Regions likely to have significant water deficits for the 12-month period from November 2016 through October 2017 include: Arkansas, Quebec, French Guiana, Chile, Brazil, France, Germany, Finland, Estonia, Latvia, northern Africa, Kenya, Tanzania, Yemen, Saudi Arabia, United Arab Emirates, Arctic Russia, southern India, Cambodia, Papua New Guinea, Inner Mongolia, and Queensland. Water surpluses are forecast for: Idaho, Nevada, California, northern Botswana, northeastern Afghanistan, central Vietnam, southern Thailand, and Shanghai. This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 8 February 2017.
The February 2017 Outlook indicates much warmer than normal temperatures for France, Germany, United Kingdom, Scandinavia, Myanmar, and north-central Mexico, along with warm anomalies of varying severity in many other places. The Central Amazon Basin should see much wetter than normal conditions.
The forecast through March indicates widespread and exceptional water deficits in South Australia, Victoria, and New South Wales. Deficits of varying severity are forecast for Queensland’s Sunshine Coast, Northern Territory’s Top End, central Tasmania, and North Island, New Zealand. Moderate surpluses are expected in an arc across the northern part of the country from the Kimberly Plateau through northeastern Queensland to the coast. The forecast past March is less eventful, with deficits emerging across Northern Territory, scattered through Victoria and New South Wales, and in Tasmania, and New Zealand.
Water deficits are forecast for Missouri, Oklahoma, and Arkansas, as well as in a line extending northeast from Mississippi through Alabama, northern Georgia, western South Carolina, western North Carolina, Virginia, Maryland, and Pennsylvania. Surpluses are expected in southern Idaho, northeastern Nevada, and northwestern Utah.
The forecast for Canada through March indicates water deficits in central Quebec, southern Ontario, southern Newfoundland, and northern reaches of western provinces. Surpluses are forecast across Ontario from the southern Kenora District to Quebec, Manitoba from Hudson Bay reaching southwest to Lake Winnipeg, northwestern Saskatchewan, and southern British Columbia.
The forecast through March indicates scattered moderate water deficits throughout much of Mexico with pockets of exceptional deficits in the south and the Yucatan Peninsula. Deficits will persist in Guatemala and emerge in eastern Jamaica. Surpluses are forecast for eastern Honduras, Nicaragua, Costa Rica, Panama, and Haiti.
Water anomaly patterns will remain much the same in the next six months with shifts in extent and intensity. Deficits are forecast through June in Scandinavia, the Baltics, Western Europe, and Central Europe. Surpluses will persist in Eastern Europe, western European Russia, and southern Spain’s Mediterranean coast.
Drier than normal water conditions will persist in many parts of northern Russia from the White Sea past the Central Siberian Plateau through September. Surpluses will persist in the Ural River watershed in Kazakhstan, and also in the central, northeastern, and eastern parts of the country. Surpluses are forecast to persist in eastern Kyrgyzstan, and moderate deficits in Uzbekistan. An expanse of exceptional deficits between the Irtysh and Yenisei Rivers in Russia is forecast to transition to exceptional surplus from April through June.
Water surpluses are forecast to persist in Southeast China through March but with diminished severity, except in Shanghai and Jiangsu where exceptional surpluses may persist. Deficits will continue to emerge on the Liaodong Peninsula, eastern Sichuan, Shaanxi, Gansu, Ningxia, and eastern Yunnan. Exceptional deficits intermingled with conditions of both deficit and surplus are expected across northern China from central Inner Mongolia west and north into Mongolia. After March Southeast China is forecast to transition to normal conditions and anomalies elsewhere in the country will generally diminish in severity.
Water surpluses are forecast for Laos, central Vietnam, and the Malay Peninsula through March. Exceptional deficits will persist in Cambodia near Tonlé Sap Lake during this period. After March, a transition to water deficits in parts of Malaysia, Indonesia, and Papua New Guinea is forecast, and deficits will continue to emerge through September.
