The latest seasonal outlook from the Bureau of Meteorology shows a strong chance of a warmer and wetter summer in parts of a Australia, but the drought-ravaged Murray Darling only has a 50-50 chance of above average rain.
The Bureau's national outlook for temperatures over the November to January period shows a moderate to strong shift in the odds favouring warmer than normal conditions over eastern Australia.
It reports that the pattern of seasonal temperature odds across Australia is mostly a result of continued warmth in the central to southeastern Indian Ocean, especially off the west coast of WA, which is also driving the rainfall outlook.
The chance of exceeding the median maximum temperature for the November to January period is between 60pc and 70pc for Tasmania, Victoria, NSW, Queensland, eastern SA and the north and east of the NT (see map).
The odds of above median maximum temperatures increase to 70-75pc over the Queensland Gulf Country. But across the rest of the country, including WA, south western NT and western SA, the chances of a warmer than average November to January period are between 40pc and 60pc, indicating roughly equal chances of warmer or cooler than normal conditions.
As for minimum temperatures, the chance of exceeding the median minimum temperature for the November to January period is greater than 60pc across nearly all of Australia, except WA.
The odds increase to 75-80pc over parts of eastern Queensland, southwest NSW, western Victoria and southeastern SA (see map).
Northern and western Australia has the best chance of receiving wetter than normal conditions over the November to January period.
The chance of exceeding median rainfall over Australia is between 60pc and 70pc for most of the NT, northern and western Queensland, the Kimberley and adjacent northern interior of WA, and the Gascoyne and southwest districts of WA (see map).
The odds rise to 70-75pc in a few small areas over the Kimberley and northern NT.
But across the rest of the country, the chance of exceeding the median rainfall for the November to January period is between 40pc and 60pc, meaning that above average falls are about as equally likely as below average falls in these regions.
