Dams discharged and flood warnings issued as rain buckets south-east Queensland

Queensland’s south-east is back on flood watch with more than 100mm of rain dumped on several soaked catchments, and dams releasing water ahead of more wet weather.

The Sunshine Coast suburb of Maroochydore recorded 122mm in the 24 hours to 9am on Sunday. Nearby Mooloolaba copped 112mm, while over 100mm also fell farther south at Parrearra Weir and inland at Mountain Creek.

Delivered by a low-pressure coastal trough north of Gladstone, the bucketing follows five deadly Queensland floods since December which scientists attribute to a second La Niña weather pattern in two years.

Brisbane fared somewhat better in the latest downpour, recording less than 24mm overnight, while the Gold Coast received 54mm.

More than a dozen flood warnings have been issued across the region by the Bureau of Meteorology and a flood watch is in place for catchments between St Lawrence and Brisbane.

Seqwater notified Pine Rivers and Moreton Bay region residents that the North Pine dam would start flood releases on Saturday evening. The utility said Youngs Crossing, downstream from the dam, would likely be inundated and Moreton Bay regional council would close the causeway.

“If you are downstream of the dams, stay away from fast flowing or deep water near waterways and flood plains,” it said in an alert.

Smaller dams between the Sunshine Coast and NSW border have also been overflowing or releasing water.

West of Brisbane, major flooding is possible along the Condamine river which is forecast to peak near 9.3 メートル, above its major flood level, 日曜日に.

Flooding is also on the cards downstream along the Balonne river with fresh surges expected over several days.

Shane Kennedy, a BOM forecaster, said on Saturday residents at Dirranbandi and Hebel could be isolated by flood waters into next week.

“It’s just about preparing and making sure that everyone is loading up with supplies before that happens again," 彼は言った.

“We’ve seen multiple peaks this season around throughout that Condamine and Balonne system.”

Light coastal showers are likely to continue through the week, with central Queensland also in line for rain before conditions ease.

“Next weekend we might finally see a bit more sunshine in the south-east,” Kennedy said.
