These thunderstorms are forming over the Qld-NSW Interconnector (QNI) which is likely to impact the transmission capacity between the two states on Wednesday afternoon.
As of 3:30pm, a severe thunderstorm warning is current for very dangerous storms which are likely to produce large, possibly giant hailstones and damaging winds across southern and central Qld. Over the border in NSW, a thunderstorm warning has been issued for heavy rainfall, large hailstones and damaging winds about the Northern Tablelands and North West Slopes.
These thunderstorms have the potential to continue into Wednesday evening, before the risk eases in some areas on Thursday. While storms should clear NSW on Thursday, Qld could see severe thunderstorms develop in central and northeastern Qld on Thursday, with the potential for damaging wind gusts.
