ISciences Worldwide Water Watch List April 2024

The forecast for April 2024 expects significant water deficits for the 12-month period of January 2024 through December 2024 in South America, northeastern Africa, and the Middle East. Areas expected to experience surplus include eastern to eastern Africa, northern Australia, Europe, and Southeast Asia.

The forecast indicates that exceptional deficits will persist in northwestern regions of China, but lessen in size in northern and northeastern China. Surpluses occurring in Tibet are also expected to remain but diminish in size.

Southeast Asia and the Pacific: Surplus spreads ...

The forecast indicates that deficits will persist throughout Mainland Southeast Asia, but decrease in intensity, becoming mostly moderate to severe anomalies. Intense surplus is expected to expand throughout Maritime Southeast Asia, particularly in central Indonesia, Papua, and Papua New Guinea.

South Asia: Surplus expands throughout India

The forecast indicates that most exceptional deficits in Pakistan and Afghanistan will dissipate, though some regions are expected to experience lingering deficits. India is expected to observe widespread surplus throughout the country. 

South Asia: Surplus expands throughout India

Southern Plains

United States: Water surplus to persist in Ohio River Valley, emerge on Missouri River

United States: Water surplus to persist in Ohio River Valley, emerge on Missouri River

Water surpluses will continue to emerge in southern Michigan and the Ohio River Valley. Exceptional surplus is expected on the Missouri River, western Montana, Idaho, and Washington. Intense deficits will continue in the West and Southwest. Moderate deficits are forecast for Oregon, Kansas, western Oklahoma, and most of Texas west of the Brazos River, with severe conditions in the Panhandle. Missouri, Arkansas, Louisiana, and Mississippi will transition out of deficit, with moderate surplus emerging in Arkansas into surrounding states. Deficits in the Mid-Atlantic States will shrink.

United States: Water deficits to emerge this Spring in Ohio, lower Mississippi Valleys, then upper Mississippi & Northwest

Overall, widespread moderate to exceptional water deficits are forecast for Montana, Wyoming, North Dakota, Minnesota, Michigan, and much of the Mississippi and Ohio Valleys. Surpluses are forecast for the Southern Plains and southern Florida. In April and May deficits are forecast for much of the country east of the Mississippi, and will emerge thereafter across the North, in the Central Plains, Northern Great Plains, and in the West, tracing paths along many major rivers. Though decreasing in severity, widespread deficits will persist through November. 

ISciences Worldwide Water Watch List March 2016

Regions likely to encounter significant water deficits in the coming months include: the Mississippi and Ohio River Valleys, US; southern Mexico; northern Brazil; Mediterranean Europe; Finland and Estonia; coastal West Africa; western Turkey; Yemen; and Southeast Asia. Significant water surpluses are forecast for: the Southern Plains and southern Florida, US; northwestern Mexico; central Argentina; Ireland; Kenya; central Kazakhstan; Java; and southeast China. This watch list is based on ISciences' Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 9 March 2016.

United States: Water deficits to emerge this Spring in Ohio and lower Mississippi Valleys first, then Montana, North Dakota, Minnesota, Wisconsin, and throughout the Northeast.

Widespread moderate to extreme deficits are forecast for Montana, Wyoming, North Dakota, Minnesota, Michigan, much of the Mississippi Valley, and New England. Surpluses are forecast for the Southern Plains, east Texas, and southern Florida. Both deficits and surpluses are expected in in the Pacific Northwest, and parts of the Southeast. 

United States: Winter water surpluses in Midwest transition to deficits across north and in the Mississippi Valley beginning in Spring

Widespread moderate to extreme deficits are forecast for Montana, Wyoming, Michigan, much of the Mississippi Valley, and New England. Surpluses are forecast for the Southern Plains, east Texas, coastal North and South Carolina, and eastern Florida. Both deficits and surpluses are expected in the Pacific Northwest, the Southeast, Missouri and Arkansas.

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.
