Totals in excess of 200mm were possible in areas spanning from Tully to Ayr, south of Townsville, before additional rainfall blankets the region through Monday.
The Bureau of Meteorology warned a strengthening monsoon trough lingering across northern parts of Queensland will drive the intensification of rainfall in tandem with a tropical low off the coast.
It comes following a week of wet weather that cut power to communities, forced hundreds to evacuate and required the Australian Defence Force to erect a temporary bridge near Ingham for critical supplies.
A number of flood warnings remain in place through the weekend with river systems and catchments likely to respond, the bureau warned.
The tropical low off the coast has a small chance of developing into a tropical cyclone and is expected to move east away from the coastline.
"Moving into Sunday we'll see that low slowly moving away with the heavy rainfall continuing about coastal areas," Meteorologist Sarah Scully said.
"It's not really until Monday that it really starts to scoot away, dragging with it the heavier rainfall with that lowering to below the severe weather warning threshold."
The Whitsunday Coast airport cancelled all flights on Friday due to forecast heavy rainfall.
High weekend totals and another severe weather warning is a hammer blow to residents who have begun returning to their inundated homes.
Personal belongings, vehicles, farming equipment and homes have been decimated by flash flooding.

At the city's main beach, a yacht broke its moorings and washed ashore during the wild weather.
Disaster payments have become available for affected residents, with Prime Minister Anthony Albanese announcing an $8 million community relief fund.
Mr Albanese and Queensland Premier David Crisafulli met with locals and army personnel when visiting the region this week.
The damage bill for north Queensland remains to be seen but insurers have received over 4000 storm and flood related claims with further expected.
Residents in north Queensland are urged to monitor the latest bureau warnings and updates from emergency services.
