United States: Widespread water surpluses WI to TX & NY to GA

Through February, widespread intense water surpluses will persist in the center of the country and in the east. Surpluses will cut a broad path from Michigan’s Upper Peninsula, passing through Iowa and reaching the eastern half of Texas. Surpluses are also forecast for the northern Ohio River Basin and in the east from southern New York through Florida’s Panhandle, and will be extreme in eastern Pennsylvania. Areas of deficit include: northern New York, northern Maine, southern Florida, northwestern Wyoming, Colorado, and western Oregon.

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.

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.
