A severe weather warning has been issued for much of southern and central NSW, as heavy downpours spark concerns of localised and flash flooding.
People on around 100 properties in Cooma remain on evacuation alert on Wednesday morning, with 150mm of rain expected to produce flash flooding across parts of the state, the Bureau of Meteorology (BoM) said.
Residents in the low-lying towns of Queanbeyan, near Canberra, and Goulburn are also being warned to prepare for flash flooding.
Overnight, heavy rain sparked more than 70 calls for help to the State Emergency Service (SES), as trees were brought down, roofs were damaged and properties were threatened with inundation.
In Tumut, near Wagga Wagga, 19 people were evacuated and five caravans at the local park were relocated, SES spokesperson Andrew Richards said.
Sandbagging around properties has begun in Cooma, as the SES monitors rainfall to see if evacuation might be necessary on Wednesday.
“At this stage the catchment is fairly saturated, and a significant downfall could change the current situation,’ Mr Richards told AAP on Wednesday.
He said the south had been relatively dry this summer, with flooding concentrating in the north of the state until the recent downpours and it looked like the south was now going to be hit with a lot of rainfall over the next four days.
“It is looking as if it’s going to be the area to keep an eye on over the next couple of days,” he said.
A flood watch is in place for valleys in the south of the state, with the BoM warning of a 70 per cent chance of flooding.
Areas predicted to be affected by minor to moderate flooding include the Hawkesbury Nepean, Queanbeyan, Molonglo, Murrumbidgee and Lachlan valleys and river systems.
Local flooding is also expected in the Lower Western district of the state south of Tibooburra, White Cliffs and Cobar during Tuesday and Wednesday, the BoM said.
