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: Water surpluses will increase in southern BC
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.
Canada: Water deficits will persist in Ottawa-Gatineau
The forecast through March indicates a pattern of water anomalies similar to the prior three months. Notable changes are as follows: deficits are expected to increase and intensify in southern Saskatchewan and to a lesser extent in southern Alberta; and, moderate surpluses will emerge in southwestern British Columbia and along the length of BC’s coast. Persisting conditions include intense deficits in the Ottawa-Gatineau Region of Quebec and across the border into Southern Ontario.
Canada: Exceptional water deficits to decrease in the Prairie Provinces
Exceptional water deficits are forecast to decrease, though vast blocks will persist. These areas include: Quebec from the Caniapiscau Reservoir to the St. Lawrence River; surrounding Lake Mistassini, QC; Ontario’s eastern border; northeastern Manitoba; the Lower Athabasca River region in Alberta; surrounding Prince George, British Columbia; and, northwestern BC. Intense surpluses will persist from northwestern Saskatchewan reaching west to Fort McMurray, Alberta, and in southeastern BC.
