The State Emergency Service is urging Hunter motorists to look out for possible flooding across roads around Singleton and Bulga today, as rivers in the region continue to rise.
A minor flood warning has been issued for the Hunter River at Singleton which is expected to peak at 10 metres this morning.
The Wollombi Brook at Bulga is expected to peak at 3.7 metres at midday.
SES spokesman Ken Speer says locals should be prepared.
"Some low lying rural areas may be flooded and rural roads may be closed if the river continues to rise," he said.
"Land owners and farmers adjacent to the rivers should look at monitoring that situation and move their livestock, pumps and equipment if it's necessary to do so."
There is also a warning for flooding at the Belmore Bridge at Maitland this afternoon.
