Emergency services are monitoring the Hunter's major waterways as floodwaters start to flow through the region.
A minor flood peak is expected at Maitland at about 3:00pm (AEDT) on Tuesday afternoon (tomorrow) and the Hunter River at Singleton will peak below minor flood levels later today.
There has been major flooding of Wollombi Brook at Bulga, which has reached a peak of more than five metres.
Flooding cut off all access to the village of Wollombi on Saturday and the owner of Wollombi Tavern Brenda Walsh says it brought back memories of the June 2007 floods.
"A little bit too close to the tavern for my comfort," she said.
"We had a really huge flood here in 2007 so this was getting up there."
"Not quite into our downstairs area where all our equipment is, so we were very very lucky to escape this time."
SES region controller Greg Perry says there are currently about 15 outstanding jobs around the Hunter, mainly for fallen trees.
He says more rain is forecast and that could cause problems.
"We're gearing up for a little bit more rain towards the end of the week," he said.
"We're looking at somewhere between 25 and 50 mils, the bureau are saying we could have some thunderstorms coming which might give us some heavier falls, somewhere between 50 and 100 mils, but it's all unknown at this stage.
"The ground is pretty sodden at the moment, so what we'll be doing in the next couple of days is making sure the volunteers are fully rested to get through this one and prepare for Thursday/Friday and see what happens."
