The forecast through September indicates that water deficits will downgrade in the Levant but remain intense in West Bank and Lebanon, and deficits will intensify on the Arabian Peninsula. In Turkey, deficits will downgrade and shrink somewhat but much of Turkey will continue in moderate to severe deficit with some pockets of greater intensity. Exceptional deficits will persist in southern Iraq, and severe deficits west of the Euphrates River. In Iran, deficits will increase and become more intense.
Over the next few months, significant water deficits will emerge in southern Mexico including Michoacán, Guerrero, Puebla, Veracruz, Oaxaca, Tabasco, and Chiapas. Exceptional deficits will also reach into Central America, emerging in Guatemala, El Salvador, and western Honduras. Deficits will downgrade somewhat in western Cuba but intensify in Haiti and the Dominican Republic, and Jamaica will transition from surplus to deficit.
Exceptional water deficits will shrink and downgrade across North Africa and along the Red Sea but deficits will remain widespread and intense. Intense deficits are also forecast for western Ethiopia, southern Gabon, northwestern Botswana, central Zambia, and western Madagascar. Exceptional surpluses will persist in East Africa; extreme surpluses are forecast for the conjoined borders of Cameroon, Central African Republic, and Republic of the Congo; and surpluses of lesser intensity are forecast for westernmost Democratic Republic of the Congo.
Regions forecast to have significant water deficits for the 12-month period from April 2018 through March 2019 include: southern Mexico, northern Brazil, North Africa, Europe, and Afghanistan. Areas with a forecast of significant water surplus include: Montana and Idaho (US), Tanzania, Kenya, Uganda and Bangladesh. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 10 July 2018.
The July Outlook indicates exceptionally drier than normal conditions for most of southern Mexico into Central America. Much warmer than normal temperatures are forecast for Ireland and western United Kingdom, as well as many other parts of the world.
Moderate water deficits, punctuated by more intense pockets, are expected across a large portion of the east and southeast including the Murray-Darling Basin, scattered across the north, and in the southwest tip of the country. Deficits are expected to be intense in Tasmania, pockets along the southeast coast, the southwest tip, Darwin and the Daly River region, and along the southern shore of the Gulf of Carpentaria. Intense deficits are forecast for New Caledonia.
The forecast indicates a transition away from widespread, intense water surplus to deficit. Surpluses are forecast, however, for parts of Myanmar, northern Laos, northwestern Vietnam, eastern Cambodia, central Philippines, and East Nusa Tengara. Intense deficits will emerge in southernmost Thailand, and spread in Malaysia and northern Sumatra. Deficits of varying intensity are expected to emerge throughout Indonesia and may be extreme in West Nusa Tengara and Timor-Leste. Deficits in Papua New Guinea will downgrade but remain severe.
Exceptional water deficits will diminish over the next few months, but large pockets are forecast for Brazil in Acre, Rondônia, Pará, Tocantins, Goiás, Minas Gerais, Mato Grosso do Sul, and São Paolo. Intense deficits elsewhere include: Venezuela east of Lake Maracaibo and near the border with Guyana; southern Bolivia; and along a path beginning south of Lima, Peru, through northern Chile. Deficits in Argentina will moderate and surpluses will emerge in northern Buenos Aires Province.
Water surpluses will shrink in European Russia, transitioning to both deficit and surplus the Northern European Plain. Widespread deficits along the Pechora Sea through Yamal Peninsula and into the Central Siberian Plateau will retreat considerably. Surpluses in the Upper Ob and Tom River regions will diminish but remain widespread. Deficits will increase in the Bolshoy Yugan River watershed in the Middle Ob. Surpluses will persist in northern Kazakhstan, and deficits are forecast for Turkmenistan, eastern Uzbekistan, central Kyrgyzstan, and Tajikistan.
Exceptional water deficits are expected to decrease but will persist in many areas, including along Ontario’s eastern border. Surpluses are expected northwest of Toronto, and moderate deficits from Peterborough to Ottawa. In Quebec, deficits will be extreme around Sherbrooke. Severe deficits are forecast for southern Manitoba. Deficits will be intense in the Upper Athabasca and Lower Peace River Regions of Alberta, and surrounding Prince George, BC. Surpluses will increase in southern BC and will be exceptional around Kamloops and Kelowna.
