'Brace yourselves': More than 100,000 without power after storms lash southeast Queensland

Southeast Queensland has been battered by damaging thunderstorms overnight, that dumped hailstones the size of tennis balls and cut power to more than 100,000 properties, with disruptions to trains Monday morning.

The weather system moved in Sunday night bringing severe lightning, large hailstones and torrential rain with strong winds.

Winds gusted to more than 110km/h, and bringing down power lines, resulting in more than 100,000 homes and businesses in darkness at the height of the chaos, according to Energex.

A boy taking a shower in Ferny Grove was hit with a bolt of electricity at about 6.45pm, the ABC reports.

He was rushed to Prince Charles Hospital with non life-threatening injuries, but is reportedly conscious and breathing though suffering leg pain.

The worst hit areas included Logan City and Brisbane, with power cut to 58,000 and 30,000 properties respectively. About 15,000 customers also had no electricity at Moreton Bay.

Residents at Boonah, on the Scenic Rim, posted images of hailstones the size of tennis balls and forecasters said 90km/h wind gusts were recorded at Amberley, Redcliffe, Inner Beacon, Redlands and Archerfield.

The storm chaos continues Monday morning with trains suspended in both directions on the Gold Coast, with further interruptions between Kingston and further south.

Services between the Gold Coast and Beenleigh have been suspended due to the overnight storm, with commuters told to expect delays of up to 45 minutes.

About 60,000 homes and businesses remain without power this morning, including childcare centres and schools, so Queensland parents are being told to call ahead before sending children this morning.

Sunshine State heatwave continues this week

The dangerous system prompted a severe weather warning from the Bureau of Meteorology as it swept across the region on Sunday evening.

Queenslanders have been warned to brace themselves for another week of extreme heat after a scorching weekend that saw the mercury climb above 40C in some places.
Areas reached 8 to 10 degrees above average on Sunday, with outback Queensland towns like Birdsville and Thargomindah climbing above 44C while Brisbane peaked at 34C.

"There will a few more days yet. A lot of the areas won't cool down until the end of the week," a Bureau of Meteorology spokeswoman said.

On Monday Brisbane is forecast at 34C, Surfers Paradise 36C, Birdsville 44C and Rockhampton 41C, with extreme conditions expected to last through the week.

The heat has prompted concerns about the state's electricity supply, with Energy Minister Anthony Lynham assuring Queenslanders there's plenty of power.

"We still have significant reserves, we have enough reserve for between 750,000 and a million homes here in Queensland," Mr Lynham told reporters on Sunday.

Emergency services are reminding people not to wait until they are thirsty to drink water, and to check on elderly relatives and neighbours.

Energex confirmed the storm has caused massive damage to the network 500 power lines down, and it will be some time before the power is reconnected.

Forecasters warned residents to move cars under cover, be wary of fallen powerlines and seek shelter if necessary.
