The forecast through September indicates mild water deficits in much of Australia with more intense anomalies in Tasmania, surrounding Melbourne, in the eastern Murray-Darling Basin, and reaching north to the Darling Downs and Brisbane. In New Zealand, deficits are forecast on North Island. Extreme to exceptional deficits will persist in New Caledonia.

The forecast through June indicates that the exceptional water deficits that have dominated much of Australia in prior months will nearly disappear, though intense anomalies are forecast in the north. Primarily moderate deficits are expected from Adelaide through Victoria and along rivers in the Murray-Darling system. Deficits are expected to be more intense in northeastern New South Wales, Tasmania, the southwestern tip of Western Australia, New Zealand, and New Caledonia.
The forecast through March indicates that the intense water deficits that have dominated many parts of Australia in prior months will diminish considerably. However, severe to exceptional deficits will persist in Tasmania; along the southeastern coast of Australia from Adelaide past Melbourne; in the Strzelecki Desert in northwestern New South Wales; around Darwin in Northern Territory; and in the Blackwood River region near Busselton in the tip of Western Australia.
Moderate water deficits, punctuated by more intense pockets, are expected across a large portion of the east and southeast including the Murray-Darling Basin, scattered across the north, and in the southwest tip of the country. Deficits are expected to be intense in Tasmania, pockets along the southeast coast, the southwest tip, Darwin and the Daly River region, and along the southern shore of the Gulf of Carpentaria. Intense deficits are forecast for New Caledonia.
A transition away from significant water deficit is forecast for mainland Australia. Exceptional deficits will shrink considerably, retreating to Channel Country in central Australia. However, intense deficits are forecast for western Tasmania, coastal Victoria, Darwin, and the southeastern tip of Western Australia. Moderate deficits are forecast for the remainder of New South Wales, much of South Australia, Northern Territory, and much of the northern half of Western Australia. Moderate deficits are forecast for North Island New Zealand, and New Caledonia.
Widespread, exceptional water deficits observed in recent months in Australia are forecast to nearly disappear, though intense deficits will persist in Tasmania and near Busselton, WA. Through April, primarily moderate deficits are forecast from the Eyre Peninsula in South Australia through much of Victoria and into New South Wales; for central Queensland to the Gulf of Carpentaria; and, northwest to Darwin, where deficits may be more severe. Deficits are expected to retreat significantly in New Zealand, but will continue to emerge in New Caledonia.
Exceptional water deficits observed in recent months over much of Australia are forecast to diminish considerably in the near-term and through May 2018. However, severe to exceptional deficits are forecast to persist through February in Tasmania and the southernmost tip of Western Australia. From September through November moderate to severe deficits are forecast in the southeast, exceptional deficits will persist in Northern Territory’s Top End, and surpluses will continue to emerge along Queensland’s northeast coast.
Exceptional water deficits observed in recent months over much of Australia should diminish considerably in the near-term and through April 2018. However, significant deficits are forecast through October in: Western Australia from the Hamersley Range to the southernmost tip; southeastern Australia and Tasmania; the north across Northern Territory and Queensland; and, New Caledonia. Deficits may be exceptional north and south of Perth; east of Melbourne; central Tasmania; around the Gulf of Carpentaria; and Darwin. Along Queensland’s northeast coast surpluses will persist near Mackay. Past October moderate deficits will continue to emerge in Victoria and New South Wales.
Widespread exceptional water deficits from Northern Territory into Queensland are expected to dissipate. However, intense deficit conditions will persist through September in the southwestern extents of Western Australia, Darwin, Tasmania, coastal Victoria into New South Wales, and New Caledonia, and may persist into early 2018 from Perth south. Observed surpluses in the northwest and eastern Queensland will moderate but persist through December.
Widespread extreme water deficits spanning the middle of the country are expected to subside in the June through August forecast period. Deficits will persist in the Darwin region of the Northern Territory, on Tasmania, and in the southwestern extents of Western Australia through November. Recent surplus conditions in northern Western Australia, east of Darwin, and along the central Queensland coast are expected persist through November. In the December through February 2018 forecast period conditions are forecast to normalize with the exception of moderate deficits south of Darwin and in the Perth region of Western Australia.
