Queenslanders are being told to brace for “life-threatening” flooding, as the already soaked southeast could be pelted with another 150mm on Tuesday.
At 4.30am, the Bureau of Meteorology issued a warning for the southeast, saying heavy rainfall which may lead to flash flooding is likely around the Darling Downs and Granite Belt, and Southeast Corner on Tuesday, continuing overnight into Wednesday morning.
“The situation is likely to pose a serious risk to areas already affected by heavy rainfall, including the risk of landslips in steep terrain,” the warning said.
“In these areas, the situation may become life-threatening.
“Six hour rainfall totals of 100-150 mm are likely, and locally heavier falls are possible with thunderstorms.”
It comes after the state was drenched with heavy rainfall on Monday night, including at North Tamborine, where 213mm has fallen since 9am Monday.
Upper Springbrook recorded 191mm in the same time period. Further east on the Gold Coast, Hotham Creek recorded 170mm. At North Stradbroke Island, 196mm was recorded.
Meanwhile, the Maranoa and Warrego districts are also bracing for heavy rainfall on Tuesday, which may lead to flash flooding.
Six-hour rainfall totals of 50-70 mm are likely, and locally heavier falls are possible with thunderstorms.
Areas likely to be affected include Brisbane, Ipswich, Gold Coast, Toowoomba, Warwick, Stanthorpe, Kingaroy, Dalby, Goondiwindi, Roma, Charleville and St George.
A separate flood watch is current for southern parts of Queensland, stretching all the way from the South Australian border to the southeast.
While the coastal convergence is weakening on Tuesday, a new system coming from the west will be responsible for hitting the soaked state with more rain.
On Monday, Premier Annastacia Palaszczuk pleaded for Queenslanders to stay off the roads.
“We want everyone to be on alert over the next 24 hours,” she said on Monday.
Emergency Services Minister Mark Ryan said it wasn’t worth the risk.
“We are in a situation at the moment where very heavy downfalls of rain are occurring in very short periods of time, which is leading to dangerous situations arising very suddenly,” he said.
The SES has received more than 520 call-outs since Monday morning.
