The forecast through June indicates that water surplus will shrink in European Russia, persist in the Tom River watershed, and transition to deficit in the Ob River watershed. Deficits will emerge surrounding Orenburg on the Ural River, and between the Lower Tunguska and the Angara Rivers in the Yenisei watershed. In Kazakhstan, surpluses will emerge and persist in the north, but diminish elsewhere; deficits will emerge in the west, which will be extreme on the Ural River. Intense deficits are forecast for Turkmenistan, eastern Uzbekistan, western Kyrgyzstan, and Tajikistan.

Water surpluses of varying intensity are forecast in Russia from western European Russia through the Western Siberian Plain through February 2018 or longer, and are expected to be exceptional in the TransVolga region and in the Upper Ob River Basin surrounding Novosibirsk. Exceptional surpluses in Kazakhstan will transition to conditions of both deficit and surplus through February. Surpluses are forecast for Kyrgyzstan, especially Bishkek. Deficits in Turkmenistan and Uzbekistan are forecast to moderate somewhat in the near-term but persist, diminishing after November.
Regions forecast to have significant water deficits for the 12-month period from June 2017 through May 2018 include: Montana (US), Nayarit (Mexico), Amapá (Brazil), Italy, the Arabian Peninsula, Madhya Pradesh and Chhattisgarh (India), Cambodia, Mongolia, and Tasmania (Australia). Water surpluses are forecast for: US Gulf Coast, La Pampa (Argentina), Tanzania, Bangladesh, Tripura and Mizoram (India), western Myanmar, Laos, Jiangxi and Guangxi (China), and Transvolga (Russia). This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 8 September 2017.
Water surpluses of varying intensity are forecast in Russia stretching from western European Russia to the Western Siberian Plain through April 2018 and are expected to be exceptional in large pockets of the Volga Basin and between the Upper Ob and Tom Rivers surrounding Novosibirsk from August 2017 through January 2018. In the near-term, August through October, deficit conditions in Turkmenistan and Uzbekistan are expected to ameliorate, leaving modest deficits. Exceptional surpluses will continue to emerge in northern Kyrgyzstan, including Bishkek.
Regions forecast to have significant water deficits for the 12-month period from May 2017 through April 2018 include: Brazil, Belgium, Spain, Italy, Finland, northern Africa, Gabon, Somalia, Saudi Arabia, Turkmenistan, Cambodia, Mongolia, and Tasmania. Water surpluses are forecast for: La Pampa (Argentina), Tanzania, western Russia, Bangladesh, Manipur and Mizoram (India), and eastern Thailand.

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.
Widespread pockets of exceptional water surplus conditions will continue across central Russia and northern and southern Kazakhstan for much of the forecast period, moderating towards early 2018. Increased flows are expected in the Ob and Volga River basins. Recent exceptional deficits across northern Russia may retreat somewhat to the northern regions of Krasnoyarsk Krai. Moderate deficits are forecast to develop over much of Turkmenistan and Uzbekistan from June through November before moderating in early 2018.
Drier than normal conditions will persist in many parts of northern Russia from the White Sea past the Central Siberian Plateau through August 2017, though the extent of exceptional deficits will diminish somewhat. Both surpluses and deficits are forecast for the Ural River watershed in northwestern Kazakhstan, and surpluses are forecast for central and eastern Kazakhstan. Overall, moderate deficits are forecast for Turkmenistan and Uzbekistan, and surpluses in Kyrgyzstan.
Drier than normal conditions will continue to dominate much of northern Russia from the White Sea to the Central Siberian Plateau through July, though the extent of exceptional deficits will diminish considerably. The Ural River Basin in northwestern Kazakhstan will continue to experience exceptional surplus and surpluses are also forecast for central Kazakhstan. Overall, moderate deficits are forecast for Turkmenistan and Uzbekistan, and surpluses in eastern Kyrgyzstan.
