Torrential rain is now hitting south east Queensland, with authorities issuing alerts for residents in the Lockyer Valley and Toowoomba Regional Council areas, as creeks and rivers start to rise quickly.
"Multiple roads are currently being impacted by flooding and road closures are in place," the Lockyer Valley warning said.
People have been urged to stock up on enough supplies to last three days amid fears homes may become isolated.
A major flood warning is current for Warrill Creek, with moderate flooding in the Bremer, and Laidley Creek and lower Brisbane River.
While conditions are not expected to replicate the disaster earlier this year, the Bureau of Meteorology said rain was expected to continue over coming days, with the possibility of more intense falls in saturated catchments, thunderstorms and damaging winds.
According to Higgins Storm Chasing, the upper low is properly into south west Queensland now, and will head east over the next 24 to 48 hours and continue to suck big moisture in from the Coral Sea.
Toowoomba Regional Council advised there was no immediate risk to the Oakey township from water spilling over the Cooby Dam wall.

"Council's water operations centre is monitoring the region's three dams around the clock and will provide updates as required," Mayor Antonio said.
"Council on Thursday started contacting property owners who are directly downstream of Cooby Dam.
"We are continuing to update these residents in line with our emergency action plan, along with residents downstream of Cressbrook and Perseverance dams."
