The forecast through September indicates widespread water deficits throughout many regions of the Canadian provinces, exceptional in many areas in the east including Ottawa, Montreal, and Quebec City, and moderate to exceptional in the southern regions of the Prairie Provinces.
Canada: Intense water deficits to retreat from Ottawa-Gatineau Watershed
The forecast through June indicates that exceptional deficits will retreat from Quebec’s Ottawa-Gatineau Watershed; surpluses in Northern Ontario will transition to deficit; and deficits in the Middle Reaches of the Athabasca River Watershed in Alberta will become exceptional. Primarily moderate deficits are forecast across southern Manitoba and Saskatchewan. Intense surpluses will emerge in the Columbia River Basin in British Columbia, and deficits near Vancouver will persist but downgrade.
Canada: Water deficits in Ontario and Quebec
The outlook for Canada through December indicates that, overall, the extent of exceptional water deficits will shrink, though a span across central Quebec will persist until March. Deficits of varying severity are forecast for most of Ontario and Quebec. Surpluses are forecast in the southwestern corner of Northern Ontario from Kenora north which are expected to persist through March. Surpluses are also forecast for southern British Columbia near Kamloops and the Peace Country region of Northeast British Columbia through March.
Canada: Water deficits through September in northern MB, eastern ON, & central QB
The outlook for Canada indicates large pockets of exceptional water deficits through September in northern Manitoba, eastern Ontario, and central Quebec, along with deficits of generally lesser severity in British Columbia and the Prairie Provinces. Surpluses are forecast northwest of Quebec City, on the southern shore of Hudson Bay, and in northern Saskatchewan. From October on, deficits across the country are forecast to diminish and surpluses will emerge in southern Ontario and northern Quebec.
