The far north and the west are expected to be the worst-hit areas.
The Bureau of Meteorology (BOM) said these areas of Queensland could see up to 10 times their average falls for May, with totals of 200mm or more expected.
Meterologist Miriam Bradbury told Today that Queenslanders could expect to see the rain increasing from tomorrow but the main period of concern would be between Tuesday and Thursday this week.
“That’s when we’re looking at heaviest falls, with the areas of greatest concern those western and southwestern inland parts of Queensland, also reaching back across to Capricornia Coast as well.”
Some areas could see rainfall totals between 50mm and 150mm each day with possibly higher falls should thunderstorms develop, Bradbury said.
“You’re talking about potentially 300mm of rain, she said.
A number of catchments across south-west Central Queensland were looking at river flooding with roads cut off and some communities still isolated.
“This rainfall that we’re expecting this week does pose a concern for those communities as well as catchments across the east coast which could see renewed river rises as well,” Bradbury said.
“Essentially we’re looking at a renewed risk of riverine flooding across large parts of Queensland with the rain to come.”
On Friday evening, a man was rescued after his car became trapped in floodwaters in the Sunshine Coast hinterland.
