Australia & New Zealand: Water deficits to downgrade but persist in Tasmania

Australia & New Zealand: Water deficits to downgrade but persist in Tasmania

Exceptional water deficits that have dominated southern Australia are expected to disappear, but deficits are forecast for northern Australia, the southwest, the southeast, and Tasmania. These deficits may be intense in Tasmania and in pockets of other aforementioned areas. Moderate deficits are expected along the Darling, Lachlan, and Macquarie Rivers in New South Wales. Surpluses will shrink but persist in the Mackenzie River region of Queensland and in southwest Kimberley region of Western Australia.

Australia & New Zealand: Deficits persist in Tasmania & Channel Country

Australia & New Zealand: Deficits persist in Tasmania & Channel Country

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.

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.
