Up to 300 millimetres of rain has fallen since Wednesday morning in the lower Gwydir Valley.
Rain has eased since 9am this morning but the Bureau of Meteorology reported thas rain of 50 to 60 millimetres fell in less than seven hours earlier today.
At the predicted flood levels, lowland farming areas will be impacted with overland flood water and pumps and livestock should be moved to higher ground.
In Moree Plains Shire the “Biniguy Break” may occur at Biniguy, crossing the Gwydir Highway and directing floodwaters onto farmland overland to the north and west of the village and eventually into the Mehi River.

Access to Pallamallawa may be restricted from the Gwydir Highway at Long Creek and residents should monitor rises in the Gwydir River and localised flooding from the rain and prepare for predicted major flooding.
At the predicted flood height, residents in low-lying areas along the Gwydir River at Yarraman should move pumps and livestock to higher ground and monitor river heights for sudden rises and prepare for predicted major flooding tomorrow morning.
Residents in the Stonnington Lane and Chinamans Lane areas of Moree should also prepare for predicted major flooding tomorrow.
This flood warning means that people living or working along rivers and streams must monitor the latest weather forecasts and warnings and be ready to move to higher ground should flooding develop.
This is especially important for people living, camping or working along the Gwydir and Mehi Rivers and streams in the Gwydir Valley and adjoining rural areas.
Local roads may close and driving conditions could become dangerous. Creeks and streams may break their banks placing livestock and equipment in low-lying paddocks at risk.
If flooding occurs:
- Farmers should move livestock, pumps and farm equipment to higher ground.
- Campers should note how close creeks and rivers are to their campsite; organise campsites so they can be quickly relocated; and stay in touch with fellow campers.
- Don’t walk or drive through floodwater: it may be deeper and faster flowing than you realise.
- Stay away from storm drains, creeks and rivers.
