United States

United States: Water deficits persist in the Northeast, surpluses in Upper Midwest

United States: Water deficits persist in the Northeast, surpluses in Upper Midwest

The outlook for the United States through December indicates that water deficits will continue to dominate much of the northeastern US, though the expanse of exceptional deficits is expected to shrink. Significant deficits will also persist from Ohio through the South, in Southern California, and along the Missouri and Yellowstone Rivers. A large block of surpluses will persist in Wisconsin, Minnesota and Iowa. After December deficits across the country will diminish considerably but surpluses in the upper Midwest are expected to persist and moderate surpluses will emerge in the Rocky Mountain States.

United States: Water deficits to lessen, surpluses in Upper Mississippi Basin

United States: Water deficits to lessen, surpluses in Upper Mississippi Basin

The forecast for the United States through November includes widespread extreme water deficits throughout the East and on the Missouri and Yellowstone Rivers, with moderate deficits in the West. A large pocket of surpluses is forecast along the Upper Mississippi River, encompassing southern Minnesota, much of Wisconsin, eastern Iowa, and northern Illinois. From December through February deficits across the US are forecast to diminish; surpluses will persist in Minnesota and Wisconsin and will continue to emerge southward.

United States: Extreme water deficits forecast in the Northeast, Southeast

United States: Extreme water deficits forecast in the Northeast, Southeast

The outlook for the United States through October indicates the persistence of widespread severe to extreme water deficits throughout the Northeast and the continued emergence of severe deficits in the Southeast. Deficits are also forecast for the West, Southwest, and Northern Border States. Water surpluses are forecast in western Wisconsin, southeastern Minnesota, eastern Iowa, Nebraska, eastern Texas, and southwestern Kentucky. After October, widespread deficits are forecast to diminish in extent and severity with the exception of the Missouri and Yellowstone Rivers, and in the Southeast. Surpluses are expected to persist in Wisconsin, eastern Minnesota, northeastern Iowa, and Nebraska. Moderate surpluses will emerge in Southern California and central Arizona, and later, throughout the Rocky Mountains States. 

United States: Exceptional water deficits forecast in the Northeast, surpluses in eastern Texas

United States: Exceptional water deficits forecast in the Northeast, surpluses in eastern Texas

The outlook for the United States indicates widespread exceptional water deficits throughout the Northeast from July through September. Deficits of varying severity are also forecast for parts of the Midwest and Upper Midwest, the Pacific Northwest, and California. Widespread water surpluses are expected in eastern Texas and surpluses are also forecast in West Virginia and Nebraska. After September deficits will diminish with the exception of the Missouri and Yellowstone Rivers. Surpluses in Texas will diminish. Widespread surpluses are forecast to emerge in Wisconsin and across the Mississippi River into Minnesota.

United States: Water deficits to persist in the Northeast, surpluses in Texas

United States: Water deficits to persist in the Northeast, surpluses in Texas

The outlook for the United States indicates widespread and varied water anomalies for much of the country. Water deficits are forecast for much of the Northeast, parts of the Southeast, Upper Midwest, and West, which are expected to be most severe June through August, particularly in the Northeast and West. Water surpluses are forecast for a vast portion of Texas which are also expected to be of greatest extent and exceptional severity through August.

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.
