An extreme heat warning covers the state of Victoria, with severe and extreme heat expected to peak on Tuesday and Wednesday. High daytime temperatures and hot nights make it harder for the body to cool down, raising the risk of heat illness. Several other states and territories including New South Wales, the Australian Capital Territory, Queensland, South Australia, Tasmania, and the Northern Territory are also under severe heatwave warnings. Meanwhile, at least six major bushfires are burning across Victoria. Fire officials have issued watch and act warnings for many areas due to the hot, dry, and dangerous weather conditions during the long weekend. Residents are urged to stay alert and monitor updates closely.
