Dangerous storms are forming over parts of southeast Queensland, with warnings they may lead to flash flooding, giant hail and destructive winds.

Queensland is expected to be lashed by more dangerous supercell thunderstorms bringing giant hail, torrential rain and destructive winds.

The severe thunderstorms are forecast to rapidly develop along the Great Dividing Range in the state’s southeast and push towards the coast throughout Saturday afternoon.

Damaging winds, large hailstones and heavy rainfall that could lead to flash flooding are likely, the Bureau of Meteorology warned.

“Already we are seeing severe thunderstorms on the NSW-Queensland border and Scenic Rim,” meteorologist James Thompson said.

“Very dangerous thunderstorms … supercell thunderstorms that could lead to giant hail and destructive wind gusts in excess of 125km/h.”

The Gold Coast, Brisbane, Sunshine Coast, Gympie, Kingaroy, Ipswich, Lockyer Valley and Scenic Rim may be affected.

People are urged to move cars undercover, secure loose outdoor items and stay indoors.

The forecast comes less than a week after two days of storms delivered a month worth of rain and flash flooding to some parts of the state, including Brisbane.

Tennis ball-sized hailstones pummelled the region on Tuesday and Wednesday.

Beachmere, near Caboolture, recorded 80mm of rain in an hour and 70mm fell on The Upper Lockyer, west of Brisbane.

Tiaro, north of the Sunshine Coast, recorded 51mm of rain in an hour with 22mm of it falling in five minutes.

Flash flooding affected some Brisbane areas at the height of the storms on Tuesday, which was the wettest October day in the city since 2010.
