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. 

Europe: Water deficits to persist in the Mediterranean

Europe: Water deficits to persist in the Mediterranean

Exceptional water deficits are expected to diminish considerably, but deficits of varying severity remain in the forecast for Finland, England, Belgium, France, Portugal, Spain, and across the Mediterranean through the Balkans. Exceptional surpluses will continue to emerge in western Russia and Poland, and surpluses are also forecast Romania, Moldova, Lithuania, Belarus, Germany, Czech Republic (Czechia), Austria, northern United Kingdom, Ireland, and southern Norway. From February through April surpluses will begin to moderate somewhat and the extent of deficits will shrink.

Canada: Extreme water surpluses to persist near Ottawa

Canada: Extreme water surpluses to persist near Ottawa

While the forecast for Canada will remain a patchwork of water anomalies, the most noticeable difference in the near-term is the widespread emergence of surplus conditions in Quebec and the slight downgrade of deficits west of Hudson Bay. Surpluses may be extreme near Ottawa. Significant deficits are forecast through January or longer in Jamésie, Quebec; the northern border between Quebec and Ontario; the southeast and southwest shores of Hudson Bay; and northwestern Ontario into central Manitoba. After January near-normal water conditions are forecast for large portions of eastern Canada.

Africa: Water deficits in South Africa to moderate; surpluses forecast in Tanzania

Africa: Water deficits in South Africa to moderate; surpluses forecast in Tanzania

Exceptional water deficits are forecast to diminish considerably November through January, but will continue to emerge in coastal Mauritania, western Niger, southeastern Nigeria, and southern Cameroon. Deficits in South Africa are expected to moderate but severe deficits are forecast along the Orange River and from Lesotho through Swaziland. Notable surpluses are expected in southern Sudan, South Sudan, Tanzania, Malawi, Mozambique, and Zambia. After January, moderate to severe deficits are forecast across North Africa, mild deficits in the south, and surpluses in Tanzania.

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.
