About 600 gigaliters of water spilled on the Varragamba Dam, as residents who survived a flood in the Hawkesbury-Nepian region a year ago are warned to prepare for the “hard night” ahead.
“These are our worst fears,” Deputy Prime Minister Paul Tull said shortly before 6 p.m. on Wednesday.
“It will get worse before it gets better.”
He said any residents affected by the floods last March, when about 460 gigalitres crossed the wall of the Varragamba Dam, should leave now because the Georges River probably exceeds the height seen 12 months ago.
The Redbank Dam is likely to fail, flooding homes near North Richmond, and rivers continue to rise.
“We don’t want to see situations where people are on the roofs of their homes waiting to be rescued,” Mr Tull said.
SES has 31 evacuation orders and warnings, including last year’s trail of the Hawkesbury-Nepian floods.
“It will be a difficult night for the residents of the area,” Mr Tull said.
“Conditions are deteriorating rapidly,” says meteorologist Bureau of Metrology Dean Naramor.
“A dangerous situation is developing. We expect the rain to continue, ”he said.
DSNS Commissioner Carlin York said residents need to begin preparations for the evacuation, and further evacuation orders are likely to be issued on Thursday night.
“This is a very serious situation, and the rain was much heavier than we expected … we saw record levels that we have not seen in recorded history,” said Ms. York.
“We don’t want to leave it in the middle of the night … you need to be ready now.”
High traffic on the SES website makes it difficult for people to access information, but Ms York said warnings will continue to be posted on social media and other emergency services.
Warnings were issued when it was confirmed that two more people died in the floods that engulfed NSWas the great Sydney prepares for its own “life-threatening” stream.
Confirmation of recent tragedies came when the first warnings of an evacuation from the Sydney suburbs ahead of torrential rains were expected on Wednesday, expected in a few hours.
