Central Asia & Russia: Water surpluses in the Volga River Basin and eastern Novosibirsk Oblast

Central Asia & Russia: Water surpluses in the Volga River Basin and eastern Novosibirsk Oblast

In Russia large pockets of exceptional surplus conditions are forecast for the Volga River Basin and from the Lower Ob River to the Tom River, persisting through March 2018. Deficits will continue to emerge in much of eastern Russia through March, though they are not expected to reach exceptional severity beyond September. Moderate to severe surpluses will emerge from the Ural Mountains to the western edge of the Central Siberian Plateau from October through March. Surpluses will persist in many parts of Kazakhstan and throughout Kyrgyzstan. Moderate to severe deficits are forecast for Turkmenistan and Uzbekistan through December, diminishing thereafter. 

Europe: Water deficits to persist in Europe through September

Europe: Water deficits to persist in Europe through September

Water deficits will continue to dominate much of Europe through September but will diminish significantly thereafter. Through September, however, exceptional deficits will persist in Finland, Estonia, and many pockets of Western and Central Europe. Severe to exceptional deficits are expected along many rivers including the Danube, the Drava, the Rhine, the Rhône, and the Loire. Surpluses in Western Russia will persist through September but diminish in extent and severity except in Murmansk, where exceptional surpluses will continue to emerge. Exceptional surpluses are forecast for eastern Romania and Moldova which will persist through December. 

Mexico, Central America, & the Caribbean: Water deficits in Nayarit, Puerto Vallarta, Puebla

Mexico, Central America, & the Caribbean: Water deficits in Nayarit, Puerto Vallarta, Puebla

Recent severe water deficits across Mexico and western Cuba are expected to diminish in the next few months, shifting toward the south and bringing moderate deficit conditions to Guatemala, El Salvador, Honduras, and western Nicaragua by October. Surplus conditions in southern Nicaragua and northern Costa Rica are forecast to subside after September. 

Australia & New Zealand: Water deficits to persist in southwest WA and Tasmania

Australia & New Zealand: Water deficits to persist in southwest WA and Tasmania

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.

East Asia: Water deficits forecast for NE China, eastern Sichuan, southern Yunnan

East Asia: Water deficits forecast for NE China, eastern Sichuan, southern Yunnan

Recent widespread exceptional deficits in Mongolia into northeastern China, around the Bohai Sea, and on the Korean Peninsula are forecast to moderate. Severe to exceptional deficits will persist in western Inner Mongolia through early 2018, joined by a broad band of intense deficits that will develop across southern Mongolia westward through central Xinjiang from September on. Moderate to severe deficits will emerge July through September in northeast China, trailing southwest into eastern Sichuan, and in southern Yunnan. Severe to exceptional surpluses are forecast for the southern Yangtze River Basin through September, moderating thereafter.

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.
