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.

Intense water surpluses in the Ohio River Valley and the Lower Mississippi Basin will retreat considerably. Surpluses in western Montana and northern Idaho will remain intense. Exceptional deficits will persist in Utah and increase in southwest Colorado, but deficits in surrounding states will moderate. On the East Coast deficits will retreat, except in South Carolina and Georgia. Southern Florida will transition from deficit to surplus. Moderate deficits are forecast for Nebraska, eastern North Dakota, Minnesota, and northern Wisconsin.

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.
