UPDATE 10.30am: A Bureau of Meteorology forecaster has said the key message for the public is to keep an eye on any possible warnings on the BOM website.

She said the peak time for thunderstorms was generally late afternoon and into the evening.

The forecaster said the storms, expected to bring flash flooding, damaging winds and hail to parts of Queensland including the Wide Bay, are moving towards the coast from the west.

"There is a significant risk of severe storms today (Friday) including areas of the Wide Bay," she said. 

While storms can't be ruled out throughout the day, the forecaster said they're more likely to hit later Friday afternoon and into Saturday.

The SES is urging residents to take precautions seriously and to ensure any loose items like chairs and trampolines are secured and gutters are cleared.

 "Clear your gutters, or else the rain can back up, enter your roof and your roof can collapse from the inside," SES group controller Bob Biram said. 

THURSDAY 7.10pm: ONLY hours before severe storms and possible supercells are expected to hit the region, Fraser Coast SES group controller Bob Biram said now was the time for people to get ready for all possibilities.

"Have a look at what you've got in your yard; trampolines love to dance across properties during storms," Mr Biram said.

"Clear your gutters, or else the rain can back up, enter your roof and your roof can collapse from the inside."

He said finding a space undercover for vehicles could also save people heartache in the future.

"Either park the vehicle under cover or secure a tarp over it to prevent possible hail damage or damage from other debris."

UPDATE 2.24pm: PEOPLE planning to travel to or from remote parts of the Fraser Coast are warned roads could be submerged by flash flooding and areas are likely to become isolated if Friday's predicted supercell storm hits the region.

Fraser Coast disaster management coordinator Mal Churchill said people living out of town should now be stocking up their pantry to ensure they are ready for potential isolation.

"We are in the storm season, [isolation] can happen at any time, if you go down and buy few extra tins right now, and you don't get stuck you have them for later," Mr Churchill said.

"It's about having available to you the normal supplies you and your family need."

He added people should check to make sure their neighbours were prepared.

"Especially if they're elderly," he said.

"It might be harder for them to get down to the shops for supplies."

EARLIER: THE Bureau of Meteorology has confirmed flash flooding, heavy rain and damaging wind gusts can be expected in parts of the Fraser Coast on Friday and Saturday.

On Thursday, the popular weather blog Higgins Storm Chasing announced supercell storms would be hitting the region on Friday, and warned people living in the area to prepare for 8cm hail stones, flooding and frequent lightning.

Preparing an evacuation and emergency kit

Meteorologist on duty and BOM spokesman Gordon Banks said thunderstorms did not have to be supercells to be severe.

"We think there's going to be a pretty active outbreak of storms through Friday especially and Saturday," Gordon said.

"There is some potential for some supercells in the area."

He said because of the nature of the storms, it was hard to predict how much rain the entire region would receive.

"There is certainly a risk of flash flooding with individual thunderstorm cells that bring very high rainfall rates- even over an hour you could get falls in excess of 50mm which could certainly generate some flash flooding," he said.

"More generally, I think we'll have to see how things pan out, it depends on which way the storm cells move."

He said some areas could receive up to 100mm of rain, while others may only receive 5mm.
