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.
Canada: Water deficits forecast near Winnipeg, surpluses near Toronto
The forecast through October indicates that conditions of water surplus in southern Quebec and deficit in southern Alberta and Saskatchewan will normalize. Forecasts for metropolitan areas include surpluses near Toronto; deficits around Winnipeg; normal conditions near Quebec City, Montreal, Ottawa, Regina, Saskatoon, and Calgary; and near-normal conditions in Vancouver. Intense deficits will persist in large pockets of Quebec, Manitoba, and Alberta.
Canada: Water surplus to persist from Lake Huron to Toronto
The forecast through September indicates that moderate water surpluses will persist from Lake Huron to Toronto but surpluses in southern Quebec, including the Gatineau River Watershed and Montreal, will nearly disappear. Moderate to extreme deficits will persist in southern Manitoba. Exceptional deficits are expected in southern Vancouver Island, British Columbia, and surpluses in the southern Columbia Mountains.
Canada: Water surpluses will shrink in S. Quebec
The forecast through August 2019 indicates that water surpluses will shrink in southern Quebec. Some surpluses are forecast near Toronto and Montreal, deficits from Regina to Winnipeg, and intense deficits in southern Vancouver Island. Exceptional deficits will persist along Ontario’s eastern border and in large pockets of Quebec, Manitoba, and Saskatchewan. Surpluses will increase in Newfoundland and Labrador and persist in a large block spanning the northern Alberta-Saskatchewan border.
Canada: Water surpluses to increase from Toronto to Lake Huron
The forecast through July indicates that conditions from the westernmost point of the Ottawa River stretching east to the Gulf of St. Lawrence will transition out of exceptional water surplus to milder anomalies, while conditions around Montreal and near Ottawa transition to moderate surplus, and surpluses from Toronto to Lake Huron increase and intensify. Deficits will cover much of the nation, with intense deficits on Vancouver Island and surpluses in southeastern British Columbia.
