NSW coast to be lashed by rain over next seven days due to low-pressure system

The east coast of NSW will continue to be lashed by consistent rain for the next seven days, with the Bureau of Meteorology (BOM) warning there could be flash flooding in parts.

In Sydney, footy fans have been soaked while watching the NRLW grand final, with no let-up all evening.

The weather pattern is part of a trough that began on Friday, bringing widespread storm activity to the west of the state, before moving east.

Temperatures have also dropped due to a cold front which has seen almost 10 centimetres of snowfall in the alps.

Senior BOM forecaster Jordan Notara said the trough was starting to form a low-pressure system off the central NSW coastline.

"That is going to bring some more rain and shower activity through most eastern parts of the state," he said.

"It may be heavy at times for areas around the central coastline, particularly during the parts of the morning hours [on Monday].

"We expect to see the continuation of generally wet conditions, unfortunately, through the next seven days, mostly around the eastern seaboard."

Murrurundi in the Hunter region received the highest rainfall, with 59 millimetres falling in the 24 hours to 9:00am Sunday.

Tumbarumba on the South West Slopes and Plains also received 59 mm during the same period, .

A man aged in his 70s had to be rescued from a house due to rapidly rising waters.

The NSW State Emergency Services (SES) said it had received almost 200 calls over the past 24 hours.

Its Singleton unit was called to a caravan park at McDougall's Hill in the Hunter region on Saturday night, when strong winds caused damage to several caravans and cabins.

Some structures lost their roofs while others had damaged or missing awnings.

Thredbo in the Southern Tablelands received 45mm and 43mm fell at Narrabri on the Northwest Plains.

In Greater Sydney, Castle Hill (31mm), Horsley Park (30mm) and Terrey Hills received the most rainfall over the same 24-hour period.

NSW SES chief superintendent Greg Swindells said more than 4,000 crew members were on standby in the Sydney metro region to respond to flooding or storm damage.

Mr Notara said the lingering trough would remain throughout inland areas, bringing storms, which could be severe, around Tuesday.

He said there was still a chance of rain in the north-western parts of the state over the next seven days.

However, it is not expected to be as heavy as it has been over the past two days, which will be welcome news for farmers who are in the middle of their harvest.

The BOM issued a warning for severe thunderstorms across the Northern Rivers which were likely to produce heavy rainfall that could lead to flash flooding, damaging winds and large hailstones.

The areas which could be affected include Lismore, Grafton, Casino, Kyogle, Yamba and Maclean.

The BOM earlier issued a warning for severe thunderstorms for the Mid North Coast, Hunter and North West Slopes and Plains, however thunderstorms are no longer occurring in those areas.
