More rain is on the way in New South Wales this week, as the sodden land struggles to catch a break during the latest La Niña season.
According to the Bureau of Meteorology (BOM), a new trough and associated low pressure system is expected to move across the western region during Monday before progressing eastwards.
BOM forecaster Stephen Stefanac said this would generate showers, rain and the chance of thunderstorms in many areas throughout the week.
He said it was looking like southern NSW could expect more rain than the north.
"It is not looking as heavy as the previous week, but there might be some localised falls [across the state]," he said.
Mr Stefanac said the central west and south west slopes regions would likely pick up five to 10 millimetres, with isolated heavier falls possibly reaching 30 to 50mm in some areas.
There is uncertainty for the south-east, which will potentially receive 20 to 30mm on Wednesday, with isolated falls of more than 50mm.
Mr Stefanac said the northern coastal region may receive isolated falls of 10 to 20mm from late Tuesday.
Looking to the end of the week, Mr Stefanac said it was expected to clear up for western NSW, with showers persisting along the east coast until next weekend.
Major flooding still an issue
Meanwhile, prolonged flooding in many of the state's northern, western and southern forecast districts continue with many flood warnings still in place.
In the last two weeks, the SES has responded to 825 calls for assistance and 59 flood rescues.
NSW SES spokesperson Andrew Edmunds said major flooding was still impacting Gunnedah in the state's north, with the river peaking at 8.24 metres on Saturday morning.
He said while it was "slowly starting to recede", it was expected to remain at major flood level for the remainder of the weekend.
In other parts of the state, Wee Waa and Warren are expected to remain isolated by floodwaters for many days, with SES conducting resupply operations to residents, delivering essentials such as water, food and medicine.
"If you are impacted by floods and you haven't yet sought assistance, please do give the SES a ring," Mr Edmunds said.
He said morale was tracking as well as it could be within regional units.
"The SES is one big great orange family; the camaraderie and sense of contribution the volunteers get is second to none," he said.
"We are very fortunate to have over 10,000 volunteers in the SES and they are very supportive of their local communities."
Mr Edmunds reminded residents across the state to remain vigilant heading into the Christmas season.
"The long term forecast of a La Niña will certainly exacerbate the current flooding that we've seen with multiple systems anticipated to see prolonged or renewed minor to major flooding in the coming weeks and months," he said.
"We've got saturated catchments and full dams and very high rivers.
"It is going to stretch people and the community; it will test everyone's resilience.
"It is important to make sure people are prepared, they know the risks and they monitor the forecast in their areas, so they know if they need to act on their emergency plans."
Hailstorm surprises Mid North Coast
Mr Edmunds said there was up to 22 storm-related jobs in the northern zone on Saturday, after a grim-looking weather system came rolling in.
Following a sunny morning, the Mid North Coast was lashed with more rain and hail in some areas.
SES deputy commander at the Kempsey unit, Ray Walkden, said they received nine call-outs for hail and wind damage.
"All those jobs were attended by a strike force with about seven people and was completed by 7:30 last night," he said.
"We referred three jobs to council and two jobs to Essential Energy because powerlines had come down out at Euroka."
Despite the pre-warning, Mr Walkden said he didn't expect the weather to turn as quickly as it did.
"We kept seeing this cloud coming in from the west and then bang it hit and we started getting calls from everywhere for damage," he said.
He said the unit responded to an additional call for help this morning.
