UPDATED 2PM:
THE Weather Bureau has forecast another wave of storms and rain this afternoon and tomorrow which may produce life-threatening flash flooding in the south-east, Darling Downs and Granite Belt.
A bureau spokesperson said six-hourly rainfall totals of 50mm to 70mm were likely, with locally heavier falls possible from storms.
Flash floods were expected to develop.
"The situation is likely to pose a serious risk to already affected and flooded areas. In some areas, the situation may become life threatening," the spokesperson said.
Places likely to be affected include Brisbane, Gold Coast, Warwick, Thargomindah, Toowoomba, Brisbane, Dalby, Maroochydore, Roma, Charleville, Birdsville, Emerald, Stanthorpe, Goondiwindi, Coolangatta and Ipswich.
EARLIER:
THE south-east copped more wild weather on the weekend, with flash flooding and hundreds of calls to emergency services as more than 100mm fell in some spots in the Redlands, Logan and Scenic Rim.
North Tamborine was among the hardest hit, copping 263mm in 24 hours.
The Leslie Harrison dam is at its highest level since records began in 2016, with Seqwater urging residents to avoid potential hazards downstream as the dam reached 111 per cent capacity.
Moogerah Dam in the Scenic Rim remains below 15 per cent, only copping about 40mm.
QFES swiftwater crews conducted six swiftwater rescues in the south-east overnight, including on Brisbane's north and at Willowvale, Springbrook and Tallebudgera.
Fire and Emergency Services Minister Mark Ryan urged people to heed the warnings from agencies including the weather bureau as rain caused flash flooding across the region.
Sandbagging stations were opened today, with rain set to continue until mid-week.
Residents could pick up sandbags at Cleveland, Dunwich and Russell and Macleay islands in the Redlands, or the Logan East SES depot at Daisy Hill.
Beaudesert is set to cop rain until Wednesday, with the wet weather and flooding on the Gold Coast causing the final pig and calf sale scheduled for Monday to be postponed until next week.
The region could get up to 80mm of rain tomorrow, while up to 70mm is forecast to fall at Jimboomba.
The Redlands is likely to receive up to 50mm.
Showers are set to clear on Thursday, but rain could return on the weekend.
Transport Minister Mark Bailey said with the forecast of more rain over the coming days, drivers needed to exercise caution.
"No destination warrants taking an unnecessary risk that leads to tragedy," Mr Bailey said.
"Before you head out onto the road with family and friends, look at the forecast and plan your drive.
"If you can, avoid driving until the weather clears up, and if you get caught in a quick moving storm or rain event, drive to conditions and pull over if you think it's unsafe.
"We want every Queenslander to get to their destination safely."
