Canada: Intense water deficits to retreat from Ottawa-Gatineau Watershed

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.

The major changes forecast through May are that exceptional water deficits will shrink in Quebec though large pockets will persist, and widespread surpluses in Northern Ontario will transition to deficit. As for major population areas, intense deficits are forecast for Southern Ontario and through southern Quebec; near Vancouver, British Columbia; near Winnipeg, Manitoba; and surrounding Regina, Saskatchewan. Deficits of varying intensity are forecast in many parts of the country. In British Columbia, surpluses will increase in the southeast and transition to deficit in the southwest.

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.

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.

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.
