Australia’s east coast has been warned to brace for large hail and strong winds as thunderstorms hit Victoria, NSW and Queensland, potentially creating ‘very dangerous supercells.’
The most powerful storms so far this season will form on Thursday morning in the ranges and move to the coast by the afternoon, lashing the region from eastern Victoria to central Queensland with intense rain, Weatherzone Meteorologist Graeme Brittain told Daily Mail Australia.
‘We’re potentially going to see winds in excess of 80km/h, large hail is also a possibility, as well as localised flash flooding,’ he said.
The storms may create the perfect environment for dangerous supercells to form, Mr Brittain confirmed.

Tom Saunders, meteorologist for Sky News, said there were three ingredients necessary for a thunderstorm, and all three would be present on Thursday.
Mr Saunders said the secret ingredient which made thunderstorms severe, called wind shear, was also present.
Wind shear is the difference in wind speed and/or direction over a short distance.
High wind shear can rotate storms, causing them to become more powerful and dangerous.
The meteorologist said it is very likely wind shear could play a part in creating supercell storms on Thursday.
Sydney, Canberra and Brisbane should prepare for damaging winds more so than heavy rainfall, forecaster James Thompson, with the Bureau of Meteorology, told ABC
‘Probably the worst of it is east of Roma to Goondiwindi, across into the Brisbane region in the afternoon, and anywhere really south of Bundaberg,’ he said.
‘So one or two places might get 50-plus millimetres but mostly a lot less than that.’
The thunderstorms could bring 80km/h winds, hail larger than 2cm and localised flash flooding
On Tuesday, BOM said there was a good chance of a La Nina weather pattern, which could bring intense rain, storms and cyclones throughout the summer months

Mr Saunders also predicts a supercell storm could hit the two major cities on Thursday
Experts predict the south-east parts of the country will receive above average Summer rainfall
‘Instability and shear levels on Thursday look sufficient for supercell development across south-east Queensland, and along the northern and central NSW coast and adjacent ranges,’ he said.
Mr Saunders said weather should return to normal by Friday, but storms could be in the works from Saturday to Monday.
On Tuesday, BOM said there was a good chance of a La Nina weather pattern, which could bring intense rain, storms and cyclones throughout the summer months.
‘The chance of a La Niña forming in late 2017 has increased. Chances are now around 50 per cent – twice the normal likelihood,’ the Bureau said.
