More intense storms are forecast to hit south-east Queensland on the weekend, just days after the region endured several deadly weather systems, including a "mini cyclone".

The Bureau of Meteorology warns storms are on the way for Central Queensland, the Sunshine Coast and Moreton Bay while the rest of the state is set to swelter in a heatwave.

Temperatures in the south-east are expected to reach the mid-to-high thirties today, up to eight degrees higher than the December average.

The warmest part of the state will be Winton in the central-west, with a top of 44C.

“We’ve had the fires already. We’ve had heat already, had a cyclone and now the thunderstorms then back to the heat again,” BOM forecaster Steve Hadley said.

Time to move to Adelaide.
