Homes have been evacuated, roads have been closed and dams are overflowing as heavy rains continue to fall across southeast Queensland.
Record September rains have continued into October, with parts of the southeast receiving more than 300mm in 24 hours.
Waist deep water flooded yards and inundated homes in Deagon, in Brisbane’s outer north, after a nearby creek peaked around noon (AEST) on Monday.
Twenty people from 15 homes on Henderson and Stockham roads, including one person on a yacht on Cabbage Tree Creek, were evacuated.
“Lowset homes experienced water and mud inundation but nothing was swept away,” a department of community safety spokeswoman told AAP.
More than 50 roads across the southeast region have been closed, including parts of some highways, due to flooding.
Peak motoring body the RACQ said it was facing its busiest day in the region, with all roadside assistance vehicles activated.
A flood warning is current for coastal streams from the Sunshine Coast to the NSW border.
Brisbane’s CBD has been soaked by 92mm of rain in 24 hours since 9am (AEST) on Sunday.
Most parts of Brisbane were drenched in more than 100mm of rain with the heaviest falls of more than 200mm recorded in the city’s outer northern and northwestern suburbs.
Rainfall on the Gold Coast hinterland topped at 315mm, while the Sunshine Coast hinterland north of Brisbane received 150mm.
The unseasonal heavy rain is easing in Brisbane late on Monday, Queensland’s Bureau of Meteorology says.
“The heavy rain will continue to fall north of Brisbane to Caboolture and west of Brisbane out to Toowoomba,” the bureau’s senior forecaster Brett Harrison said.
“Showers will become isolated on Wednesday.”
Southeast Queensland’s three major dams have reached capacity and releases of water began at Wivenhoe Dam, the largest, on the weekend for the first time in a decade.
Somerset Dam is also topping capacity. Many smaller storages are overflowing, adding to the drama of widespread localised flooding.
All major Sunshine Coast dams are currently releasing through their spillways.
