The forecast through October indicates that exceptional water deficits will diminish considerably but widespread deficits will continue to affect many parts of Central, Eastern, and Northern Europe and will be especially intense in Finland, Estonia, and southern Germany. Moderate deficits will increase in France. Surpluses are forecast for Hungary, Serbia, Kosovo, Romania, Bulgaria, and Moldova. On the Iberian Peninsula, surpluses will diminish overall, but persist in many parts of Spain and may be exceptional in the south.
The forecast through October indicates that water deficits will moderate overall in Central Asia, though conditions may be more severe along the Amu Darya River in eastern Turkmenistan, the Zaravshan River in eastern Uzbekistan, and the Ural River through northwestern Kazakhstan into Russia. Moderate deficits will emerge in central Kazakhstan. In Russia, deficits will downgrade in the Caucasus. Surpluses are forecast along the Ob, Irtysh, and Ishim Rivers and in the Tom River watershed, and wide band of surplus will extend to the Gulf of Ob.
Through the next several months, widespread water surpluses in the center of China will shrink and downgrade, and surpluses further east in Hubei, Henan, and Anhui will transition to mild deficit. In the south, moderate to severe surpluses will increase in Yunnan and western Guangxi. Deficits will shrink in Mongolia, Inner Mongolia, and Southeast China. Moderate to extreme deficits will persist in Liaoning and Jilin in the northeast, and will emerge on the Korean Peninsula and Honshu, Japan.
Regions forecast to have significant water deficits for the 12-month period from May 2018 through April 2019 include: the US Pacific Northwest, southern Mexico, Brazil, Chile, Central and Northern Europe, northern Africa, and Afghanistan. Areas with a forecast of significant water surplus include: Tanzania, Kenya, Bangladesh, Myanmar, Laos, and Sichuan, China. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 9 August 2018.
The August Outlook indicates much warmer than normal temperatures in much of Europe reaching exceptional intensity in parts of Central Europe and southern Scandinavia. Precipitation is expected to be above average in Greece, Italy, and across the Mediterranean into Algeria.
Exceptional water deficits are forecast to decrease, though vast blocks will persist. These areas include: Quebec from the Caniapiscau Reservoir to the St. Lawrence River; surrounding Lake Mistassini, QC; Ontario’s eastern border; northeastern Manitoba; the Lower Athabasca River region in Alberta; surrounding Prince George, British Columbia; and, northwestern BC. Intense surpluses will persist from northwestern Saskatchewan reaching west to Fort McMurray, Alberta, and in southeastern BC.
Moderate water deficits, punctuated by more intense pockets, are expected across a large portion of eastern and southeastern Australia, scattered across the north, and in the southwest. Deficits may be intense in the southwest, and in the east near Adelaide and Melbourne, from Canberra to Sydney, and around Brisbane. Moderate deficits are forecast in New Zealand and intense deficits in New Caledonia.
In Central Asia, water deficits will increase and intensify in Turkmenistan, Uzbekistan, western Kazakhstan, and Tajikistan and extreme deficits will persist in central Kyrgyzstan. Surpluses are forecast for northern Kazakhstan and south of Lake Balkhash. In Russia, deficits will moderate in the Caucasus and North Caucasus. Severe deficits will increase along the Ural River around Orenburg. Surpluses are forecast along the Ob, Irtysh, and Ishim Rivers and the Upper Ob and Tom River Basins. Moderate surpluses are forecast for the Northern European Plain.
Through September, exceptional water deficits in Mongolia, Inner Mongolia, and southern Xinjiang will diminish considerably, as well as in Southeast China and Taiwan. Moderate to severe deficits will persist in the Southeast with some pockets of exceptional deficit lingering in Hunan. Widespread surpluses will diminish overall, but surpluses of varying severity will persist in the Lower and Middle Reaches of the Yellow River, the Han River Basin, Qinghai, Yunnan, Hainan, and western Tibet.
The forecast through September indicates that widespread water deficits in Central, Eastern, and Northern Europe will downgrade from exceptional levels in most affected regions but remain intense, especially in Central Europe and Finland. Deficits are expected to be extreme on many rivers including the Oder, Elbe, Danube, and Rhine. Surpluses are forecast for the Iberian Peninsula, parts of Eastern Europe and the Balkans, and European Russia.
