Parts of NSW hit with devastating flooding a year ago are in for even worse this time around as the state's flood disaster continues.
How bad the flooding would be overnight depended on how much rain fell, rain brought by a low-pressure system that is finally moving off the coast and is expected to ease.
However, as the rain eases strong winds are set to follow, bringing further danger by threatening to topple trees and down powerlines.
The Hawkesbury River at North Richmond, in Sydney's north west, peaked at 14.13 metres around 12:15am, with major flooding slightly higher than the March 2021 event. The river level is currently at 14m and steady.
Downstream at Windsor the river may reach around 14.20m midday today, with major flooding. This level is above the March 2021 event and just below the 1978 flood.
In the NSW Hunter region, Bulga southwest of Singleton could see worse floods than last year on Wednesday morning, with major flooding likely to reach Singleton as well.
In the Northern Rivers, a fifth flood-recovery centre is set to open on Wednesday at Casino, joining others already operating at Mullumbimby, Murwillumbah, Kyogle and Lismore.
And further north and flood-hit southeast Queensland is bracing for more rain with severe thunderstorms forecast for Wednesday.
