Yesterday, Miriam Bradley from the Bureau of Meteorology said the storms have the potential to be "severe".
Ms Bradley said the storms could "produce damaging wind gusts, heavy rainfall that could lead to flash flooding or large hail".
"All of those are quite significant risks. The damaging winds can bring down powerlines and trees and cause other damage.
"The heavy rainfall can lead to flash flooding and make hazardous driving conditions and even just conditions for being outdoors.
"It is definitely very important to stay aware of the risks and the forecast for your area."
