Four people have been rescued from floodwaters in the north of NSW.
Emergency services carried out two separate rescues when a car was swept away in floodwaters at Burrell Creek and Muswellbrook.
The first incident saw a Landcruiser swept from a small causeway by rising floodwaters in Burrell Creek about 3.30pm yesterday.

The car was carried 200 metres downstream where it became wedged on rocks in the middle of the flooded creek.
Two men, aged 46 and 30, went into the floodwaters to try and help the trapped 35-year-old driver.
Five officers attended the incident.
One of the officers found a rope and threw it about 10 metres to the three stranded men.
Police rescued them by pulling them individually across the floodwaters.
All three were assessed at the scene by paramedics but didn't need further treatment.

In the second incident, a Toyota Hilux had attempted to cross the Rosebrook Spillway in Muswellbrook before being swept from the road into floodwaters around 10.20pm last night.
Police found the car about 400 metres from the spillway with floodwaters rising over the vehicle's bonnet.
Officers tried to winch the car from the water but were unsuccessful.
The 52-year-old driver climbed out of the car and tried to swim against the floodwaters but instead began drifting further downstream with the vehicle.
Police waded through the water to assist him before he was safely returned to shore.
He was treated by paramedics at the scene before being taken to Muswellbrook Hospital for observation.

Assistant Commissioner Peter McKenna praised the officers involved in both the rescues.
"In the face of extreme danger, these officers acted quickly and courageously to ensure the stranded motorists were safely rescued," Assistant Commissioner McKenna said.
"Floodwater is extremely dangerous as it can have fast-moving undercurrents that can wash people and vehicles away."
The wild weather that has hit NSW has become dangerous, as a woman suffered spinal injuries after a tree fell on a car in Sydney's south overnight.
The NSW State Emergency Service (SES) received more than 850 calls for help overnight and performed 34 flood rescues.
Assistant Commissioner McKenna urged people not to drive, ride or walk through floodwaters.
More wet weather is forecast in the coming week with the state already saturated with rain.
The rain has caused Sydney's Warragamba Dam to hit capacity and begin to spill.
Further flooding is expected as a result of the deluge.
