Much of Australia's east coast is in for a wet weekend that could develop into a 'powerful' weather system that will bring damaging winds and flooding to some areas.
Rain has already set in for much of NSW, southern Queensland and parts of Victoria. Up to 100mm of rain will soak some regions by Sunday, when a low pressure system will hit the NSW coast between Sydney and Port Macquarie.
'The coastal low will be dragging the cold wind over the coast,' the Bureau of Meteorology's Edward Medlock said.
He said the system would 'linger 'over the NSW coast for days.
'A big wad of cold air ends up sitting over the state, as that makes its approach to the coast and that low pressure starts developing over the ocean, it's going to become an extended period of prolonged rain.'
He said there is an 'intensity aspect' related to the weather system.
Bureau colleague Miriam Bradbury said the rain on Friday will be concentrated in south-east Queensland and pushing down into NSW.
'In Queensland we are going to see a gradual easing trend through Saturday afternoon and Sunday in particular, with a much dryer end to the weekend.
Drab weather in NSW is expected to continue into next week, with chances of heavy rainfall
Much of the country's east coast will have been soaked by Sunday
'But it is a different story for NSW where the wet weather is likely to continue into early next week with the new system on Sunday.'
The Bureau said there could be widespread rainfall totals of 50mm to 80mm over Monday. The Sydney, Hunter and Mid North Coast regions are expected to bear the brunt of it.
Gusty southerly winds will hit the coastal regions as stronger winds buffer the ranges and, by the end of next week, much of NSW is expected to have been drenched.
