United States: Intense water deficits to persist in OR, MO, AR, LA; surpluses in FL

United States: Intense water deficits to persist in OR, MO, AR, LA; surpluses in FL

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.

United States: Water deficits to diminish in the SW, surpluses ahead for FL

United States: Water deficits to diminish in the SW, surpluses ahead for FL

The forecast through August indicates deficits in the Northeast, which could be exceptional in southern Maine. Moderate to severe surpluses are forecast scattered from Virginia through Alabama, and covering nearly all of Florida. Primarily moderate deficits are forecast for the Mississippi River Basin. Intense deficits are forecast for western Colorado, northern Utah, western Oregon, western Washington, and southernmost Texas. Primarily moderate deficits are expected in California. Surpluses will diminish in Idaho and downgrade slightly from exceptional in Montana.

United States: Intense water surpluses to persist in Idaho and Montana

United States: Intense water surpluses to persist in Idaho and Montana

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.

United States: Severe water deficits forecast to persist in the Southwest, surpluses in Idaho

United States: Severe water deficits forecast to persist in the Southwest, surpluses in Idaho

The forecast through June indicates that deficits will diminish and downgrade in the South Atlantic States, retreat considerably in the Gulf States, downgrade to moderate in the Southern Plains States, persist with intensity in the Southwest, and shrink in central California. Surpluses are forecast for Idaho, Montana, western Wyoming, Nebraska, South Dakota, Iowa, Missouri, and along the Missouri and Yellowstone Rivers. Surpluses will be exceptional in Idaho and Montana. Surpluses in the Ohio River Valley will diminish. After June, anomalies will downgrade, but persist.

United States: Water surplus to persist in Ohio River Valley, emerge on Missouri River

United States: Water surplus to persist in Ohio River Valley, emerge on Missouri River

Water surpluses will continue to emerge in southern Michigan and the Ohio River Valley. Exceptional surplus is expected on the Missouri River, western Montana, Idaho, and Washington. Intense deficits will continue in the West and Southwest. Moderate deficits are forecast for Oregon, Kansas, western Oklahoma, and most of Texas west of the Brazos River, with severe conditions in the Panhandle. Missouri, Arkansas, Louisiana, and Mississippi will transition out of deficit, with moderate surplus emerging in Arkansas into surrounding states. Deficits in the Mid-Atlantic States will shrink.

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.
