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.
United States: Water deficits ahead for South Atlantic States, surpluses Upper Midwest
The near-term forecast through January indicates several striking changes from the prior three months: a transition in the Gulf Coast from water surplus to deficit, a broad path of deficits in the South Atlantic States, and surpluses from the Upper Midwest through the Ohio River Valley into the Northeast. In the spring normal water conditions should return to the Ohio River Valley and the Northeast, surpluses will continue to emerge in the Upper Mississippi, and deficits will moderate in the Lower Mississippi, Texas, and the South Atlantic States.
United States: Water surplus ahead for E. Texas, Louisiana, S. Mississippi
Exceptional water surplus conditions spanning the Pacific northwestern states of Washington, Oregon and Idaho are expected to moderate in the near-term. Moderate surpluses are expected to develop along the central Gulf Coast and extend up the Mississippi Basin through the forecast period, settling over the northern Great Plains states by early 2018. Severe to exceptional deficits are forecast to develop over most of Alaska and moderate but persist throughout the forecast period.
United States: Exceptional water deficits forecast AR, MO; surpluses in ID
Though the extent of exceptional deficits from Missouri to the Gulf and to the Atlantic is expected to recede from March through May, exceptional deficits will persist in Arkansas, Missouri, and western Illinois, and moderate deficits will emerge throughout much of the US east of the Mississippi. Surpluses are forecast for the Pacific Northwest, Idaho, northern Nevada, Central California, western Nevada, and western Colorado and are expected to be exceptional in Idaho, parts of Central California, and along the Columbia River.
