Moderate flooding is also possible at Narrabri overnight on Friday and into Saturday, according to the BOM.

The Namoi River at Boggabri may reach around 8.10 metres on Friday morning.

Meanwhile, some of the key roads in the region have started to reopen, including the Oxley Highway from Gunnedah to Carroll.

The Kamilaroi Highway has also reopened.

GUNNEDAH is in the midst of its fourth major flood in two months, with the Namoi River expected to peak this morning after residents were evacuated last night due to "dangerous" flooding.

The Bureau of Meteorology (BOM) is expecting the Namoi to peak this morning at 8.40 metres, a similar height to last week's flood event. It's currently above 8.2 metres and rising.

An evacuation centre has been set up at the Gunnedah showground.

The Namoir River at Boggabri may exceed the minor flood level this morning, and could reach around 8.20 metres Thursday evening with minor flooding, according to the BOM.
