Triple threat storms are expected to ravage southeast Queensland and northern NSW on Tuesday and Wednesday, as forecasters warn this is a taste of what summer will look like.
The Bureau of Meteorology is forecasting severe to dangerous thunderstorms for Queensland and NSW on Tuesday and Wednesday with large to giant hail, damaging to destructive winds and heavy rainfall which could cause flash flooding.
It comes after wild weather lashed the east coast over the weekend, which saw a Brisbane woman to be hospitalised after a tree fell on her car and hailstones the size of golf balls fall on parts of the country.
The Bureau of Meteorology also recorded more than 2.24 million lighting strikes across the country over the weekend.
Southeast Queensland will likely bear the brunt of Tuesday’s wild weather, with residents in Brisbane, the Gold Coast, Darling Downs, Wide Bay and Capricornia all being warned to keep a close eye on storm warnings.
The storm activity will likely move into northern NSW on Wednesday, especially around Armidale, Coffs Harbour and Port Macquarie.
Bureau of Meteorology forecaster Jonathan How said on while there were no warnings current on Tuesday morning, the conditions were ripe for widespread activity later in the day.
“All the ingredients are there for severe storms,” he said.
“Those storms are likely to turn severe or dangerous for southeast Queensland on Tuesday.
“NSW will have their day on Wednesday, when we will see very unstable conditions extending into the northeast of the state.
“We’ll see quite widespread thunderstorm activity across the northeast, extending down into central parts of NSW, but the most severe will be in the northeast.
“East to southeast Queensland should also expect a dangerous storm on Wednesday.”
Severe thunderstorms would mean damaging winds in excess of 90km/h, large hail stones of around 2cm and heavy rainfall, whereas dangerous storms would result in destructive winds in excess of 100 km/h, and giant hail stones of 5cm, as well as heavy rainfall likely to lead to flash flooding.
“That’s all a possibility,” Mr How said.
Severe to dangerous thunderstorms could continue to lash the east coast for months, as La Nina conditions set in.
“We should absolutely expect more, we’re just starting the thunderstorm season, getting to peak in the east,” Mr How said.
“We’ll see more of these events over coming weeks and months particularly now we have a La Nina.”
Offshore, there are no marine warnings current for Queensland, but central NSW has a hazardous surf warning.
“That includes Sydney, Port Macquarie and Warra, there’s a pretty big swell,” Mr How sad.
“Out in the water today there’s also a strong wind warning.”
