Storms are likely to develop over central and eastern Victoria and most of the eastern half of NSW, including the ACT but exlcudung the state's far northeast. Severe thunderstorms are possible across this broad region, with damaging winds, large hail and heavy rain all a risk. 

While the Great Dividing range will be a focus for much of Tuesday's thunderstorm activity, showers and storms will also occur in northern Victoria and in central western and northwest NSW. Melbourne, Canberra and Sydney are also at risk of severe storms, most likely in the afternoon or early evening.
