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.

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.
