The Bureau of Meteorology says it expects the low pressure system off the North Coast to move into the Tablelands and North West Slopes and Plains weather districts on Saturday.
Meteorologist, Sarah Hicks, says more rain is expected on the Tablelands, with 90-kilometre an hour wind gusts over the more exposed areas.
She says the rainfall totals in this region won't be anything like the torrential falls being experienced on the coast.
"We're expecting to see that bring widespread rainfall of about 10mm to 25mm over much of the Northern Tablelands and the North West Slopes and Plains and, locally, we could see around about 50mm," she said.
"That's probably more likely to be over eastern parts of the Northern Tablelands and southern parts of the North West Slopes and Plains."
But Ms Hicks says the Bureau believes the system's time in the New England North West will be short-lived.
"We're expecting that during the day on Saturday it'll weaken from a low pressure system into more of a trough situation and towards the evening we would expect the rain areas to be easing to more of a showery situation," she said.
"But we are still expecting to see quite a few showers around for much of Sunday."
Meantime, Acting Region Controller with the Namoi SES, Andrew Galvin, says the weather on the North Coast has seen an out-of-area request for support from the New England North West.
He says most of the damage on the coast has been caused by tree falls and inundation.
Andrew Galvin says local volunteers are offering assistance for the next four or five days, but more could be asked to lend a hand.
"I'm over at the Mid-North Coast region assisting in their operations centre and we also have specialist mapping people and a number of other volunteers working with our information management systems," he said.
"The SES at this stage has had 1,000 calls for assistance and the main job has been removing trees from across driveways and roads, or [that have fallen] on houses."
