A minor to moderate flood warning has been issued for the Hunter River at Muswellbrook and Denman.
The State Emergency Service said minor flooding was expected at Scone and Muswellbrook early Thursday morning, with moderate flooding possible later Thursday morning.
Minor flooding is also possible at Denman Thursday afternoon.
It comes after heavy rainfall has been recorded across the Upper Hunter and Goulburn River catchments since Wednesday afternoon. Further storms are expected over the next few hours on Thursday.
Flows from the Goulburn River are expected to contribute to river level rises at Singleton and downstream from Friday.
Forecasts for locations downstream of Denman will be issued when upstream peaks are observed.
The Kingdon Ponds was expected to reach the minor flood level (3.20m) early on Thursday and rise through the morning to potentially cause moderate flooding.
The Hunter River at Muswellbrook was expected to exceed the minor flood level (7.20m) on Thursday morning and potentially reach the moderate flood level (8m) late Thursday morning.
The Hunter River at Denman may reach the minor flood level (6.50m) Thursday afternoon.
