The forecast indicates that extreme to exceptional surpluses in northern Australia will diminish, though will still remain present in some regions of Northern Territory. Exceptional deficits across the continent will similarly dissipate, though severe deficits are expected along the southern coast of Victoria.
The forecast indicates that exceptional deficits will persist in northwestern China, southwestern Mongolia, and in the Yangtze River Basin. Surpluses of severe to exceptional intensity are expected to appear in western, southern, and northeastern regions of China.
The forecast indicates that extreme to exceptional surpluses will persist throughout India and Nepal. Exceptional deficits will expand throughout regions of Afghanistan and Pakistan.
The forecast indicates that exceptional deficits will occur in southwestern states, as well as in some areas of the Midwest. Severe to exceptional surpluses will linger in southern regions of Florida and in much of the noncontiguous U.S.
Regions forecast to have significant water deficits for the 12-month period from July 2019 through June 2020 include: Canada, Brazil, French Guiana, Chile, Finland, Estonia, Latvia, Ukraine, Egypt, Libya, United Arab Emirates, and Australia. Areas with a forecast of significant water surplus include: United States, Uruguay, Tanzania, Ireland, United Kingdom, India, Bangladesh, and China. This Watch List is based on ISciences Water Security Indicator Model v2 (WSIMv2) run on 7 October 2019
Widespread water deficits are forecast in much of the eastern half of the US through December and may be exceptional in the Virginias and Pennsylvania. Moderate to exceptional surpluses are predicted in central Minnesota. Surpluses will continue to emerge in northwestern Wisconsin, the western Upper Peninsula of Michigan, Florida, and Idaho and its neighbors. After December deficits in the East are expected to diminish, but intense deficits will persist in the Carolinas and southern Louisiana. Intense surpluses will continue to emerge in much of Minnesota.
Exceptional water surpluses are forecast in southeastern Texas through November along with surpluses of lesser severity along the Gulf. Exceptional deficits in the Northern Plains States will moderate. In the West, surpluses are forecast in Idaho, nearby areas of surrounding states, and pockets of central California. Deficits are expected in: northern Colorado, Kansas, Iowa, northeastern and southernmost Texas, southern Michigan, northwestern Pennsylvania, northern Maine, southern West Virginia, and the Southeast. After November moderate surpluses are forecast for the Ohio River Valley.
Regions forecast to have significant water deficits for the 12-month period from June 2017 through May 2018 include: Montana (US), Nayarit (Mexico), Amapá (Brazil), Italy, the Arabian Peninsula, Madhya Pradesh and Chhattisgarh (India), Cambodia, Mongolia, and Tasmania (Australia). Water surpluses are forecast for: US Gulf Coast, La Pampa (Argentina), Tanzania, Bangladesh, Tripura and Mizoram (India), western Myanmar, Laos, Jiangxi and Guangxi (China), and Transvolga (Russia). This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 8 September 2017.
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.
