Central Asia & Russia: Water surpluses forecast from the Irtysh to the Tom River, Russia

Central Asia & Russia: Water surpluses forecast from the Irtysh to the Tom River, Russia

Widespread and exceptional water deficits observed in Russia in the prior three months are forecast to retreat April through June. However, drier than normal conditions will persist from the White Sea to the Lena River. Surpluses are forecast from the Irtysh to the Tom River, along the Middle Ob River, and between the Volga River and the Belaya River. Surpluses will continue to emerge in the many areas of Kazakhstan as well as in Kyrgyzstan, eastern Uzbekistan, and western Tajikistan. Moderate deficits are forecast for western Uzbekistan and parts of Turkmenistan.

South Asia: Severe to exceptional water deficits forecast for central & southern India

South Asia: Severe to exceptional water deficits forecast for central & southern India

Severe to exceptional water deficits are forecast to emerge April through June across central and southern India. Deficits will also emerge near Karachi, Pakistan and will continue to emerge in western Pakistan. Surpluses are forecast in Jammu and Kashmir, eastern Afghanistan, and along the northern Indus River in Pakistan. From July through September deficits in India will decrease in intensity but increase in extent as deficits emerge in the Chambal River watershed. Severe to extreme deficits will persist in Madhya Pradesh. Moderate to severe deficits are also forecast to emerge throughout Bangladesh. 

Southeast Asia & the Pacific: Deficits to emerge on Java; surpluses Vietnam, Malay Peninsula

Southeast Asia & the Pacific: Deficits to emerge on Java; surpluses Vietnam, Malay Peninsula

From April through June water deficits are forecast to emerge on Java, southern Sumatra, and southern Borneo, but will recede in Cambodia except for a pocket of exceptional deficits northeast of Tonlé Sap. Surpluses are forecast for central Vietnam, the Malay Peninsula, northern Sumatra, northeast Borneo, and Mindanao. After June, deficits are forecast for most of the region, with severe to exceptional deficits in Malaysia, Indonesia, Papua New Guinea, and eastern Mindanao.

East Asia: Water deficits to emerge in South Korea, Japan, & persist in Mongolia

East Asia: Water deficits to emerge in South Korea, Japan, & persist in Mongolia

A return to normal water conditions is forecast for Southeast China from April through June – a change from surpluses observed in prior months. Deficits are forecast to emerge in South Korea, Japan, Northeast China, the Shandong Peninsula, Henan, and Shaanxi. Severe to exceptional deficits will persist in southern Mongolia, western Inner Mongolia, the Tarim Basin and eastern Dzungaria regions of southern Xinjiang, and southern Liaoning. Surpluses are forecast for northern Sichuan and much of Qinghai. The forecast for July through September indicates the persistence of deficits in western Inner Mongolia and Mongolia, and the emergence of deficits in the Sichuan Basin. 

Australia & New Zealand: Exceptional water deficits to emerge in Tasmania

Australia & New Zealand: Exceptional water deficits to emerge in Tasmania

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.

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.
