Sydney storms: Homes washed away in NSW floods

Incredible video continues to emerge of the harrowing effects of NSW's wildest weather in the past five years.

Chilling amateur video shows the moment four homes were washed away after a harrowing storm hit Dungog in the upper Hunter region.


Trees have been brought down, cars flipped and there are reports of waves reaching over 11 metres high from the sheer force of gale force winds reaching speeds that could be classified as a low-level cyclone.

"They have been consistently gale force. Gale force is the threshold for being Cat-1," Weatherzone meteorologist Rob Sharpe told Fairfax.

"We have seen that in Sydney and the Hunter."

More than 20 people have been rescued from floodwaters and 180,000 homes and businesses are without power as storms continue to lash NSW.

State Emergency Service personnel and firefighters in Stroud, just north of Newcastle, have rescued 10 people from rooftops in the state's wildest weather in five years.
