Severe storms have dumped heavy rain across south-east Queensland, with flash flooding and power cuts causing peak-hour chaos in Brisbane.

Parts of Brisbane’s west recorded falls of up to 80mm as a days-long heatwave broke with rainfall which began in early afternoon.

Flooding in and around Brisbane’s CBD caused roads to be closed, with some cars caught in rising waters.

Storm warnings are still current Brisbane, Logan, Ipswich, the Lockyer Valley, Moreton Bay, Somerset and the Scenic Rim region.

“The heaviest rainfall has been recording at Moggill with just over 100 millimetres since 9:00am, Ipswich 92 mm… Oakey has recorded 43,” senior forecaster Brett Harrison said.

“The most intense rainfall we’ve had recorded was in the eastern parts of the Darling Downs including Toowoomba and Oakey, where we saw rainfall of the order of 25mm in 10 minutes.”

Falls of around 80 mm have been recorded in the Toowoomba region and in Brisbane’s west.

Wind gusts of up to 113 kilometres per hour have been recorded at Oakey.

The Graceville Railway Station in Brisbane’s south-west has been closed due to flooding in the pedestrian subway.

More than 3,000 homes in the south-east lost power, more than half of them in the Ipswich area.

Energex spokesman Danny Donald says most have now been reconnected.

“Out near Ipswich they’ve restored power to nearly 2,000 customers after weather took out power to areas around Rosewood,” he said.

“In Logan we saw around 700 customers lose power after a car slammed into a power pole, so it has been a busy afternoon in inclement weather, but overall crews are doing really well.”

The bureau says the storms will ease tonight but the heavy rainfall will continue.
