Heatwave in some areas, flood warnings in others

The heatwave in western Queensland is business as usual for residents and unlikely to topple records, a weather forecaster says.

Michael Knepp from the Bureau of Meteorology said Birdsville near the Northern Territory border hit 45C on Friday and did not drop below 30C overnight.

Temperatures are expected to stay in the mid-40s for about a week. Mr Knepp said the high temperatures were four to five degrees above average for this time of year but were "not out of the ordinary".

"To be fair it's not much of a heatwave, it's a low intensity heatwave," he told AAP on Saturday.

"It's not unusual for them to get temperatures in the 40s for many days in a row.

"They're used to it out there."

Mr Knepp said the heatwave was unlikely to smash the 1972 record of 49.5C, which was recorded on Christmas Eve.

Elsewhere in the state, a number of flood warnings sparked by heavy rainfall from ex-tropical Cyclone Penny, which has now dissipated, have been lifted.

A moderate flood warning remains in place for the Connors and Isaac Rivers in central Queensland, with both expected to peak on Saturday afternoon.

Mr Knepp said it was "very quiet weatherwise" across Queensland with only a few isolated storms expected around Cape York on the weekend, and a few scattered showers on the east coast.
