Thousands of residents were ordered to evacuate southwest Sydney, Australia’s biggest city, on Sunday with torrential rain and damaging winds pounding the east coast and floods expected to be worse than those that hit the region in the past year.
Heavy rain and overflowing dams and rivers all combined to threaten flash floods and landslides along the east coast from Newcastle to Batemans Bay in New South Wales state, and rain was expected to intensify on Sunday night.
“If you were safe in 2021, do not assume you will be safe tonight. This is a rapidly evolving situation and we could very well see areas impacted that have never experienced flooding before,” New South Wales emergency services minister Steph Cooke said in a televised media briefing on Sunday evening.
Earlier in the day, she urged people to reconsider holiday travel, with the rough weather had hit at the beginning of the school holidays.
“This is a life-threatening emergency situation,” Cooke said.
More than 200 millimetres (8 inches) of rain have fallen over many areas with some hit by as much as 350mm, the Bureau of Meteorology said, warning of flood risks along the Nepean and Hawkesbury Rivers.
Camden in southwest Sydney was underwater, and the weather bureau predicted water levels in the areas of North Richmond and Windsor northwest of Sydney would peak at higher levels than in the past three major flood events since March 2021.
“This could get significantly worse over the night,” State Emergency Service Commissioner Carlene York said.
The heavy rains caused Sydney’s main dam to spill early Sunday morning, water authorities said, adding that modelling showed the spill would be comparable to a major spill in March 2021 at the Warragamba Dam.
“There’s no room for the water to remain in the dams. They are starting to spill. The rivers are flowing very fast and very dangerous. And then we have the risk of flash flooding, depending on where the rains are,” York said.
There have been close to 2,000 calls for assistance on Sunday and in the past 24 hours, 29 people have been rescued from floodwaters, including one woman who was hanging on to a pole for an hour as workers struggled to reach her.
The body of a man who fell out of a kayak was pulled out of Sydney Harbour, police said, adding that the circumstances were under investigation but appeared to be linked to the windy conditions.

The government of Australia has provided the state with 100 troops and two helicopters to aid with any rescues, Defence Minister Richard Marles said on Sky News.
