More severe storms coming after hailstones, 130mm of rain smashes coast

Ferocious thunderstorms have swept across south-east Queensland overnight for the second evening in a row, bringing with it heavy rainfall, wind gusts and large hailstones.

Brisbane, the Gold Coast and parts of the Sunshine Coast have been drenched by flash flooding as the fresh bout of wild weather submerged streets in multiple suburbs.

The cluster of storms swept through most of the region – while some areas were hit worse than others, including Boonah in the Scenic Rim which was hammered with 80mm of rain in less than an hour.

The Sunshine Coast copped a heavy downpour, with 100mm of rain recorded in 60 minutes at Mountain Creek and Maroochydore.

Flash flooding rose over major roads near Caloundra as strong winds and heavy rain impacted visibility on the Bruce Highway.

Hailstones up to seven centimetres in size were reported to the Bureau of Meteorology.

The Gold Coast was lashed by 130mm of rainfall overnight too.

Moderate and minor flood warnings are still in place around the south-east this morning.

The weather has eased slightly however more storms are forecast to continue on and off today.

And another bout of severe thunderstorms is expected to unleash more wild weather across the region for the third day in a row tomorrow.

There were rain delays on the Sunshine Coast between Beerwah and Beerburrum with some services held up for almost an hour due to a signalling issue.

Meteorologist Shane Kennedy said the wild weather, which began on Friday night, would continue.

"Overnight on Saturday into Sunday, showers will develop into quite a broad rainband extending from the north-west all the way down to the south-east," Kennedy said.

"There is still that potential we could see further severe thunderstorms for the third day in a row ."

Residents across huge parts of Queensland have been told to be on alert for wild weather. Late on Saturday, there were severe storm warnings for dozens of towns and cities between Emerald in central Queensland down to south of the Gold Coast on the border.

Sudden storm hits Sydney

A snap storm caused delays at Sydney Airport on Saturday afternoon which left about a dozen planes unable to land.

Pilots circled the airport as they waited for the storm to pass.

Flights have since returned to normal.

A strong north-easterly storm hit the city's south and south-west the hardest.

The weather system brought heavy rain and gusts of 80km/h were felt in Penrith.

While the thunderstorms in NSW have eased, the bureau said they could redevelop.

A severe weather warning was in place late on Saturday night particularly for northern most parts of NSW.

BoM meteorologist Angus Hines said severe thunderstorms had been most likely to occur in Queensland so far.

"This is not only where severe thunderstorms are most likely to occur today, but this is where we could see even more significant weather impacts in the form of giant hailstones, potentially five centimetres or greater, and destructive winds 120km/h or stronger," Hines said.

"The region where we could see those really high-end impacts goes from western parts of Brisbane and the Sunshine Coast up into the hinterlands, across Toowoomba, into the Darling Downs then across the southern border ranges and into the north-western slopes of NSW."

Victoria appeared to have dodged any of the worst weather, with a severe storm warning cancelled by Saturday night.
