Europe: Transition forecast from water deficits to surpluses in Central Europe

Widespread water deficits may persist in much of Continental Europe while surpluses may continue in Ireland, Scotland, and northern Sweden. Though deficits are expected to persist in much of Europe for the next few months, they may diminish and transition to moderate surpluses in Central Europe, particularly Germany, January through June 2016.

Mexico: Water deficits to persist in southern Mexico, parts of Central America

Water deficits may continue to emerge throughout much of Mexico with particular severity and extent in southern Mexico. Deficits are forecast to persist in parts of Central America. Surpluses may persist in northwest Mexico along the conjoined borders of Sonora and Chihuahua, down through Sinaloa. 

Southeast Asia & the Pacific: Moderate to exceptional water deficits may persist in many areas

Many parts of Southeast Asia and the Pacific may continue to experience moderate to exceptional water deficits in the coming months, particularly southern Sumatra, Java, Borneo and neighboring Sulawesi, and New Guinea.

South America: Exceptional water deficits to persist across northern Brazil, surpluses in southern Brazil, Uruguay, Argentina

Exceptional water deficits may persist across northern Brazil, coastal Peru, western Bolivia, and northern Chile. Surpluses may emerge in Ecuador and northern Peru. Surpluses are also forecast for central Paraguay, southern Brazil, Uruguay, and Argentina and are expected to increase in extent and severity with widespread exceptional surpluses.

United States: Water deficits persist in the Northwest, moderate surpluses forecast for California

Water deficits are forecast in the US Northwest and eastward through the Great Lakes region for the 12-month period ending June 2016. California may transition to moderate surpluses. Surpluses are also forecast in the Central and Southern Plains and in Virginia. Moderate to exceptional deficits are expected in southern Arkansas, Louisiana, and Mississippi, with both deficits and surpluses emerging in central Louisiana.

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.
