The State Emergency Service says it's on standby to assist any parts of the state impacted by the deep low that's bringing heavy rain and winds.
There's a flood watch for at least three river systems in the state's south.
Here on the Tablelands, the Bureau of Meteorology has issued a sheep grazier's alert.
Region Controller for the North West Region, Col Malone, says his crews are ready to help other areas affected if called upon.
"Yeh, look, across the state any time when we've got potential activity we talk to our local units and we've sounded them out just to be aware and alert that there might be a call up for assistance," he said.
"So, they've had a talk to their families but, all in all at this stage, we're just looking after our patch and ready to go and help our colleagues if needed."
Col Malone says the Northern Tablelands will receive some very cold weather over the next 48 hours.
Farmers are warned of potential lamb losses during the cold conditions.
Col Malone says his crews are door-knocking locals.
"We're just preparing over the next two nights we're expecting to see maybe a little bit of snow out around Glen Innes and up towards Tenterfield," he said.
"There's just some light coverings at the moment, so our guys are talking to their local residents to make sure everyone's OK and aware there's a few cold nights coming our way."
