The river is also rising at Gregor Creek, and could burst its banks.“Over the next three or four days, there could be widespread falls of 50 millimetres to 100mm and isolated falls up to an exceeding 250mm,” Dean Narramore from the bureau said.Elsewhere, relief is arriving for some sunbaked Australians after several states sweated through one of the hottest December days in years.Parts of Queensland, Victoria, NSW and South Australia topped 45C on Monday, while the Northern Territory faces severe to extreme heatwave conditions for much of the next three days.“It’s very hot out there,” Narramore said.Queensland’s Urandangi recorded a maximum of 46.4C.Extreme fire danger warnings remain in place with high bushfire risks expected across Australia’s south-east.Mount Lofty Ranges in eastern South Australia and most of western and central Victoria, including Melbourne, are under extreme fire danger warnings.“These hot, dry, windy conditions are likely to lead to extreme fire dangers,” Narramore said.“That means that if fires do get going in this weather, they’re likely to be uncontrollable and uncontainable.”Alice Springs reached 41.9C just before 3pm, before the mercury fell 15C in just over 90 minutes.Melbourne fell short of its forecast high of 41C, with the temperature topping out at 39.4C.A cool front reached Adelaide and western Victoria by 2pm on Monday but the heat will remain for the rest of the week in Queensland and the NT.AAP
