Central Queensland supercell storms possible: BOM

METEOROLOGIST with the Bureau of Meteorology David Grant says the upcoming weather events over the weekend are unusual for this time of year.

Mr Grant said due to the "unsettled" weather pattern over the next few days, he could not rule out the chance of a thunderstorm.

"There is quite a decent risk of severe thunderstorm activity but they can usually be very hit and miss… rainfall is usually quite isolated and not over widespread areas," he said.

"I would say (Central Queensland will see) totals of at least 75mm over the next few days which can cause flash flooding.

"We can get tropical rainfall but this is something we usually see in October and November, so it is unusual."

Mr Grant said the weekend event could involve hail in addition to heavy rain and winds.

STORM RISK: Hail, heavy rain and destructive winds are forecast by Higgins Storm Chasers for this weekend.

BOM's Queensland thunderstorm forecast for the next two days was then released yesterday afternoon, which spelled out the possibility for "supercell" storms late this afternoon.

Supercells are "highly organised, long-lived" thunderstorms which can produce damaging to destructive winds, large to very large hail and extremely heavy rainfall leading to flash flooding.

Later in the evening, storms could merge to produce more of a "sudden, violent localised" storm line as it approaches the coast.

In this event, the risk of hail would be lessened but the risk of damaging winds and a short burst of very heavy rainfall would increase.

The bureau's website also predicted a very warm week ahead for Rockhampton, with temperatures expected to top 37 degrees from today until Wednesday.

Qld Fire and Emergency Services officials have backed-up warnings to be prepared for severe storm activity across the state over the next few days.

A post on the QFES official Facebook page urged residents to prepare by staying up to date via radio or television, and to reduce storm damage by visiting the Get Ready website.
