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
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.
Australia & New Zealand: Water deficits persist in Tasmania
Mainland Australia is forecast to transition from widespread exceptional water deficit to mild conditions, with more intense deficits in Tasmania. Areas of moderate deficit include eastern South Australia, Victoria, the Murray-Darling Basin, and the east coast to Brisbane. Surpluses will persist in the Kimberley region, WA; shrink along the Victoria River and emerge in Arnhem Land, NT; re-emerge in northern Cape York Peninsula, QLD; and continue to emerge in the Mackenzie River area west of Rockhampton, QLD. Deficits in New Caledonia and New Zealand will moderate.
Australia & New Zealand: Intense water deficits persist in Tasmania & New Caledonia
Widespread, exceptional water deficits observed in recent months in Australia are forecast to nearly disappear, though intense deficits will persist in Tasmania and near Busselton, WA. Through April, primarily moderate deficits are forecast from the Eyre Peninsula in South Australia through much of Victoria and into New South Wales; for central Queensland to the Gulf of Carpentaria; and, northwest to Darwin, where deficits may be more severe. Deficits are expected to retreat significantly in New Zealand, but will continue to emerge in New Caledonia.
Australia & New Zealand: Water deficits diminish but persist in Tasmania and South Australia
Exceptional deficits observed in recent months are forecast to nearly disappear, though intense deficits will persist in western Tasmania and the southwestern tip of Western Australia. The near-term forecast includes moderate deficits in South Australia, becoming more intense past the Eyre Peninsula and along Victoria’s coast. Moderate deficits are expected in the eastern Murray-Darling Basin which may be more severe in Riverina, and moderate deficits are forecast for New Zealand. After March, deficits will be mild overall but more severe in Busselton, Tasmania, and New Zealand.
