Sydney Floods – disaster unfolding across parts of Sydney, regional NSW.

Breaking News: Parts of western Sydney will flood as record rain continues to come down in Sydney and surrounding regions.

There is potential for “very significant flooding” in Greater Sydney, particularly around the Hawkesbury-Nepean river system.

“For us, public safety is the main message. You know – stay out of the floodwater. Keep across the Bureau’s warnings. Listen to SES advice, and it’s still an evolving and dynamic situation,” the BoM’s national flood services manager Justin Robinson said.

The Warragamba Dam is set to start spilling this afternoon in Sydney, with flood waters set to rise across the region.

WaterNSW said in a statement that heavy rain is now generation large inflows that are “filling Sydney’s supply dam network.”

Other dams, such as Napean, Cataract, Cordeaux and Avon are also expected to reach capacity and begin spilling water today.
