Australia & New Zealand: Water deficits forecast in southwestern Victoria, New Caledonia

Despite recent flooding in northern Tasmania, water deficits are forecast to persist in western Tasmania through April, with greatest severity in August. Deficits in New Caledonia are forecast to persist through October; deficits across some far northern regions of Australia may linger through November; and deficits in the southwest tip of Western Australia, south of Adelaide, and in the Melbourne area will persist through April. Water surpluses are forecast for the Fitzroy River Basin and southwest of there, also in the Upper Murray River catchment.

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.
