As NSW endures another flooding emergency, authorities warn people in Sydney, Hunter, Illawarra and several other areas to prepare for another day of wild weather.
Hundreds of people have been forced to flee their homes across Greater Sydney, with 69 evacuation orders in place.
NSW State Emergency Service SES spokesman Adam Jones said crews performed 18 rescues overnight as persistent heavy rain continues to bucket down and the Hawkesbury, Nepean and Colo rivers flooded.
The Bureau of Meteorology BoM forecasts up to 120 mm of rain in the Harbour City today, although the east coast low that caused the deluge has weakened.
Greater Sydney residents have been warned to avoid travel and check the SES website for evacuation orders.
The SES has conducted 111 flood rescues with more than three-thousand calls for help since the emergency began.
It's the third time this year that many of the areas that are inundated, including parts of Sydney's north west and south west, have been flooded.
The downpour became deadly yesterday when a man drowned in the Parramatta River in Abbotsford yesterday afternoon.
SES Assistant Commissioner Sean Kearns said people in Greater Sydney should be vigilant.
He said that as the east coast lows inland tomorrow, we are warning people that we are expecting to see rainfall in the Hunter area.
We might see river rises in the Hunter and communities being impacted.
