3 Killed in Floods After 300mm of Rain in New South Wales, Australia

Storms across the Sydney Metropolitan, Central and Mid North Coast, Hunter and Illawarra areas of New South Wales, Australia have brought widespread destruction and raging floods.

With strong winds of up to 100 kmh, the storms downed trees and left as many as 200,000 homes without power.

The storms also dumped over 300 mm of rain in some areas in a short period, resulting in raging flash floods across Sydney, Newcastle, Hunter Valley and surrounding areas.

NSW Premier Mike Baird is asking people to be patient as emergency crews deal with life-threatening situations. He also urged people to start to head home from work, with weather conditions expected to worsen.

One of the worst affected towns is Dungog, where at least 3 people are thought to have died, with further reports of another person still missing. Australia Bureau of Meteorology say that 312 mm of rain has fallen in Dungog in the last 24 hours.

Emergency services minister David Elliott described it as a “once in a decade” storm. NSW emergency crews carried out around 50 flood rescues. At least 10 people had to be airlifted from roofs by helicopter after they took refuge from the floods in Stroud, near Newcastle.

Dungog, New South Wales

Dungog is a small town of around 2,000 in habitants, located in the Hunter region about 70 km from Newcastle and 250 km from Sydney. The streets of the town were turned into raging rivers in a matter of hours by the heavy rain brought by the storm. One local observer said that the flood water came from nowhere, and rose so quickly it was like a roar, rushing through the streets.

Several people were rescued by helicopter after they took refuge on the roofs of their homes. SES also reported that a school bus was swept away by the floods near the town. Later reports said there were no children on board and the drive was successfully rescued.

Residents of Dungog have been ordered to evacuate the area and either stay with friends or relatives outside the flood zone, or at an evacuation centre set up in a local school.

The town has suffered widespread damage. The torrent was so strong that several houses were dragged from their foundations and swept away by flood water. The video clip below was filmed by a local resident.
