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. 

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.
