Thursday's storms becoming severe in eastern Australia

Ben Domensino, Thursday January 16, 2020 - 14:12 AEDT

Severe thunderstorms are developing over parts of eastern Australia this afternoon, with warnings in place for heavy rain, damaging winds and large hail.

A low pressure trough over Australia's eastern inland is triggering showers and thunderstorms in parts of NSW, the ACT and Queensland on Thursday.

At 2pm AEDT, the most intense storms were occurring over the eastern half of NSW, with a severe thunderstorm warning in place along most of the slopes and ranges, including the ACT, and parts of the coast.

Some of the intense thunderstorms produced one-hour rain rates of 53mm at Barrington Tops and 35mm at Blaney around midday. This rain is heavy enough to cause flash flooding, particularly in areas recently affected by bushfires.

Burnt out bushland can exacerbate flash flooding due to increased surface runoff in the absence of thick vegetation. Debris such as ash and branches can also make floodwaters more damaging and lead to blocked drains and waterways.

Thunderstorms were also increasing over parts of Queensland and northeast Victoria on Thursday afternoon, with severe storms possible in both states.

Keep up to date with the latest severe storm warnings in eastern Australia during the rest of Thursday.

A very wet weekend for southeast Qld, northeast NSW

11:48 AEST A prolonged rainfall event is set to bring large totals to parts of NSW and Qld from Saturday, with possible heavy falls and flooding. A low-pressure system in the Coral Sea, a deepening coastal trough and persistent easterlies will bring moisture-laden air into southeast Qld and northeast NSW will bring days of rainfall to the region. While there is not a drop of rain on the radar over southeast Qld and Northeast NSW on Friday morning, the mass of cloud associated with a low in the Coral Sea will enhance rainfall over the weekend.
