Intense deficits are also forecast along the Arkansas River, and in Colorado, and north-central Utah. Other areas of deficits include the Canadian River, the Rio Grande through New Mexico, and Maine.
United States: Water surpluses forecast to increase in central Gulf Coast
The near-term forecast through September shows a distribution pattern of water anomalies similar to the prior three months with some decrease in intensity. However, surpluses are forecast to increase in the central Gulf Coast. Beyond September water anomalies will continue to become less severe, though pockets of exceptional surplus will persist in Idaho and its neighbors. The forecast through March 2018 indicates the emergence of primarily moderate surpluses in many parts of the country.
