One person died as severe thunderstorms swept across southeast Queensland on Thursday, ABC News reported.

A yet-to-be-identified person died after a tree fell on their car around 3:00pm at Hillcrest, south of Brisbane.

Meanwhile, in Toowoomba, four cars were washed away by flash flooding on the Darling Downs. It is believed the drivers managed to escape before the cars were carried away by the waters.

Flash flooding on the Darling Downs in January killed two people who were swept to their deaths.

ABC News reported emergency crews were called to several homes in Brisbane's south due to severe flood and hail damage. Some suburbs in Brisbane are covered in hail due to the bad weather.

"All of a sudden it was like pea soup here and the rain was really heavy and some big hail came through," a Parkinson resident told ABC.

"When I say big, it was big enough to cause superficial damage, like punching holes in the pergolas... just a hell of a storm."

Boonah resident David Edgeworth says rain was very heavy in his area for almost five hours.

"Very heavy rain here started about 2.30pm, 2.45pm... It didn't let up. It's been raining pretty much constantly since then and we've had on our rain gauge 136 millimetres, so that cell that went through slow moving dumped a lot of water on us."

The stories are the same, north of Brisbane.

"We had about 37 mills in about 50 minutes, I had to go down to the corner store and we were actually getting some flash flooding across the road, just the amount of rain we were getting," a resident told ABC.

Weather forecaster David Grant says southeast Queensland residents can expect further wild weather in the coming days.

"It's always going to be that peak during the afternoon into the early evening when we do have thunderstorms so they'll ease up overnight, but we've got a couple of days of thunderstorms ahead across the southeast," he said.
