The focus on Sunday will be on the area from Charters Towers to Emerald in northern Queensland.

Weather bureau senior meteorologist Jonathan How urged residents to stay on top of flood warnings.

“At this stage, we’re not expecting widespread flooding but areas of heavy rain with thunderstorms could produce flash flooding as well as rapid rises in creeks, rivers and storm drains,” he said.

On Saturday, wind gusts reached 93km/h at Gympie, while 64mm of rain fell at Cedar Pocket Dam in Queensland.

The Sunshine Coast was also hammered by rain, with Beerburrum recording 110mm in two hours and Landsborough copping 67mm in 30 minutes.

About 28,000 people were still waiting for power to be reconnected, predominantly in the hardest hit areas of the Gold Coast, Scenic Rim and Logan, after storms battered the region late on Christmas Day.

Severe weather between Christmas Eve and Boxing Day resulted in 10 fatalities in Queensland and Victoria, among them a nine-year-old girl lost in a stormwater drain.

NSW State Emergency Service Crews were kept busy, responding to 473 calls for help and conducting six flood rescues across the Christmas weekend.
