Widespread extreme to exceptional surpluses will dissipate in northern regions of Australia, as will exceptional deficits in several regions of the continent. Severe to extreme surpluses will persist in isolated regions of Western Australia and Northern Territory.
Exceptional deficits will remain widespread in several areas of the Canadian Shield and Atlantic regions. Exceptional surplus is anticipated in much of the Arctic Region.
Widespread deficits of varying intensity will occur in the southwest, northern, and northeastern states. Severe to extreme surpluses will remain in Florida, as well as in most noncontiguous states.
extreme to exceptional surpluses will persist in north-central and south-central regions of India. Exceptional surpluses are expected to emerge in eastern regions of the country, and in some areas of Nepal and Bangladesh. Extreme to exceptional deficits will expand in Afghanistan and Pakistan.
The forecast through February indicates that intense water deficits will nearly disappear, persisting in Tasmania, pockets of Victoria and New South Wales, and around Busselton in Western Australia. Deficits will be severe on the Murray River. Moderate deficits are forecast across northern Australia. In New Zealand, deficits are forecast in the north and surpluses in the south from Christchurch to Dunedin. Deficits in New Caledonia will moderate.
The forecast through December indicates that intense water deficits which have dominated much of Australia in prior months will retreat from most regions except the southeast. Deficits will be exceptional in Tasmania, and severe to exceptional along the southeast coast from Adelaide through Victoria and past Canberra. Moderate to severe deficits are forecast for New Zealand. Deficits in New Caledonia will moderate.
Regions likely to have significant water deficits for the 12-month period from February 2017 through January 2018 include: Florida (US), Brazil, northern Chile, French Guiana, Finland, Estonia, Latvia, northern Africa, Gabon, Saudi Arabia, Qatar, Papua New Guinea, and Tasmania (Australia). Water surpluses are forecast for: Idaho (US), La Pampa (Argentina), western European Russia, eastern Romania, southeastern Tanzania, the Volga River Basin, between the Ob and the Tom Rivers (Russia), and Kazakhstan. This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 9 May 2017.
Widespread exceptional water deficits in South Australia are forecast to nearly disappear from March through May leaving moderate deficits, but widespread deficits of varying severity are forecast in eastern Australia, particularly Queensland, with exceptional deficits in Central West, Queensland. Primarily moderate deficits are forecast for New South Wales, much of Victoria, and in Western Australia south of Perth. After May the forecast indicates considerable improvement with the near-absence of extreme to exceptional deficits, though severe deficits will emerge in eastern Tasmania.
From February through April moderate to exceptional deficits are forecast for much of Queensland. Primarily moderate deficits are forecast for New South Wales and southern Victoria. Moderate to severe deficits are expected to persist in North Island, New Zealand. Surpluses in the northern part of Western Australia and into the Victoria River Basin of Northern Territory are expected to diminish in severity. The forecast after April looks less eventful with moderate deficits tracing a path from Northern Territory’s Top End down along the eastern coast through New South Wales.
