The situation has prompted renewed warnings from the State Emergency Service (SES), after extraordinary footage of a car driving through floodwater emerged.

Larnook man Brandon Glover was on his way to get supplies about 11:00am yesterday when he was stopped by water across Kyogle Road.

"Obviously, we couldn't get past that bridge, so we got out and had a look and started filming it," he said.

"This car has just come down, didn't look, straight through it and then seconds after she got off it the whole bridge went.

"It was the whole bridge that just flushed straight down."

Mr Glover said the driver avoided disaster by mere seconds.

"I don't think she realises how close she was," the 31-year-old said.

"She just kept driving as soon as she got out.

"If you could hear the voice in the video, we blacked it out because I was swearing and carrying on, but yeah it was unbelievable."

Drive to conditions, SES warns

SES North Eastern Zone Commander, Chief Superintendent Greg Swindells, said the driver involved was extremely lucky.

"The footage shows very clearly what did happen as soon as they left that bridge," he said.

"The bridge was washed away.

"People drive through floodwater ... because they think it's safe, but what they're not aware of is the structural integrity of the road surface and the infrastructure around it.

"Again we're urging people, if it's flooded forget it, find another way."  

SES Superintendent Scott McLennan said drivers needed to take extra care because although the weather system was starting to settle, some rivers in the region were still rising.

"We just want people to pay attention to the roads and drive to conditions, or really reconsider travel altogether," he said.

"There are a couple of landslips, a couple of bridges have gone, and there are huge potholes right across the region."

More than 530 millimetres of rain has fallen at Nunimbah and Bald Mountain near Murwullimbah since Sunday morning.

The flood warnings follow 28 flood rescues by the SES across the Northern Rivers Region yesterday, most of which were campers that included 10 teenagers.

There were also 360 calls for assistance overnight and the town of Tyaglum is currently isolated with access roads that were affected by the 2022 floods damaged again.

Minor flood warnings are in place for parts of the Richmond, Paroo and Tweed Rivers, but minor flooding is no longer expected at Lismore on the Wilsons River.

The levy gates on the Tweed River at Murwillumbah have been closed as a precaution to protect businesses in the CBD from possible flooding.

A previous alert for people at Tumbulgum to prepare to isolate, as well has been cancelled.

Bureau of Meteorology duty forecaster Helen Reid said more rain was forecast for the coming days, but the worst of it should now fall above the Queensland border.

"We do still have potential for heavy rainfall and thunderstorms through the course of the day," she said.

"So given that we already have some minor flood warnings for rivers through that part of the world as well we do need to be mindful of an increase to that flooding situation."

'Really hard on people':

Dairy farmer Necia Davis said her property at Tyalgum Creek was already isolated.

"We were completely cut off yesterday, both ways to Murwillumbah were closed," she said.

"They closed the original slip that happened on Tyalgum Road two years ago.

"I think everybody was very nervous, anxious, like here we go again."

Tweed Shire Mayor Chris Cherry said some locals were still traumatised by the last flood emergency in 2022.

"You know this is really, really hard on people to have this happen," she said.

"And at a family time when you're normally just out there celebrating the possibilities of the year ahead.

"It's really hard to have people quite scared about what is happening, hopefully it gets better and not worse."
