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.
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.
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.
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.
Exceptional water deficits are expected to nearly disappear in Mexico April through June, with moderate deficits persisting in Chiapas and Tabasco. Severe to exceptional deficits are forecast to emerge in the Baja Peninsula and Sonora and moderate deficits will emerge in Guatemala. From July through September moderate to extreme deficits are forecast to re-emerge in southern Mexico, persist in northern Baja, and emerge in Guatemala, El Salvador, western Honduras, western Nicaragua, northern Costa Rica, and Jamaica.
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 deficits of modest severity are forecast throughout many parts of Mexico over the next six months with pockets of exceptional deficits in Oaxaca, Yucatán, Guerrero, Michoacán, western Jalisco, and Nayarit. Moderate to severe deficits are forecast to persist in western Cuba and emerge in eastern Cuba and in Jamaica through February. Deficits will persist in Guatemala; surpluses will persist in Honduras, Nicaragua, and Costa Rica but may transition to both surplus and deficit.
Regions likely to have significant water deficits for the 12-month period from September 2016 through August 2017 include: the US South; Chile; Scandinavia; northern Africa, southern Somalia, and South Africa; the Middle East; southern India; Cambodia; and northern Russia. Water surpluses are forecast for: southern Minnesota, Nicaragua, Kazakhstan, Bangladesh, western Myanmar, Laos, Vietnam, and Jiangsu and Shanghai, China This watch list is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 6 December 2016.
