Canada: Water surpluses will shrink in S. Quebec

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.

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.

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.

The forecast through April indicates exceptional water deficits across Quebec from Hudson Bay into central Labrador, and exceptional deficits in the Ottawa-Gatineau region, northern New Brunswick, and around Fortune Bay on the Island of Newfoundland. Moderate to extreme deficits will persist along Ontario’s eastern border; surpluses are forecast around Toronto. Intense deficits are expected in southern Saskatchewan and the Middle and Upper Reaches of the Athabasca River in Alberta. Surpluses are forecast in southern British Columbia and severe deficits in southern Vancouver Island.

Canada: Water surpluses to emerge in much of Northern Ontario

Through December, exceptional water deficits in the east will shrink somewhat, and moderate to severe surpluses will emerge in much of northern Ontario with intense deficits in the northwest. Deficits will diminish considerably in the southern portions of the Prairie Provinces, though moderate deficits will linger in southern Manitoba and will emerge along the North Saskatchewan River. Elsewhere in the west the pattern of anomalies will remain much the same as in the prior three months.
