Sydney weather: Heavy rainfall, flooding as new severe weather warnings issued

Renewed fears for flooding, heavy rain and public transport havoc have hit Sydney, with the torrential weather showing no signs of easing.

Some parts of Sydney are set to be lashed with up to 120mm of rain on Monday, with more severe weather warnings issued for a large swath of the state’s coast.

On Monday morning, the state’s Bureau of Meteorology warned heavy rainfall could lead to flash flooding today and on Tuesday, with thunderstorms also possible.

Warnings have been issued across Metropolitan and Greater Sydney, as well as the Mid North Coast, and Illawarra. Some parts of the South Coast, Central Tablelands, Southern Tablelands, North West Slopes and Plains and Northern Tablelands will also be affected.

“An upper low over northern NSW will slowly move south today and into Tuesday,” the BOM NSW reports.

“A surface trough off the NSW coast is expected to strengthen, bringing moist south-easterlies onto the Mid North Coast, Hunter, Sydney Metropolitan area, Illawarra, South Coast, and parts of the Tablelands and Northwest Slopes and Plains.

“Six-hourly rainfall totals between 70 to 120mm are possible.”

The torrential weather has caused massive delays on Sydney’s train system, with commuters urged to expect cancellations and delays. People have also been asked to work-from-home if possible.

“Due to severe weather conditions, significant delays and cancellations are expected on most Sydney Trains, NSW TrainLink Intercity and Regional trains services,” a statement from TfNSW read.

“Trains will run to a changed timetable and will take longer than normal to reach your destination. Avoid any non-essential travel and if you do need to use the network please plan ahead and leave plenty of extra travel time.”

There are also fears the heavy rainfall could trigger renewed flood risks for the already embattled areas along the Hawkesbury River and Colo River.

Minor to major flood warnings have been issued for the Hunter River and Wollombi Brook at Bulga, Singleton and Maitland, with warnings also in place across the Hawkesbury Neapean Valley area.

The NSW SES warned this could lead to a dangerous “bathtub effect” in the Hawkesbury-Nepean Valley. The area is prone to some of the highest flood risks across Australia, due to the five major tributaries which flow across several narrow areas that may choke the water flow, The Daily Telegraph reports.

Some of the worst flooding could occur in the Wallacia, Castlereagh, and Sackville due to the geography. Elsewhere in the region, water levels also reached to 20m above normal levels in Wallacia and 12m in Castlereagh.

Moderate flooding is also expected in Nowra and Terara due to rising levels reported for the Shoalhaven River.

NSW SES have urged residents across the state’s coast and northern inland to prepare their properties. Properties which may be cut off due to rising water levels or flash flooding have been advised to stock up on essential supplies like food, fuel and medicine.

Farmers have also been asked to lift pumps and relocate livestock and equipment to higher ground.

The continued wild weather comes after towns in the state’s Northern Rivers were hit with catastrophic flooding last week.

The Sydney Morning Herald reported more than 2000 homes and businesses have been declared unliveable, with fears that two out of three homes in Lismore will remain unhospitable unless they’re completely rebuilt.

Visiting one of the hardest hit areas in Lismore, Premier Dominic Perrottet said the “momentous” recovery could take years.

“It’s been incredibly confronting,” he said, speaking to press in the town of Coraki.

“The scenes here are unimaginable and devastating. It’s pretty emotional.”

Currently the death toll from the flooding in NSW remains at five, while 11 people have died in Queensland.
