People around the state still picking up the pieces from recent flood events are now facing the prospect of having to leave their homes yet again, and watch their businesses go under.
A Severe Weather Warning remains in place for metropolitan Sydney, along with the South Coast, Hunter region and the Central and Southern Tablelands.
Up to 100mm is set to fall while 140mm could fall in the coastal regions.
Multiple flood warnings remain in place across NSW, including in the Hawkesbury region and along the Georges River, where flooding damaged homes and cut off communities just weeks ago.
An evacuation warning is also issued for parts of Woronora and Bonnet Bay in the Sutherland Shire, with residents urged to prepare to evacuate.

There are major concerns for catchments in the city's north-west and Hawkesbury Nepean, where the dams are full which could cause flooding.
Warragamba Dam, which is currently at 100 per cent capacity, is set to spill on Friday due to the incoming rain bomb.
The new rain "is not expected to produce riverine flooding instead it will be more localised flash flooding," meteorologist Sarah Scully said.
Chloe Konispoliatis, from McGraths Hill in Sydney's north-west, said she was "terrified" to see the rain return, fearing her home could be flooded for a third time in less than two years.
"We have only just started to get our life back together," she told Today.
"We managed to clean quite quickly this time around, because we, unfortunately, were impacted by the floods last year as well.
"This year we were a bit more prepared."
In the recently-ravaged Northern Rivers region, Wardell woman Rebecca Heywood is also facing another round of heavy rain, after her cottage was damaged by floods last month.
"I don't think our communities can take much more," she said.
