Peel River peaked above moderate flood level in Tamworth; Namoi River could reach major flood level in Gunnedah on Tuesday and Wednesday

Residents have been told to prepare after heavy rain early in the week fell on already soaking catchments and swollen rivers.

"Flows from the Namoi and Mooki rivers may cause major flooding and a prolonged flood peak at Gunnedah from overnight Tuesday into Wednesday," the NSW State Emergency Service (SES) warned.

Low-lying roads, bridges, rural areas and places along the Namoi River may be affected, based off Bureau of Meteorology predictions.

The latest warning on Tuesday afternoon said the river may peak close to the major flood level of 7.9m in Gunnedah later tonight or on Wednesday morning.

The warning comes not quite two weeks after the last major flood swept through the small town west of Tamworth, and just three weeks after the last major flood before that hit.

Wee Waa has also been told to brace for further flooding.

"Local tributary inflows have caused initial rises and minor flooding at Wee Waa, where the main flood peak from the Namoi River is forecast to arrive at Wee Waa towards the end of the week," the SES said.

No evacuation orders had been issued by 5pm on Tuesday.

Residents have been reminded to never enter floodwater as dozens of roads across the region remain closed, including O'Briens Lane and Warral Road in Tamworth, plus more.

Flood advice:

Call the SES on 132500 for help, call triple zero in a life-threatening emergency.

More warnings and updates can be found on the SES website.

ROADS have opened across Tamworth as floodwaters move downstream towards Gunnedah.

Gunnedah is bracing for what could be its seventh flood - or its sixth major flood - in the past 12 months.

The Bureau of Meteorology (BOM) has warned major flooding is possible at Gunnedah and Wee Waa, as well as minor flooding at Boggabri and Narrabri.

The Namoi River at Gunnedah could hit the moderate flood level of 7.6m this evening and the river may peak near the major flood level of 7.9m overnight and into Wednesday, the BOM warned on Tuesday afternoon.

Further rises are possible at all of those locations, according to the BOM.

FLOODWATERS are receding across Tamworth, allowing some roads to reopen.

Scott Road and Manilla Road reopened overnight after being submerged on Monday afternoon.

Calala Lane and Ebsworth Street had already reopened earlier in the evening.

Jewry Street was still closed on Monday morning, making the work commute a little busier for those trying to get into town via Bridge Street.

Dozens of roads across the region remain shut off to all traffic as council crews inspect them.
