Would you drive through this? NSW rescuers reveal 'deceptive' floodwaters

Multiple rescues across NSW due to deceptive floodwaters has sparked a warning from authorities.

NSW State Emergency Services (SES) have released an image of a flooded road in Tamworth which looks deceptively shallow.

"This photo is very deceptive, what you can't see is the rapids at the other end," NSW SES said.

A small Subaru wagon drove around road closed signs into the pictured floodwaters yesterday evening.

"The vehicle got stuck halfway across a strong, fast-flowing creek," SES crews said in a Facebook post.

SES crews from Gunnedah and Tamworth assisted the passengers and a dog from the vehicle.

It has sparked a fresh warning from NSW SES for people to avoid driving through floodwaters or swollen rivers.

"It's important to note that some roads may be cut off with little warning," NSW RFS said.

"So even if there are no warning signs or road closed signs never drive through floodwaters."

A number of other rescues have taken place in NSW over the past week after heavy rainfall caused flash flooding in the Hunter region and north-east of the state.

Tamworth and the Hunter region saw major flooding yesterday and it even blocked roads cutting off workers and HSC students.

Heavy rainfall has resulted in flooding across multiple parts of the state.

Weatherzone said November has been a particularly wet month for NSW with more than two months' worth of rain during the last three weeks.

More flooding is expected as showers and thunderstorms continue to lash the state over the next week.

It comes as the Bureau of Meteorology declared a La Niña in the Pacific Ocean, indicating wetter-than-normal periods for eastern, northern and central parts of Australia.
