Residents at Logan, south of Brisbane, are cleaning up after yesterday's severe storms.
Weather bureau spokesman Rick Threlfall says Logan bore the brunt.
He says more than 55 millimetres of rain fell in Greenbank and golf-ball-sized hail was reported in Marsden.
"That probably also bought the strongest winds," he said.
"We did have some reports of house and tree damage in Greenbank."
He says conditions will remain unstable across the south-east this week.
"On most of these days there is the potential for one or two severe thunderstorms around, so people making making the preparations around south-east Queensland, everyone should be aware of," he said.
"It's pretty much the peak of the storm season, so as we go through this week we can expect quite a few showers and quite a few thunderstorms as well."
Energex spokesman Danny Donald says crews are still trying to restore power to hundreds of storm-affected properties.
"We've still got around 1,000 customers around Jimboomba, New Beith and Greenbank still without supply," he said.
"These were the worst-hit areas last night and a lot of power lines were ripped down around that West Logan area.
"Our crews have been out there all night and again this morning with fresh crews restoring power."
