In addition, the heavy downpour is also anticipated to cause renewed riverine flooding across many rivers already flooded in southern Queensland, New South Wales, and Victoria. In its media release on Thursday, the BoM hinted it may issue severe thunderstorm warnings for parts of Queensland and New South Wales soon.

As the country's spring approaches this September, the severe weather and torrential rain will apparently be the first during the current season. Similar phenomena have transpired during the winter season of Australia from June to August. Rainfall accumulation could reach up to 50 mm., especially when under thunderstorms. As a result, widespread rainfall between 15 and 30 millimeters is likely across inland New South Wales, northern Victoria, and southern Queensland.

The Bureau attributes the weather phenomenon to an ongoing cold front associated with a low-pressure system over Australia.

Riverine flooding is possible for areas near bodies of water, including rivers and streams. While there have been no immediate reports of significant disruption, a mild to moderate wet weather is possible in the said Australian states in the coming hours. The BoM warns the thunderstorms will be severe, producing heavy rainfall and lead to flash flooding, as well as damaging winds and potential large hail. This is according to the country's Bureau of Meteorology (BoM) which on Thursday, September 8, said the weather events will occur in parts of Queensland, New South Wales, and Victoria. Rain and isolated thunderstorms are expected to transpire in eastern and southern Australia until Friday, September 9, and Saturday, September 10, where it will gradually ease.
