The Bureau of Meteorology has issued a severe-weather warning for Victoria. An “unprecedented” three days worth of rainfall, and thunderstorms, could lead to flash floods throughout the state.

It looks like western Victoria will be hit today. The storm is predicted to then move to Melbourne tomorrow night and last into Saturday.

Up to 300 millilitres of rain is expected from the storms, a stark contrast to the 30-degree temperatures of this week, the longest November heatwave in more than 150 years. November usually sees up to 100 millilitres of rainfall during storms.

Areas most likely to be affected include Melbourne, Geelong, Mildura, Horsham, Warrnambool, Bendigo, Shepparton, Seymour, Maryborough, Ballarat, Wodonga, Wangaratta, Traralgon and Bairnsdale.

The bureau has warned people to pay attention to storm warnings and avoid any floodwaters or swollen rivers.

And probably best to bring your strongest umbrella with you this weekend.
