, including parts of Alice Springs.<\/p>\n Know the news with the 7NEWS app: Download today Arrow<\/a><\/p>\n As the system moves east it will impact multiple states over several days, causing downpours, storms and possible flash flooding. <\/p>\n \u201cIt\u2019s a pretty big system which is drawing in moisture from the Indian Ocean,\u201d Crock said.
<\/p>\n \u201cSo it\u2019s going to bring quite a bit of rain, basically to every state and territory over the next three days or so.\u201d<\/p>\n South Australia<\/p>\n Crock said the focus on Monday is very much South Australia, with the low pressure system tracking along the coastline, bringing rain to most of the state as well as storms.
<\/p>\n \u201cThe centre of the low pressure system itself, potentially probably the highest impact for South Australia tomorrow, will be over the Eyre Peninsula and the Yorke Peninsula and then towards Adelaide<\/a> and the Hills late tomorrow,\u201d Crock said.<\/p>\n Rain bands could produce between 30mm to 50mm across parts of South Australia through Monday and into early Tuesday morning.<\/p>\n \u201cThose areas are quite wet already. They\u2019ve had quite a bit of rain in recent weeks and months,\u201d he said.
<\/p>\n \u201cSo impact from that could be some pretty quick flash flooding and quite a bit of rain lying around on the ground for a while there.\u201d<\/p>\n VIC, NSW, QLD<\/p>\n The system is then expected to move eastward towards Victoria<\/a>, New South Wales and southern Queensland late on Monday, with wild weather in the eastern states ramping up on Tuesday.<\/p>\n Crock said parts of VIC could see 40mm to 60mm of rain or more during Tuesday, with concerns on areas of Northern VIC from previous rain events, with more flood warnings likely.
<\/p>\n \u201c(The rain) will put plenty more water in those river systems that flow into the Murray,\u201d he said.
<\/p>\n \u201cThere\u2019s kind of rain across pretty much all of Victoria on Tuesday.\u201d
<\/p>\n The System will bring a risk of severe thunderstorms during Tuesday through northern VIC, much of western NSW and even up into southern Queensland.
<\/p>\n \u201cSevere thunderstorms which could bring particularly heavy rain, but then also damaging winds as you head through that north as well,\u201d Crock said.
<\/p>\n By Wednesday the low pressure system will move out into the Tasman Sea, but continue to bring plenty of rain and storms to parts of the eastern half of NSW and up into southern and south-east Queensland.
