The forecast through August 2019 indicates persistent water surpluses in a wide path through the center of the country in the Mississippi River Basin and well into the Missouri, Arkansas, and Red River Basins, including exceptional anomalies in South Dakota. Surpluses of varying intensity are expected in the Rockies, central Arizona, California, Oregon, and in the Northeast. Deficits are forecast for pockets of Washington, North Dakota, Wisconsin, and southeastern states.

The forecast through June indicates that surpluses East of the Mississippi will nearly disappear. Moderate deficits are forecast for the South Atlantic States and parts of the Deep South. Surpluses are forecast in the center of the country radiating from Nebraska and Iowa and will emerge in the Rockies with intense anomalies in many places, particularly Colorado. Primarily moderate surpluses are forecast for nearly all of California as well as northern Arizona and much of Oregon.
Regions forecast to have significant water deficits for the 12-month period from January 2019 through December 2019 include: French Guiana, Brazil, Finland, Latvia, Egypt, Somalia, Angola, and United Arab Emirates. Areas with a forecast of significant water surplus include: northern Iraq, western Iran, Afghanistan, Tanzania, and southeastern China. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 10 April 2019.
Most notable in the forecast through May is the absence of widespread, intense water surpluses observed in the East in prior months and the emergence of surpluses in the West. Surpluses will shrink and downgrade in the center of the country but remain widespread in a broad path from southern Minnesota to the Gulf of Mexico and will be intense in Kansas. Moderate surpluses will cover much of California, and many Rocky Mountain States will transition from deficit to surplus.
Most notable in the forecast through April is the absence of widespread, intense water surpluses observed in the East in prior months. Surpluses will, however, persist in a massive path down the center of the country from Wisconsin through Texas, and moderate surpluses will emerge in the Rocky Mountains, in California from San Francisco Bay to the southern border, and along the Missouri and Colorado Rivers. Surpluses will be exceptional in central Kansas, on the Arkansas River, and in central Texas.
Regions forecast to have significant water deficits for the 12-month period from November 2018 through October 2019 include: Quebec (Canada), Finland, Latvia, Somalia, Angola, Iran, Thailand, Cambodia, and Australia. Areas with a forecast of significant water surplus include: Kansas and Texas (US), Paraguay, Uruguay, Syria, Tanzania, and China. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 8 February 2019.
The forecast through November indicates that water deficits will downgrade considerably overall leaving mild to moderate deficits, but deficits will be intense along the Arkansas River through Kansas and Colorado, western Colorado, northeastern Utah, along the Canadian River through Oklahoma and the Texas Panhandle, and in the US Northeast. Areas of surplus include: Montana, the Black Hills of South Dakota, northern Nebraska, Iowa, Wisconsin, and eastern Pennsylvania.
For the next several months, water deficits will diminish overall but intense deficits are forecast for southern California, the Willamette Valley in Oregon, along the Arkansas River, and western Colorado. Areas of moderate deficit include northern Minnesota and from Missouri to the Gulf. Surpluses are forecast for northern Nebraska, the Black Hills of South Dakota, southern Montana, the Pecos River in New Mexico into Texas, eastern Pennsylvania, Maryland, northern Virginia, coastal North Carolina, and much of Florida from Jacksonville past Lake Kissimmee.
Regions forecast to have significant water deficits for the 12-month period from May 2018 through April 2019 include: the US Pacific Northwest, southern Mexico, Brazil, Chile, Central and Northern Europe, northern Africa, and Afghanistan. Areas with a forecast of significant water surplus include: Tanzania, Kenya, Bangladesh, Myanmar, Laos, and Sichuan, China. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 9 August 2018.
The forecast through September indicates that, while exceptional water deficits will diminish overall and in the Southwest and Southern Rockies in particular, moderate to severe deficits are expected in a wide path from Missouri to the Gulf. Deficits may be intense in Louisiana, along the Arkansas and Canadian Rivers, and the Pacific Northwest coast. In the Northeast, deficits will persist and spread further in Maine. Significant surpluses will persist in the Northern Rockies, and surpluses will emerge in much of Florida.
