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: 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.

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.

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.
