“In particular, tomorrow, it looks like a very potent set up for severe thunderstorms to occur,” she said.
Thunderstorms on Saturday may include more destructive winds, giant hail exceeding five diameters, and more intense rain bringing with it the risk of flash flooding.
Wong noted that in 2020, south-east Queensland was hit by 14-centimetre hailstones on Halloween.
“It’s just worth noting that giant hail could be a lot bigger than five centimetres, and it has occurred this time of year in our part of the world,” she said.
It is difficult to predict how the storms will compare to last weekend’s weather, Wong said.
“It’d be probably unlikely to see exactly the same areas being impacted exactly the same,” she said.

“Some areas that missed out last time may see some storm activity tomorrow, or ones that saw storms last time, they may see storms again tomorrow.”
The bureau cannot completely rule out the possibility of tornadoes at this stage, as the conditions may be in place to see them form in areas including the South Burnett and Sunshine Coast Hinterland where there is higher terrain.
“What we really need is a thunderstorm to occur, that thunderstorm to become severe, that thunderstorm to become a super, severe thunderstorm, and then also produce a tornado,” Wong said.
Wong urged people to prepare themselves and their property for storms and to stay safe.
“Do what you can to prepare yourselves and your property ahead of the storm activity that we’re expecting over the next couple of days,” she said.
“Consider tying down loose items in the yard and things like that that might become projectiles if the wind really does pick up with the storms and maybe consider your activity that you’ve got planned over the next couple of days as well.”
