Urgent warning as THREE Aussie states hit with flash flooding

Heavy widespread rain has led to dangerous flash flooding across much of NSW as more people are told to evacuate from rising waters that have left some towns isolated.

In the 24 hours to Monday morning, the NSW State Emergency Service responded to 33 flood rescues and 462 requests for help.

The SES said a rescue was under way for a man trapped in his car in the central-western town of Alectown who called for help just before 4am on Monday.

Police and Rural Fire Service personnel have spotted the vehicle and a helicopter has been deployed to help rescue the man.

Meanwhile, people in low-lying parts of the central-western town of Canowindra have been urged to evacuate immediately because of high river levels and dangerous flash flooding.

An evacuation centre has opened at the local public school after the town recorded 99mm of rain in just six hours overnight.

The historic town of Molong, in the Central Tablelands near Orange, is completely isolated by floodwaters, with flash flooding making it too dangerous to evacuate.

The SES is warning people in Molong's low-lying areas to move to higher ground.

An evacuation centre has been opened at the RSL club, while an ADF helicopter has been sent to help rescue people trapped in floodwater and help with medical retrievals.

Cabonne mayor Kevin Beatty, whose territory includes Molong, says the picturesque town is devastated with shops in the main street inundated and people evacuated from homes and motels.

The Mitchell Highway is underwater and floating refuse is everywhere, including a large unidentified object that's blocking the major thoroughfare.

"I don't what it is ... there's either a big caravan or big shipping container sitting right on the highway on the bend in the middle of town," he told Sydney radio 2GB on Monday.

In the southern border town of Albury, the SES was called to rescue two children playing in a stormwater drain on Sunday, while at the central-western town of Woodstock the SES helped rescue people from six vehicles after a bridge was washed away.

The Bureau of Meteorology has cancelled a severe thunderstorm warning for the mid-north coast, the Hunter, the Central Tablelands, the northwest slopes and plains, the central-west slopes and plains, upper western and Northern Tablelands districts.

The bureau says the immediate threat of severe thunderstorms has passed but the situation will be monitored and further warnings issued if necessary.

SES Assistant Commissioner Nicole Hogan said flooding would continue to affect multiple communities in inland NSW this week.

The Lachlan River was rising at Forbes and the SES continues to support the community as people there recover from the recent inundation, she said.

The SES has delivered supplies of food, medicine and animal feed to 1000 residents cut off by floodwaters since severe weather began in mid-September and carried out 500 flood rescues.

SES Commissioner Carlene York said the volunteer workforce was fatigued and personnel have been requested from other states.

Flooding continues across western and southern NSW, in towns including Collarenebri, Walgett, Bourke, Condobolin, Hay and Albury.

South Australia has also seen flash flooding, causing havoc and closing some schools on Monday.

Flash flooding hits Mornington Peninsula after Victoria sees more wild weather

Flash flooding has hit Victoria's Mornington Peninsula, where residents were warned to stay indoors amid a sudden downpour.

A watch and act alert was issued for Mount Martha, Mornington, Hastings and Dromana on Monday morning as heavy rainfall caused localised flash flooding and building damage.

Residents were told to stay inside and away from floodwaters as the severe thunderstorm hit.

Victoria SES chief officer Tim Wiebusch said on Monday volunteers responded to more than 400 calls for help, most of which came in the early hours of the morning as storm cells moved across the state.

He said the Mount Martha and Mornington areas were hit with 40-50mm of rain in a few hours and there had been 23 flood rescues in those regions.

"A range of the rescues this morning have been people attempting to drive through flash flood waters but also (people) seeing water levels rise around their houses very, very quickly," he told ABC TV.

Mr Wiebusch said there had also been significant downpours in the state's northeast overnight, including 60 to 70mm of rainfall in some areas.

There was major flooding at the Murray River in Albury-Wodonga and that was expected to flow downstream to Yarrawonga and Tocumwal as more rain fell.

Mr Wiebusch said flash flooding was expected to turn into major riverine flooding in the coming days as already saturated catchments felt the impact of the extra water.

The Bureau of Meteorology issued severe thunderstorm warnings for parts of central and northeast Victoria on Sunday, including for Rutherglen where 28mm of rain fell in just 30 minutes during the afternoon.
