Up to 45 millimetres fell within an hour in Queensland's Darling Downs this morning with large hail and damaging winds possibly arriving in the state's south-east this afternoon.
Thunderstorms have eased and are now confined to the Main Range in the Darling Downs and Scenic Rim after an earlier severe storm warning, the Bureau of Meteorology (BOM) said.
Severe storms are possible again this afternoon in the Darling Downs, Granite Belt, South Burnett and south-west including Brisbane and the Gold Coast later this evening.
BOM said there was a risk of heavy rain, flash flooding, damaging winds and large hail.
Already there have been isolated downpours with 45 millimetres recorded within half an hour at Torridon about 7am.
"Even the surrounding weather stations have had 30 to 37. We are recommending everyone to keep an eye on the radar and drive safe today because there might be some flash flooding," Brooke Pagel, duty forecaster said.
Ms Pagel said rainfall was unlikely to be widespread.
"Even though these cells are moving east, Gold Coast hinterland and Scenic Rim where it will be tracking north mid-afternoon tomorrow," she said.
She said it had been "very unsettled weather" the past couple of weeks, with temperatures sitting 1 to 2 degrees above average as trough systems moved around Central Australia — but nothing record breaking.
