Southern and eastern Australia is about to cop a lashing from Mother Nature, the Bureau of Meteorology (BoM) advises, with falls of up to 200mm predicted in parts of Victoria and western NSW.

Severe thunderstorms are expected in South Australia late on Thursday and into Friday, bringing with them damaging winds, hail and heavy rainfall up to 100mm.

As the system moves into Victoria and NSW, that predicted rainfall only gets higher.

“The system will ramp up over Victoria and western NSW on Friday and into Saturday with rainfalls of 100-200mm expected in these areas, particularly those areas closer to the ranges,” BoM senior forecaster Scott Williams said.

“Peak falls in the northeast of Victoria could top 300mm over the 48 hours to Saturday night.

Initial Flood Watch issued for Victoria: From Friday to Sunday widespread totals of 60-120mm in the South and 100-200mm in the North are forecast. Widespread flooding is likely from Friday onwards. Check here for updates https://t.co/Ildo3KSAXKpic.twitter南京夜网/arHidYCYGu
