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.
Central Asia: Water surpluses remain in the forecast for western Russia
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.
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.
Central Asia & Russia: Water surpluses forecast for Kazakhstan, Kyrgyzstan
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.
Central Asia & Russia: Water surpluses forecast for Volga River Basin, & from Ob to Tom River
Widespread exceptional water deficits in northern Russia observed in the prior three months are forecast to retreat May through July. However, drier than normal conditions will persist from the Yamal Peninsula to the Sea of Okhotsk. Exceptional surpluses are forecast in the Volga River Basin, the Irtysh, and between the Ob and the Tom Rivers. Surpluses will continue to emerge in many parts of Kazakhstan and are also forecast for eastern Uzbekistan, Kyrgyzstan, and Tajikistan. Moderate deficits are forecast for Turkmenistan and central Uzbekistan. Beyond July the forecast shows a similar geographic distribution of anomalies but with some changes in conditions.
