Children who attend a host of schools scattered across the NSW mid-north coast, Hunter and central coast have been told to stay home on Monday.
"If a school is closed, it will not be offering supervision to students," the NSW Department of Education said in a statement on Sunday, noting learning-from-home resources would be made available for students.
The list of schools to be shuttered is available on the department's website.
Wild weather hammered northern NSW across the weekend after floods and snowstorms stranded cars and cut power to homes.
A search for a woman swept into floodwaters in NSW's Hunter region is ongoing.
Emergency workers were called north of Cessnock on Saturday night after reports a Mini car was grounded due to the floods.
The driver, a 27-year-old woman, managed to get out but the passenger, 26, was dragged away with the strong current.
"We've had a number of areas in the Hunter Valley that have been prone to evacuation orders and warnings in relation to floodwaters," Hunter Valley police superintendent Steve Laksa said.
"I'd just ask the community to take heed of those warnings and do not enter any waterway."
State Emergency Service crews responding to the emergency saved a 40-year-old man who was stuck in a nearby tree due to floodwater.
The man was swept out of the tree but rescuers followed him into the water and managed to pull him to shore and he was taken to hospital.
Tens of thousands of households in the eastern state spent a night without power as heavy rain, floods and unprecedented snow wreaked havoc.
Since the bad weather began, the NSW SES has responded to more than 3600 calls for assistance and responded to 2,092 incidents, including 25 flood rescues.
There are still more than 50 warnings current for residents across the Mid North Coast, Upper Hunter and New England regions.
But a severe weather warning was cancelled on Monday ahead of more settled conditions, although riverine rises remain a risk as floodwater moves downstream.
Minor flood warnings are current for the Manning, Gloucester, Macleay, Severn, Paterson, Williams, and Gwydir Rivers.
High winds and storms also battered the other side of the country in Western Australia.
