Sydney — Dams near Sydney overflowed on Thursday after days of torrential rain, as Australia braces for more storms expected to bring dangerous flash flooding to the country’s east.

Recent downpours have brought relief to areas ravaged by bushfires and drought — as well as chaos and destruction to towns and cities along the eastern seaboard.

On Thursday, Nepean Dam south of Sydney was at full capacity and spilling over, with video footage showing excess water cascading over the dam wall and downstream.

Two other dams in New South Wales (NSW), Tallowa and Brogo, were also overflowing and more dams could reach capacity in the coming days, a WaterNSW spokesperson said.

Sydney’s dams have seen water levels spike dramatically — the Nepean was just a third full less than a week ago — though many inland areas facing severe water shortages missed out on the flows.

A devastating, months-long bushfire crisis that killed 33 people has effectively been ended by the downpours, with just one blaze yet to be brought under control in NSW.

Hundreds of people have been rescued from floodwaters in recent days. Police said a man’s body was discovered in a flooded river on Queensland’s Sunshine Coast on Thursday, though the cause of his death was not immediately clear.

Wild weather is set to ramp up again from Friday, with the Australian Bureau of Meteorology forecasting former Tropical Cyclone Uesi bringing “damaging to destructive winds” and heavy rainfall to remote tourist destination Lord Howe Island.

Senior meteorologist Grace Legge said storms were also expected for Queensland and NSW — with areas still recovering from bushfires likely to be hit again.

“Any showers and thunderstorms that do develop are falling on already saturated catchments, so there is a risk with severe thunderstorms of flash flooding,” she said.

Emergency services have warned residents in affected areas to be cautious in the dangerous conditions.
