Severe thunderstorms are expected across New South Wales and may bring widespread moderate rainfall from Wednesday and into the weekend.
The Bureau of Meteorology (BoM) said severe thunderstorms are possible for north-eastern New South Wales over the coming days, including the New England North West.
The BoM has also issued a Flood Watch, noting minor flooding may occur from Thursday along the Upper Macintyre (Severn), Bellinger and Kalang and Nambucca rivers.
The NSW Incident Alerts have put out a rain map for the coming days, and says while the conditions have been difficult to pin down, areas like Inverell, Ashford, Tenterfield, Glen Innes and Armidale could see up to 100 mms of rain, with Moree anywhere from 30 to 50 mms.
"A slow-moving upper trough interacting with moisture-laden air will allow storms and rain to develop through Wednesday and Thursday," a NSW Incident Alert spokesperson said.
"This wet weather pattern will continue to linger through the weekend and even into next week, potentially fueling a week-long rain event."
Landslips and fallen trees are also possible due to recent flooding. Localised heavy rain, gusty winds and hail are all possible.
With catchments remaining saturated from recent rainfall events, there is an increased risk of flash flooding and renewed river rises. This is particularly true for areas of the Hunter, Mid North Coast and Northern Rivers.
Water from inland Queensland is still moving south into northern New South Wales along the Birrie, Bokhara and Narran rivers. Along the Narran River, moderate flooding is currently occurring at Angledool.
This may reach major flood levels on the weekend.
Communities should be prepared for flood impacts and are encouraged to keep up to date with the latest forecasts and warnings on the Bureau's website and BOM Weather app, and to follow the advice of emergency services.
