Australia & New Zealand: Water deficits to persist in Tasmania, surpluses near Bundaberg

Australia & New Zealand: Water deficits to persist in Tasmania, surpluses near Bundaberg

Exceptional deficits observed in recent months in Australia are forecast to nearly disappear, though intense deficits will persist in Tasmania through February and the southwestern tip of Western Australia through May. The near-term forecast includes deficits along Australia’s southeastern coast and in eastern New South Wales, and exceptional surpluses near Bundaberg, Queensland. After February surpluses near Bundaberg will recede and deficits will continue to emerge in the southwestern tip of WA, from the Fleurieu Peninsula in South Australia through Victoria, in Tasmania, and in New Zealand. 

Australia & New Zealand: Intense deficits to persist along the southeast coast & Tasmania

Australia & New Zealand: Intense deficits to persist along the southeast coast & Tasmania

Recent exceptional water deficits in Australia are forecast to diminish considerably overall, but persist in Tasmania and the southwestern tip of Western Australia. In the near-term, deficits are expected in much of South Australia, eastern New South Wales, and along Australia’s southeastern coast where deficits may be intense. Exceptional surpluses are forecast near Bundaberg, Queensland. After January, intense deficits will emerge in southwest Queensland and into New South Wales and South Australia. Primarily moderate deficits are forecast elsewhere in Queensland and in southeastern Australia.

Australia & New Zealand: Intense water deficits persist in Tasmania

Australia & New Zealand: Intense water deficits persist in Tasmania

Exceptional deficits observed in recent months over much of Australia are forecast to diminish considerably in the near-term and through June 2018. Through December, however, exceptional deficits are forecast for Tasmania and the southwest tip of Western Australia. Moderate to extreme deficits are forecast from Adelaide through Victoria and into the eastern Murray-Darling Basin in New South Wales. Moderate deficits are expected in New Caledonia and South Island, New Zealand. Surpluses are forecast for the Ord River Basin, northeastern Queensland, and Christchurch, New Zealand. 

Australia: Intense water deficits to persist in Busselton, WA & Tasmania

Australia: Intense water deficits to persist in Busselton, WA & Tasmania

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.

Australia & New Zealand: Water deficits to persist in WA, Tasmania, & New Caledonia

Australia & New Zealand: Water deficits to persist in WA, Tasmania, & New Caledonia

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.

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
