JEFF Higgins from Higgins Storm Chasers has updated the storm supercell warning to include both Friday and Saturday.

Mr Higgins said he wanted to be sure of the data before upgrading the warning for Saturday but said now anywhere east of the trough or storm line was "on".

The fulltime storm chaser said the supercell will start inland in Central Queensland and will most likely steer towards the coast, bringing with it some very "nasty" aspects.

"With supercells the threats are more likely with all the nasty things like hail being 100 percent inside the core of the supercell," he said.

Mr Higgins has been tracking the storm for the last ten days and decided to issue a warning for the supercell only once he was 90 percent confident of it happening.

"The issue is with the surface trough position which is now positioned inland of the Darling Downs and extends through to Emerald and that's why we've issued the warning for Central Queensland," he said.

"It's slowed down and is expected to steer towards the coast and stall and won't push off the coast which is why we've extended the warning to Saturday."

Mr Higgins said he wanted to be sure of the data before upgrading the warning for Saturday but said now anywhere east of the trough or storm line was "on".

However, he said because of the accuracy of his modelling, he couldn't guarantee that a supercell would hit Gladstone.

"What we can say is that there will most likely be severe thunderstorms and supercells are usually within 100km of them," he said.

"At this stage it could hit 20kms south of Gladstone or 50kms inland.

"We just don't know but what we can say is that it may hit within 100kms if it does," he said.

Mr Higgins will be at the Sunshine Coast and Bundaberg over the next two days chasing the storm.

He said a love of photography was what propelled him to become a storm chaser.

"I'm not too worried if we get it wrong because we're just following what's happening," he said.

"People get excited and Queenslanders seem to hang out for it but it's hard for us to be excited when people's roofs are getting blown off."
