The forecast through July indicates that exceptional water deficits across northern Africa will diminish, but intense deficits will persist in Libya, Niger, Egypt, and Sudan. Deficits will downgrade in Gabon and southern DRC but remain severe. Deficits will persist in western Zambia and are expected to be extreme on the Kafue River. Relatively mild deficits are forecast for southern Africa. Intense surpluses will persist in Tanzania, Kenya, northern Uganda, and northern Madagascar.
Canada: Intense water surplus to persist in southern BC
Two transitions stand out in the near-term forecast: a change from water surplus to deficit in northern Quebec, and the emergence of widespread, exceptional surpluses in southeastern British Columbia. Deficits will diminish overall but are forecast along Ontario’s eastern border; in northeastern Manitoba and north of Lake Winnipeg; in northwest Alberta and north and west of Edmonton; around Prince George, BC, and in northwest BC. Surpluses will emerge in eastern Quebec near the mouth of the St. Lawrence River, and will increase along the northern border of Alberta and Saskatchewan.
