Once-serene waterfall transforms into raging torrent in NSW deluge

A once-serene waterfall in the Blue Mountains in Greater Sydney has been transformed into a raging wall of water, amid record-breaking rain.

An east coast low is battering the entire NSW coast, with Premier Dominic Perrottet saying "much of the state is underwater".

The footage was filmed yesterday as the Lstmtns team explored Minnehaha Falls.

Minnehaha Falls has been transformed by the record rains hammering NSW.

The conditions come almost a year after western Sydney flooded.

"Last year was insane, our Lstmtns team had never seen so much water. Now almost a year later we are seeing even more water. It's incredible to see," a team member told 9news.com.au.

"An incredible amount of water that has fallen and that is forecast to continue.

"Our thoughts are with all those that may have livestock or homes at risk."

Team members had to shield their faces as they ran past the wall of water near Echo Point.

A pair of hikers had to be rescued from the Blue Mountains on Tuesday after the track they were walking on flooded.

"Emergency services were called to Wentworth Falls, in the Blue Mountains National Park, after a 55-year-old man and 33-year-old woman needed to be rescued due to rising water on their walking track," NSW Police said.

"In light of this incident, and current weather warnings, police urge members of the public to avoid bush walking until the current wet weather eases, and if you do proceed, ensure you are well prepared for the conditions"

To be adequately prepared, NSW Police advises bushwalkers to:

  • Pack adequate supplies of food and water, as well as navigation and first aid equipment
  • Register your planned route and aim to stick to that
  • Follow the map and walking trails and do not ignore warning signs and barriers
  • Tell friends and family when you expect to return
  • Carry an emergency beacon
