Flood levels in the Hunter Region are yet to peak after heavy rain caused rivers to rise, amid strong winds and cooler temperatures.
A flood warning was in place on Sunday for the Hunter River and Wollombi Brook, with flood peaks expected on Monday and Tuesday.
Southerly winds brought gusts of 63 kmh at Nobbys on Sunday morning and a high of 15 degrees. Nobbys recorded a high of 25 degrees on Saturday.
The NSW SES advised people not to enter floodwater that was "fast moving" at the Melville Ford Bridge at Aberglasslyn. The bridge had to be closed.
The SES responded to 13 flood rescues across the Hunter and Central Coast, mostly vehicles in floodwater, while the Bureau of Meteorology reported mostly minor flooding.
"The Hunter River at Maitland (Belmore Bridge) may exceed the minor flood level (5.9 metres) on Monday afternoon. A minor flood peak may occur late Tuesday," a bureau statement said.
"The Hunter River at Singleton may exceed the minor flood level (10 metres) on Monday morning. The river level may peak near 10.8 metres on Monday evening."

Flood levels in the Upper Hunter, Paterson and Williams rivers were "generally easing or approaching below minor peaks".
