Authorities are warning of potential flooding in parts of NSW as relentless rainfall is set to worsen over the coming days.
The state is being battered by heavy precipitation due to an unpredictable and complex weather system.
The northern and north-western parts of the state are in line to see intense rainfall, with the weather set to deteriorate in areas west of Tamworth and along the north coast this evening.

The NSW SES has warned there is a risk of flash floods due to the already elevated river levels and full dams from recent weather events.
Residents have been urged to be prepared in case the situation changes and to monitor warnings.
”We know the weather and flooding this year has been tiring for many of you, but please, stay ready and stay safe,” NSW SES Assistant Commissioner Malone said.
“Have an emergency plan in place, understand your own risk and know where you will go and what you will do if your home and family are impacted.”
NSW SES Deputy Commissioner Deb Platz said the wet weather is “likely to continue for the rest of the year” and warned residents against complacency.
Today brought up to 45mm of rain across the east coast from Jervis Bay up to the Queensland border, with some isolated totals of 75mm.
The wet weather is expected to peak tomorrow before easing on Friday.
Widespread rainfall up to 80mm is likely and isolated falls of 120mm are possible along the coast from Sydney to Ballina tomorrow.
Totals of up to 35mm are likely for those same coastal areas, while isolated totals of 60mm from Port Stephens to Byron Bay are possible on Friday.

Sydney CBD and the Greater Sydney area are also forecast to be battered by more rain over the next three days.
Bureau of Meteorology manager of hazard preparedness Steve Bernasconi said the widespread, moderate to heavy rainfall is due to a high-pressure system in the southern Tasman Sea drawing in moist air.
“This may not seem like a lot [of rain], but over three days it is,” Bernasconi said.
“What we have here is a significant rain event impacting most of the state.
“The main issue is flooding.”
The bureau expects the high-pressure system to start to move out to sea on Saturday, but warned there may be some lingering showers in the afternoon and evening.
The SES has fielded 330 calls and responded to 120 incidents so far.
Road closures are expected, particularly in flood catchment areas.
Flood watches across the state
There are 28 warnings in place across the state as of 4.30pm today, stretching from Menangle Park in Sydney’s south-west to Boomi on the border with Queensland.
Minor to moderate flooding is likely and isolated major flooding is possible for parts of the Mid North Coast, Hunter and North West Slopes from late today.
Minor to moderate flooding is also possible in the Hunter and Colo River catchments from tomorrow morning.
A flood watch and act alert is in place for Goangra and the surrounding suburbs.
Residents are urged not to enter floodwaters due to the steady and minor flooding in the area.
Advice alerts are issued in 27 other parts of the state.

NSW SES Assistant Commissioner Colin Malone said the organisation is preparing assets and personnel to respond.
“We’re sending aviation assets, high clearance vehicles and crews into the areas likely to be impacted by this rainfall,” he said.
“While we’re prepared for an increased volume of calls for assistance, we ask the community to prepare too.
“Stay across the latest warnings and advice via the Hazards Near Me app and set up a watch zone for your local area.”

SES flood warnings remain in place for communities in western NSW as floodwaters caused by a coastal low-pressure system earlier this month continue to move downstream.
Malone urged residents in impacted areas to have a flood emergency plan in place before waters rise.
Residents are being reminded to never drive through floodwaters.
