The forecast through July indicates that intense water deficits observed in Mexico will downgrade considerably. Severe to extreme deficits are, however, expected in Baja and along the Pacific Coast from Sinaloa through Guerrero. Severe deficits are forecast for Tabasco and moderate deficits elsewhere around the Gulf of Mexico. Moderate deficits are also expected in Guatemala, El Salvador, Haiti, and western Cuba.
The forecast through June indicates water deficits in Baja, Mexico, coastal Sonora, southern Chihuahua, the Pacific Coast from southern Sinaloa through Chiapas, and the Yucatan Peninsula. Areas of surplus include Coahuila, the southern border of Chihuahua and Sonora, and pockets in the center of the country. Some moderate deficits are expected Central America, Haiti, and Dominican Republic.
The forecast through May indicates a patchwork of water anomalies. In Mexico, moderate to extreme deficits are forecast in Nayarit, Guerrero, Chiapas, and Yucatan. Conditions of both deficit and surplus are forecast from southern Durango southeast through Morelos. Regions forecast with surpluses include northern Coahuila, Nuevo León, southern Tamaulipas, eastern San Luis Potosí, Distrito Federal, and northern Oaxaca into central Veracruz. Exceptional deficits are expected in western Panama, and moderate deficits in Dominican Republic.
The September Outlook indicates that intense heat anomalies which have dominated Central Europe for the past month are expected to moderate overall. Exceptionally warmer than normal temperatures will prevail in Madagascar. Much drier than normal conditions are forecast in India along its southern Arabian Sea coast and also in Ethiopia's central Highlands.
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.
In the next few months water deficits in Baja, Mexico will remain intense, with exceptional deficits emerging in the south. Extreme to exceptional deficits are also forecast for Sonora, Sinaloa, Durango, Nayarit, along with deficits slightly less severe in Chihuahua. Surpluses of varying severity will continue to emerge in pockets of southern Mexico leading into northern Guatemala and Belize, where conditions may be extreme. Severe to exceptional surplus is forecast for Honduras, Nicaragua, Costa Rica, and Jamaica.
Regions forecast to have significant water deficits for the 12-month period from December 2017 through November 2018 include: the US West, Southwest, and South Atlantic States; southern Venezuela; Uruguay; northeastern Argentina; Finland; northern Africa and Gabon; and southern Iraq. Areas with a forecast of significant water surplus include: the Ohio River Valley and western Montana (US); Paraguay; Tanzania and Ethiopia; Ireland; Central and Eastern Europe; and European Russia. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 7 March 2018.
In the next few months, exceptional water deficits will retreat in northwestern Mexico but persist in southern Baja and emerge in Nayarit. Severe deficits are forecast in the north-central states and along the Rio Grande. Some pockets of surplus are expected in southern Mexico and northern Guatemala, and more intense surpluses in Honduras, Nicaragua, and Costa Rica. Severe deficit is forecast for western Cuba and the Bahamas. After April, deficits will downgrade in southern Baja and surpluses will emerge in western Mexico from Durango into Oaxaca.
Regions forecast to have significant water deficits for the 12-month period from November 2017 through October 2018 include: California, Nevada, Arizona, Louisiana, Arkansas, Mississippi, Venezuela, French Guiana, Gabon, Mongolia, and Tasmania. Areas with a forecast of significant water surplus include: Ireland, Poland, European Russia, Tanzania, and Philippines. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 6 February 2018.
Intense water deficits across northwestern Mexico are expected to moderate from January through March, but moderate to severe deficits will spread in the north-central states. Intense deficits will emerge in Nayarit, Jalisco, Colima, and Michoacán. Deficits in western Cuba will moderate. Significant surpluses are expected to persist in Honduras, Nicaragua, northern Costa Rica, and Jamaica. After March, deficits are forecast in northern Mexico, moderate surpluses along the southwestern coast, and surpluses in Central America will diminish.
