The ISciences Global Water Monitor and Forecast Watch List provides monthly reports of data collected by our Water Security Indicator Model (WSIM), which monitors and forecasts water anomalies on a global basis.
The forecast for April 2024 expects significant water deficits for the 12-month period of January 2024 through December 2024 in South America, northeastern Africa, and the Middle East. Areas expected to experience surplus include eastern to eastern Africa, northern Australia, Europe, and Southeast Asia.
The forecast indicates that exceptional deficits will persist in northwestern regions of China, but lessen in size in northern and northeastern China. Surpluses occurring in Tibet are also expected to remain but diminish in size.
The forecast indicates that deficits will persist throughout Mainland Southeast Asia, but decrease in intensity, becoming mostly moderate to severe anomalies. Intense surplus is expected to expand throughout Maritime Southeast Asia, particularly in central Indonesia, Papua, and Papua New Guinea.
The forecast through July indicates that exceptional water deficits in northern Quebec will shrink though vast areas will persist. Moderate surpluses are forecast in the Gatineau River Watershed north of Ottawa. Deficits will increase in Southern Ontario but a pocket of moderate surplus will persist west of Toronto. Surpluses will increase in southeastern British Columbia and will be exceptional.
The forecast through November indicates some moderate water deficits around Montreal and between Toronto and Ottawa, and severe deficits southeast of Winnipeg. A vast arc of exceptional deficit will persist in northern Quebec from Lake Mistassini to the province’s eastern border. Intense deficits will also persist in central and northeastern Manitoba and central and northwestern Alberta. Surpluses are forecast from north-central Alberta into northwestern Manitoba.
