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.
Widespread exceptional water deficits from Northern Territory into Queensland are expected to dissipate. However, intense deficit conditions will persist through September in the southwestern extents of Western Australia, Darwin, Tasmania, coastal Victoria into New South Wales, and New Caledonia, and may persist into early 2018 from Perth south. Observed surpluses in the northwest and eastern Queensland will moderate but persist through December.
Widespread extreme water deficits spanning the middle of the country are expected to subside in the June through August forecast period. Deficits will persist in the Darwin region of the Northern Territory, on Tasmania, and in the southwestern extents of Western Australia through November. Recent surplus conditions in northern Western Australia, east of Darwin, and along the central Queensland coast are expected persist through November. In the December through February 2018 forecast period conditions are forecast to normalize with the exception of moderate deficits south of Darwin and in the Perth region of Western Australia.
The May through July forecast indicates that Australia will transition away from widespread and intense water deficits observed February through April. However, severe to exceptional deficits are forecast for southwestern Western Australia, the Darwin Region of Northern Territory, Tasmania, New South Wales, Victoria, much of the Cape York Peninsula in northern Queensland, and New Caledonia. Surpluses are expected to persist in northeastern Queensland, and a large block of surpluses in eastern Kimberly, Western Australia will transition to both deficits and surpluses. After July deficits will continue to retreat in Australia, except in Tasmania, leaving much of the country in near-normal conditions.
The April through June outlook indicates significant improvement as widespread and exceptional water anomalies are no longer evident in the forecast for South Australia, Queensland, and New South Wales. However, severe to exceptional deficits are expected to emerge throughout Tasmania and in Western Australia. Moderate deficits are forecast for central Australia, New Caledonia, and southern South Island, New Zealand. Surpluses will continue to emerge in eastern Queensland, and surpluses in the Kimberley Plateau in the northwest will diminish. After June primarily abnormal deficits will prevail over most of the country, with more severe deficits in eastern Tasmania, Western Australia, and in the north near Darwin.
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.
