Exceptional deficits across Africa will downgrade in size, but remain in pockets of northwestern, central, and south-central regions of the continent. Surpluses are expected to continue along the Sahel. 

Widespread exceptional deficits in South America will mostly dissipate, though some anomalies will remain in regions of Brazil and the Southern Cone. 

Exceptional deficits in the Northern Territories, West Coast, and Prairie Provinces will downgrade in size, but remain in pockets of the regions. Surpluses of varying intensity are expected in several regions of Nunavut.

The forecast for February 2025 expects significant water deficits for the 12-month period of November 2024 through October 2025 in northwestern and central Africa, southwestern U.S., eastern Europe, and central South America. Areas expected to experience surplus include central Africa, northern Canada, and Central America.

In this analysis, we examine the destructive 2024 floods in Yemen and revisit WSIM forecasts which predicted them.

Surpluses will remain in northern areas of Queensland, as well as some isolated areas of Northern Territory and Western Australia. 

Widespread exceptional deficits in the Middle East will resolve in some areas, but remain in some portions of Saudi Arabia, Oman, and Iran. Moderate to severe surplus is anticipated in some coastal regions along the Red Sea. 

Surpluses will remain along the Sahel. Exceptional deficits will persist in northwestern, central, and eastern portions of Africa.  

Exceptional deficits will continue in northwestern Mexico. Severe to exceptional surpluses will persist in much of Central America.
