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.

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.
The June Outlook indicates much warmer than normal temperatures (40+ years return period) blanketing a large block of Northeast China and stretching across the border well into Russia. Much of Europe is forecast to be warmer than normal, as well as many parts of Indonesia, while much cooler temperatures will prevail in parts of Central Africa. Conditions are expected to be much wetter than normal for several African nations along the Atlantic near the equator.
Mexico, Central America, & the Caribbean: Water deficits forecast for southern Mexico, surpluses in Nicaragua
Water deficits of varying severity are forecast throughout much of Mexico from November through January, with pockets of exceptional deficit in Oaxaca. Deficits will persist in Guatemala, and surpluses are forecast in eastern Honduras, Nicaragua, and northern Costa Rica. From February through April deficits in across northern Mexico will diminish, but moderate to exceptional deficits will persist in the southern states of Michoacán, Guerrero, Oaxaca, and parts of the Yucatán. Surpluses will persist in parts of Honduras and Nicaragua.
The October Outlook indicates a large expanse of exceptionally warmer than normal temperatures forecast from Quebec into Newfoundland and Labrador, Canada, and coastal West Africa, along with widespread significant warm anomalies in Western Europe, Russia, and Southeast Asia. Exceptional dry anomalies are forecast for Guinea-Bissau and western Guinea. Areas with a forecast of wet anomalies include Colombia, Peru, Gabon, Java, and northern Australia.
Deficits on the Baja Peninsula are forecast through October, with some abatement in August. Deficits will continue to emerge in southern Mexico through April. Surpluses are expected in northeastern Sonora, Mexico, northern Costa Rica, and eastern Panama through October. Deficits are forecast to emerge in Haiti. From November on moderate deficits will continue to emerge in southern Mexico, Guatemala, and El Salvador.
Water deficits are forecast to persist on the Baja Peninsula through September with greatest extent and severity in July. Deficits are forecast in southern Mexico during this period and are expected to be of exceptional severity along the southern Gulf of Mexico in Veracruz, Tabasco, and Oaxaca. Deficits are also forecast in Guatemala and El Salvador, Jamaica and Haiti, and after September may emerge in Belize, Honduras, western Nicaragua and eastern Panama.
