Bundaberg has received more than the monthly average rainfall for August within a day.
44.2mm was recorded on Tuesday, August 13, the town usually sees a total of 32.5mm for the month.
Surrounding areas saw the heaviest totals though with 140mm at Mount Rawdon, near Mount Perry.
The system has started tracking south and the rain is expected to ease into showers throughout Wednesday.
Police are asking motorists to use common sense while driving on the wet roads.
Inspector Gareth Bosley says unfortunately accidents tend to happen more in wet conditions.
“Slow down, drive to the conditions, allow further distance between you and the car in front and if your visibility is reduced pull over where it’s safe to do so and wait for the rain to pass,” he says.
Three serious incidents occurred on the region’s roads on Tuesday.
A man in his 20s was seriously hurt in a crash at Lowmead, taken to Bundaberg Hospital then flown down to Brisbane.
Around 11am another man crashed into a power pole at Thabeban and suffered life-threatening head injuries.
