THE “rain bomb” that drenched Brisbane sparking record floods in northern NSW will turn into an east coast low-lying day, dumping up to 2mm of rainfall across Sydney as Sydney goes on a “life-threatening” risk on Wednesday.

Sydney, home to more than 5 million people, and several adjacent areas could get up to 150 millimeters (0.16 in) of rain in six hours Tuesday afternoon, the Bureau of Meteorology said.

Sydney has an average rainfall of just 138 mm for March, official figures show.

Nine people have been killed since initial flooding began last Thursday, with rescue teams searching Monday for at least four still missing.

The flood is heading south out of the state towards New South Wales, where there has been the worst storm to strike the region since a disaster that started in 2011.

‘What we are seeing today is unprecedented and the advice that we have received is we would expect things to get worse,’ New South Wales Premier Dominic Perrottet said in a televised address.

Hundreds of people are still trapped in their homes in the northern NSW town of Lismore, which has been hit by its worst flooding on record, with some said to have spent the night on roofs.

Mayor Steve Krieg told the Channel Seven news network nine people were still missing and 400 rescues were still pending.
