Fresh warnings have been issued overnight for major flooding in Queensland and NSW, as heavy rainfall continues across large parts of Australia’s east coast.

Sydney and much of Australia’s east coast were inundated with a month’s worth of rain on Friday, but residents in many of the impacted regions have been warned the worst of the deluge is yet to come.

More than 100 millimetres fell in many areas of Sydney in the 24 hours to Friday night alone, and rain was expected to intensify into this morning before easing later today and tomorrow.

The Bureau of Meteorology (BoM) forecasts severe storms to impact much of NSW today, with widespread heavy to locally intense rainfall and damaging wind gusts from Eden at the Victorian border and up into the Hunter Valley region all under warnings.

“Six-hourly rainfall totals between 50 to 90mm are likely, reaching up to 130mm over the Blue Mountains and Illawarra escarpment. 24 hour totals of 70 to 120mm are also likely, reaching up to 150mm over the Blue Mountains and Illawarra escarpment,” BoM warned.

While parts of western Sydney and the Blue Mountains, such as Penrith, Katoomba, Jenolan Caves, Springwood, Bilpin and Taralga, are being warned of “very dangerous thunderstorms”.

These are “likely to produce intense rainfall that may lead to dangerous and life-threatening flash flooding in the warning area over the next several hours”.

Those heavier falls will then head south, impacting Bateman’s Bay and surrounding regions across the day.

Adding to flood concerns for parts of western Sydney is the Warragamba Dam, which was at 96.3 per cent capacity on Friday night, with potential to spill in the coming days.

Residents around the Hawkesbury area have started sandbagging to prepare their properties.

NSW SES also opened an evacuation centre at Richmond Club.

Overnight, some residents in Chipping Norton, not far from Liverpool in Sydney’s west, were told to evacuate before midnight, due to the risk of flooding at Georges River.

Evacuation centres were set up at Club Liverpool and Bankstown Sports Club.

While properties in the Gronos Point area, including properties along Gronos Farm Road and Manns Road are being ordered to evacuate by 5am due to rising moderate flooding.

As of 4.30am (AEDT), there were 80 warnings from the SES, ranging from Bega in the south-east all the way up to Lismore in the north-east and inland to Moree and Boggabilla in the north-west.

The SES said it had already responded to more than 820 calls for help due to the weather by midway through the afternoon. 

Elsewhere in the city, travellers suffered significant disruptions due to the cancellation of more than 100 flights in and out of Sydney Airport.

While the city’s train network suffered major delays and cancellations after equipment was damaged at the key station of Redfern, just south of the CBD.

Transport for NSW was forced to move services to roughly every 10 minutes during the afternoon and evening peak, instead of the usual three to four minutes, due to the disruptions.

In addition to the rain, strong winds of up to 90km/h have been forecast by the weather bureau for much of NSW, which has also warned of the chance of “dangerous and life-threatening flash flooding” and damaging surf.

“The widespread severe weather risk is forecast to clear south of the Hunter and Sydney Metropolitan areas by sunrise on Saturday, the Illawarra by late Saturday morning and the South Coast by Saturday afternoon,” the BoM said.

“More isolated severe thunderstorms may redevelop on Saturday afternoon.”

In Queensland, multiple flood warnings were in place with heavy falls due to hit southern Brisbane, Logan and the Gold Coast. The worst of the forecast was for the Darling Downs.

The BoM said up to 100mm of rain could fall in a short period and, like south of the border, the threat of severe weather would increase today into tomorrow.
