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.
For the next three months, water surpluses are forecast in Mexico for northern Coahuila, along Sinaloa’s northern coast, and from southern Durango through Mexico City. Deficits are expected in the northern Yucatan and scattered small pockets throughout the south. Deficits along the Rio Grande in Chihuahua will moderate. Deficits in Cuba and Hispaniola will become mild, but intense deficits will emerge in eastern Jamaica.
Regions forecast to have significant water deficits for the 12-month period from October 2018 through September 2019 include: Quebec (Canada), Finland, Venezuela, Somalia, South Africa, India, Thailand, Cambodia, and Australia. Areas with a forecast of significant water surplus include: Texas (US), Paraguay, Uruguay, Tanzania, and China. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 1 February 2019.
For the next three months, water surpluses will persist in northern Coahuila, Mexico, and along a diagonal from southern Durango through Mexico City, broken by a pocket of exceptional deficits in southern Puebla, and continuing into northern Oaxaca. Intense surpluses are forecast in Nicaragua. Areas of deficit include: the Rio Grande in Chihuahua, northern Yucatan, western Panama, Jamaica, Haiti, and Dominican Republic.
The forecast through January indicates moderate to severe deficits in the northern Yucatan Peninsula and scattered throughout the southern states, and severe deficits along the Rio Grande in Chihuahua. Surpluses are forecast for northern Coahuila; a path from southern Durango through Mexico City; and, southern Guatemala, El Salvador, southern Honduras, Nicaragua, and northern Costa Rica. Intense deficits are forecast for Jamaica.
The forecast through December indicates pockets of intense water deficit in Mexican states along the southern Gulf of Mexico and across to the Pacific. Moderate deficits are forecast for Yucatan and Mexico’s southern Pacific coast. Surpluses will persist in Coahuila, and will increase in northern Sinaloa, western Chihuahua, and from Zacatecas through Mexico City. Surpluses are expected in eastern Guatemala and eastern Costa Rica. Deficits in Cuba will moderate.
Though water deficits in the region are expected to diminish and downgrade, the forecast through November indicates severe to exceptional deficits for Mexico’s northern Baja Peninsula and in states along the southern Gulf and across to the Pacific. Primarily moderate deficits are forecast for northern Central America and surpluses are expected in Costa Rica. Extreme deficits are forecast eastern Jamaica.
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.
Intense water surpluses are forecast to persist through May in Honduras, Nicaragua, northern Costa Rica, and Jamaica. In the near-term, exceptional deficits across northwestern Mexico will moderate but severe deficits will emerge further south coast-to-coast from Jalisco through Veracruz and also in Oaxaca. Deficits in western Cuba will moderate. After February intense deficits will emerge in southern Baja and Nayarit, Mexico but much of southern Mexico will return to nearly normal water conditions with scattered pockets of surplus.
