Southeast Asia and the Pacific: Deficits ...

Exceptional surpluses throughout Maritime Southeast Asia will mostly diminish, though pockets of severe to exceptional deficits will persist in portions of the Philippines, Indonesia, Papua, West Papua, and New Guinea.

South Asia: Deficits remain in Afghanistan, ...

Exceptional surpluses in India will mostly dissipate, transitioning to moderate to severe surpluses. Exceptional deficits will remain in Afghanistan and Pakistan. 

South Asia: Deficits remain in Afghanistan, Pakistan, surpluses persist in India

East Asia: Widespread, exceptional water surpluses continue to emerge on Yangtze

East Asia: Widespread, exceptional water surpluses continue to emerge on Yangtze

Water surpluses in the Lower Yangtze are expected to become widespread and exceptional. Exceptional surpluses are also forecast for the Middle and Upper Yellow River, Qinghai, and western Tibet. Intense deficits will continue to emerge in Mongolia and Inner Mongolia, deficits in South Korea will increase, and deficits in southeastern China will moderate, except in Fujian. After January exceptional deficits will continue to emerge to form a vast stretch across much of Mongolia and Inner Mongolia. Deficits will emerge around the Bohai Sea, and surpluses in the Lower Yangtze will diminish.

United States: Water deficits ahead for South Atlantic States, surpluses Upper Midwest

United States: Water deficits ahead for South Atlantic States, surpluses Upper Midwest

The near-term forecast through January indicates several striking changes from the prior three months: a transition in the Gulf Coast from water surplus to deficit, a broad path of deficits in the South Atlantic States, and surpluses from the Upper Midwest through the Ohio River Valley into the Northeast. In the spring normal water conditions should return to the Ohio River Valley and the Northeast, surpluses will continue to emerge in the Upper Mississippi, and deficits will moderate in the Lower Mississippi, Texas, and the South Atlantic States.

Middle East: Water deficits persist in Sana'a & Aden, Yemen

Middle East: Water deficits persist in Sana'a & Aden, Yemen

Exceptional water deficits are forecast to nearly disappear in the near-term leaving primarily moderate to severe deficits across the region. Severe deficits are forecast November through January along stretches of the Euphrates River, and deficits of greater intensity are expected along Turkey’s northern coast and in southwestern and southeastern Yemen. Overall, water deficits will diminish slightly in extent and intensity from February through April.

Mexico, Central America & the Caribbean: Water surplus to persist in Nicaragua

Mexico, Central America & the Caribbean: Water surplus to persist in Nicaragua

Though intense water surpluses will persist in Central America, the extent of exceptional surpluses will diminish. Deficits will continue to emerge in pockets across northern Mexico, diminishing in Sonora but emerging with greater severity in Chihuahua. Surpluses in northern Coahuila and Nuevo Leon will begin to transition to both deficit and surplus. Moderate deficits will emerge in southern Mexico and Guatemala. After January, exceptional deficits are expected to emerge in Jalisco, Mexico, and deficits across the northern states will diminish.

Central Asia & Russia: Water deficit forecast for Turkmenistan; surplus for Volga Basin

Central Asia & Russia: Water deficit forecast for Turkmenistan; surplus for Volga Basin

In the near-term water, surpluses reaching exceptional intensity will continue to emerge in Russia’s Volga River Basin and on the Ob, Vakh, and Tom Rivers, and in Aktobe, northern Kostanay, and western Akmola Regions, Kazakhstan. Exceptional deficits will increase in Yamal, Russia. Moderate to severe deficits are expected in Turkmenistan and Uzbekistan. In the spring, Volga Basin surpluses should downgrade, though remain widespread. Surpluses will persist between the Tom and Yenisei Rivers, and along the Ob and Irtysh Rivers. Severe deficits will continue to emerge in Turkmenistan and Uzbekistan. 

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.
