AS flooding continues across central and south-western Queensland, communities across far north-western and central-western New South Wales have been issued stay informed advice and flood watch alerts.

Walgett and Lightning Ridge has received more than 100mm of rain since 9am, Friday, with falls of up to 90mm in the Collarenebri district.

There is Stay Informed advice for Boggabilla, Toomelah and surrounding areas.

This weather system has the potential to cause minor flooding in the Flood Watch into the weekend.

The Bureau says a low pressure system in western Queensland has extended across the northern interior of New South Wales.

The system has tracked across eastern New South Wales, with widespread rain occurring.

The Gunnedah, Boggabri and Tamworth districts have received up to 50mm of rain since 9am, Friday, with about 30mm falling across Upper Horton, Barraba and Bingara, and upwards of 40mm for the past seven days.

Moderate to heavy rainfall is expected in parts of western and central inland New South Wales across the weekend, with more falls predicted for the middle of next week.

On Saturday the rain is expected to spread east, covering a large part of the state.

Widespread totals of 25-50mm are expected, with isolated higher falls of 100mm possible.

From Sunday, severe weather will largely be restricted to the south coast, with rain, damaging winds and large surf expected, increasing risks of flash-flooding, falling trees and coastal erosion.

NSW SES Assistant Commissioner Dean Storey said the main risk associated with the widespread rain was flash flooding.

“We may see water levels rise quicker than normal, particularly where the ground is already saturated as a result of Ex Tropical Cyclone Alfred,” Mr Storey said.

“We may see roads cut by water which is unable to drain away. You should never drive through flood waters”.

The NSW SES has issued a Watch and Act flood warning for residents at Thora to prepare for isolation. Meanwhile minor flooding is possible this weekend in parts of the Northern Rivers including the Wilsons, Tweed, Brunswick, Richmond and Orara Rivers.

There is also a flood warning for the Paroo River in North Western New South Wales.

Mr Storey said the NSW SES had prepositioned rescue assets including high clearance vehicles, flood rescue teams and helicopters at higher-risk locations.

“The public are advised to monitor the conditions and download the Hazards Near Me App to stay up to date with the latest information and warnings,” he said.
