Summer temperatures are expected to rise above average, causing fresh warnings of fires and heat waves.
Recent prospects of the Bureau of Meteorology suggest that most of Australia has a chance of 80 percent of normal temperatures between December and February.
Meanwhile, the possibility of forming El Nino in 2018 and creating conditions in eastern Australia still dry and hot now stands at 70 percent, roughly three times more than the usual risk.
"We have already seen extremely hot temperatures across parts of northern and central Queensland in recent days and this should act as an important reminder of the types of conditions that can be obtained during the Australian summer," the long-range forecasting head of the Long- Dr. Andrew Watkins, on Thursday.
The forecast of a long, hot summer has increased the chances of Australia to record one of the warmest years, by doubling and predicting sticky nights.
Rainy sky and dry soils are expected to result in high temperatures in the city, with more "short, sharp" heat waves than the usual in the southern parts and prolonged heat waves in Sydney and Brisbane, Dr. Watkins told reporters.
"Heat waves are actually our biggest killer when it comes to natural disasters," he said.
The summer outlook also triggered a warning of the increased risk of forest fires across southern Australia.
While some of the eastern sushi-affected countries enjoyed some recent rains, the NSW coast experienced heavy rains during a storm this week, experts say, it will not be long before hot summer temperatures dry up the country's vegetation.
"The potential potential for fire remains throughout major parts of southern Australia," the Center for Research Center for Fires and Natural Disasters reported in its seasonal forest fires, published on Thursday.
The Bureau of Meteorology predicts a lighter summer for larger parts of Queensland, Western Australia and the Northern Territory.
"With this, locally strong rainfall, similar to what we saw in NSW in the past two days, is always possible in the summer, no matter what the prospect shows," said Dr. Watkins.
New South Wales saw its eighth-strongest and fourth-strongest in April-November, while Queensland and Victoria experienced similar conditions.
The dry, warm weather that stretched from autumn to spring now arouses expectations of a near-normal risk of fire this summer for much of Queensland, New South Wales, AST, Victoria, Tasmania, South Australia and Western Australia.
CRS for fires and natural disasters said it took several months above average precipitation to improve the general drought in the landscape.
"The dry landscape means that all hot wind conditions are likely to see an increased risk of fire," the statement said.
"The recent rainfall was not significant enough to drastically change the burden of vegetation (fuel), with many southern and eastern areas already being cured or carrying small grass growth."
