‘Extremely unstable’: Qld to be smashed by dangerous storms



Towns were being evacuated and schools closed in south-east Queensland on Thursday afternoon, ahead of dangerous thunderstorms that could bring more “life-threatening floods”.

Premier Annastacia Palaszczuk urged parents to collect their children from schools from north of Brisbane to Bundaberg, as soon as it was safe to do so, on Thursday.

“These are unprecedented times,” she said.

“It is extremely unstable weather conditions and, as a precaution, we would like our people to collect the children when they think it is safe to go out on the road and do so.”

The renewed alarm for south-east Queensland came as 500,000 people in NSW were warned to evacuate or be ready to evacuate as the epicentre of the flood crisis moved south. Greater Sydney, the Hunter and the NSW central coast were expected to be battered with intense rain on Thursday afternoon.

There was moderate to major flooding along the Hawkesbury and Nepean river systems. Weather bureau forecaster Helen Kirkup said the entire east coast was affected.

“Still a lot of showers around the region. We’ve got heavier ones up towards the central coast and north of Newcastle and they are going to continue through today, overnight, and hopefully easing off during tomorrow.”

The weather bureau later amended its warning for more storms, lightning and torrential rain in Queensland, saying that Friday would be the worst day. “Dangerous and potentially life-threatening” storms would bring more rain to already saturated catchments in the state’s south-east, the Bureau of Meteorology said.

Many schools were expected to remain closed in the storm area on Friday.

On Thursday, the town of Grantham was being evacuated ahead of possible flash floods. The nearby Lockyer Valley had 80 millimetres of rain in 24 hours.

Lockyer Valley Regional Council mayor Tanya Milligan urged calm.

“The Grantham siren was activated, to really prompt people to temporarily evacuate any of those low-lying areas. It is a precautionary but a really, really important safety measure,” she said.

Deputy Police Commissioner Shane Chelepy said emergency services and Australian Defence Force troops were door-knocking in Grantham to ensure residents were ready to flee.

“We’ve already had 80 millimetres there, so we would only need one more severe storm system over that, which would cause issues there, and that’s the same right across the areas that have been mentioned today,” he said.

The first storm cells struck overnight after the worst floods in the decade, which have killed nine people and damaged more than 17,000 homes and businesses.

Cyclonic wind gusts of up to 93km/h brought down trees and power lines and sparked another wave of 360 calls to the SES for help.

Ms Palaszczuk warned conditions would remain unstable across south-eastern Queensland for up to 48 hours

“I’m asking people tomorrow to think about not being on the roads and staying at home, the schools will open for children of essential workers,” she said.

“I’ve lived in Brisbane essentially all my life and I haven’t seen storms and floods like this all being thrown at us at once.

“We’ll get through it together. ”

BOM forecaster Laura Boekel said the thunderstorms brought a chance of more flooding and flash-flooding across the south-east.

“This is a very dangerous and potentially life-threatening situation for south-east Queensland,” she said.

She said the Lockyer and Bremer rivers and Laidley and Warrill creeks were likely to flood. There would also be moderate flooding at Ispwich during the day and major flooding by Thursday night.

Earlier on Thursday, six-centimetre hail pummelled Windera, north of Brisbane, while stones of a similar size smashed into the southern town of Inglewood. Brisbane city had 48 millimetres of rain in just half an hour.

“That’s a severe storm with some very intense rainfall. And what we have seen can indicate what we can expect for the rest of the day,” Ms Boekel said.

“We also saw giant hail – unlike the event we have seen over the past week, this isn’t a widespread area rain, it’s severe thunderstorms, and with severe thunderstorms come severe hazards and phenomenon.”

Ms Boekel said the main concern for Brisbane was not the river, but the creeks where there was potential for flash flooding.

“They cannot take any more rainfall. They are what we call saturated.”

‘Treacherous weather conditions’ in Sydney

About half a million people in NSW have been ordered to evacuate, or be ready to do so, as NSW Emergency Services Minister Steph Cooke warns many regions face “treacherous weather conditions”, with the next 24 hours critical.

Premier Dominic Perrottet said the floods in the Hawkesbury region “will be worse than they were last year”.

Along with the wash-up from the destructive floods in the Northern Rivers, the state was facing “a battle on two fronts”, he said on Thursday.

“We do believe that things will get worse before they get better,” he said.

“But my message to you is that we will get through this.”

The Bureau of Meteorology said rainfall levels could hit a peak of 250 millimetres and warned of life-threatening flash flooding and damaging winds with peak gusts in excess of 90km/h.

Major flooding is expected in western Sydney along the Hawkesbury, Nepean and Georges rivers, Colo and Macdonald rivers at Menangle, North Richmond, Penrith and Windsor, with dozens of suburbs on high alert.

The south coast is also subject to a minor flood warning for the Shoalhaven and Sussex Inlet.

The State Emergency Service has issued 76 evacuation orders affecting 200,000 people and 18 evacuation warnings have been sent to nearly 300,000 people.

The Nepean River at Penrith will reach nine metres, bringing moderate flooding while the Hawkesbury River at North Richmond will reach 15 metres, bringing major flooding.

At Windsor, the Hawkesbury River will reach 14 metres by Thursday night – two metres above its major flood level.

Endeavour Energy advised customers in low-lying areas to prepare on Thursday for power cuts ahead of rising floodwater levels. Power had already been cut to more than 300 properties – mainly along the Hawkesbury River below Windsor.

Further north, thousands of properties remain without power after flooding earlier in the week.

Essential Energy said on Wednesday night it had restored power to about 2500 customers, but 18,000 more were still without power, and crews were unable to get into Woodburn, Broadwater and Ballina.

Abnormally high tides and damaging surf warnings are also in place for most of the NSW coastline, with east-facing beaches at greater risk.

Coastal erosion is likely and low-lying areas could also be affected by tidal flooding.
