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.
Regions forecast to have significant water deficits for the 12-month period from September 2018 through August 2019 include: Quebec (Canada), Chile, Finland, Albania, northern Africa, India, western Cambodia, and southeastern Australia. Areas with a forecast of significant water surplus include: Texas and Pennsylvania (US), Paraguay, western Tanzania, Tomsk and Kemerovo (Russia), and Heilongjiang (China). This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 7 December 2018.
The near-term forecast indicates significant water deficits for southern Mexico which may be exceptional in Puebla, Veracruz, Oaxaca, Tabasco, Chiapas, and Campeche. Surpluses will emerge in Sonora. Deficits are also forecast for northern Central America, with surpluses in the southern nations. Deficits will spread and intensify somewhat in Haiti and the Dominican Republic, and downgrade to mild in western Cuba. Jamaica will transition to extreme deficit.
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.
Mexico will transition away from significant water deficits in the northwest but widespread, intense deficits will emerge across the south and in the east. Deficits may be exceptional in Puebla, Veracruz, Oaxaca, Tabasco, and Chiapas. Surpluses are forecast to emerge in northeastern Sonora. In Central America surpluses will shrink considerably but will persist in eastern Honduras and Nicaragua, and will emerge in Panama. Deficits are forecast for Guatemala, El Salvador, and western Honduras. Deficits of varying severity are also forecast for much of the Caribbean.
In the next few months water deficits in Baja will downgrade somewhat. Moderate deficits are forecast for Chihuahua, Coahuila, Tamaulipas, central Mexico, and along the Gulf from Veracruz into Yucatan. Surpluses in Central America will shrink considerably. Intense surpluses are forecast for Jamaica; deficits are forecast for Haiti and Dominican Republic. After July, intense deficits will emerge in southern Mexico and northern Central America.
Regions forecast to have significant water deficits for the 12-month period from February 2018 through January 2019 include: Brazil, southern Venezuela, Libya, Egypt, Gabon, Finland, Saudi Arabia, and Afghanistan. Areas with a forecast of significant water surplus include: Idaho and western Montana (US), southeastern British Columbia (Canada), Tanzania, Kenya, Spain, Hungary, southern Romania, and eastern Ukraine. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 9 May 2018.
Though water deficits are forecast for Mexico over the next six months, they are expected to be primarily moderate, a significant improvement over the prior three months. Through July deficits are forecast in northwestern Mexico; scattered down the Pacific coast and central Mexico; in Yucatan, Tabasco, and Chiapas; and southern Guatemala. After July deficits will continue to emerge in Baja California, Mexico’s southern states, and northern Central America. Some modest surpluses are forecast to emerge in the north along the border of Sonora and Chihuahua.
