50k On Evacuation Alert After Deluge Hits Sydney

By Staff, Agencies

About 50,000 people have been urged to evacuate their homes as floods hit Australia's largest city for the third time this year.

Parts of Sydney have received about eight months of rain in four days.

Roads have been cut off, some houses are underwater and thousands have been left without power.

Widespread flooding across Australia - driven by a La Nina weather pattern - has killed more than 20 people this year, many in New South Wales [NSW].

More than 100 evacuation orders have been issued across Greater Sydney for the current emergency.

People in another 50 areas have been warned to prepare to leave, as several major rivers flood. Severe weather is also hitting the nearby Hunter and Illawarra regions.

Some areas of NSW have seen 800mm of rain in four days, says the Bureau of Meteorology, almost a third more than the average rainfall Greater London receives in a year.

The downpour is expected to begin easing in Sydney on Tuesday, but gale-force winds are also forecast, bringing a risk of falling trees and powerlines.

"The emergency is far from over," according to NSW Emergency Services Minister Stephanie Cooke.

Authorities are urging locals to heed evacuation warnings, after rescuers were called to save people who were ordered to leave two days earlier.

For many locals, it is their third flood this year.
