Parts of inland NSW remain on high alert for flooding despite a short reprieve from heavy rain, as authorities reinforce safety warnings in the wake of a five-year-old boy's death.
Bureau of Meteorology forecasters are shifting their focus to early next week, when southern and central inland parts of the state could get "considerable" falls on Tuesday and Wednesday.
"It's a bit early to know exactly how high the flood peaks will get as a result of that rain, but it's definitely something that our hydrology team will be checking out pretty closely over the next day or two," senior meteorologist Jake Phillips said.
"It definitely will exacerbate some of those flood peaks and could send some of them either into prolonged major flooding, or raise them from moderate into major, potentially."
Among places authorities were concerned about on Saturday was Gunnedah, where the Namoi River peaked at the major flood level of 8.24 metres in the morning.
State Emergency Service spokesman Greg Nash said people downstream of places like Gunnedah on the river should keep abreast of the latest flood information.
"It's anticipated that water will move downstream slowly and may isolate some areas," Mr Nash said.
Wee Waa was isolated by road on Saturday, but the emergency service deployed resources to the town.
A five-year-old boy was found dead on Saturday afternoon after a vehicle was swept away by floodwaters at Tullamore, northwest of Parkes, in central western NSW.
The boy's parents were reportedly able to remove restraints from two younger children in the car, but weren't able to free the older boy.
His death has prompted renewed calls for people to take the dangers of floodwaters seriously, with Mr Nash saying a river or creek's conditions could change between morning and afternoon.
"We have some very resilient communities and some communities that are very much aware of their flood risk," he said.
Mr Nash said, "We want people to drive to the conditions, and if you find a flooded or a damaged road as a result of flooding, to stop, turn around, find another away, it's not worth the risk to push on."
In the 10 days to Saturday, the emergency service had fielded more than 800 requests for assistance in NSW, which included nearly 60 flood rescues.
In the 24 hours to about 5.30pm on Saturday, the emergency service received 120 requests for help and five flood rescues.
