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.

The forecast through October indicates some retreat of exceptional water deficits, especially in southern Saskatchewan and Manitoba where deficits are expected to downgrade, becoming mild to moderate. Deficits will shrink in British Columbia around Prince George, though remain exceptional; will downgrade somewhat in Alberta and along Ontario’s eastern border; and will shrink in Quebec but remain widespread. Exceptional surpluses in southern BC will diminish.
Two transitions stand out in the near-term forecast: a change from water surplus to deficit in northern Quebec, and the emergence of widespread, exceptional surpluses in southeastern British Columbia. Deficits will diminish overall but are forecast along Ontario’s eastern border; in northeastern Manitoba and north of Lake Winnipeg; in northwest Alberta and north and west of Edmonton; around Prince George, BC, and in northwest BC. Surpluses will emerge in eastern Quebec near the mouth of the St. Lawrence River, and will increase along the northern border of Alberta and Saskatchewan.
The forecast through April indicates water conditions much the same as in the prior three months, with some overall shrinkage of anomalies in the eastern half of the country. One notable difference is the emergence of widespread intense surplus conditions in southern British Columbia. After April, much of the eastern half of the country will transition to deficit, retaining exceptional deficits in eastern Quebec, central Quebec, and the central Quebec/Ontario border. Deficits in the western provinces will diminish slightly, and intense surpluses will persist in parts of southern BC.
The near-term forecast indicates a pattern of water anomalies much like the prior three months. Widespread surpluses will continue in northeastern Quebec, central Ontario, west of Lake Winnipeg in Manitoba, near Churchill Lake in Saskatchewan and into Alberta, the central border of Alberta and British Columbia, and southeastern BC. Deficit areas include: central Quebec and the Ontario/Quebec border; northwestern Ontario into central Manitoba; and southern Manitoba and southeastern Saskatchewan. After March, surpluses in Quebec and Ontario will transition to deficit.
The forecast for Canada through February indicates that exceptional deficits will shrink in Quebec, though a vast expanse will remain surrounding Lake Mistassini. Deficits will also persist in southern Newfoundland, New Brunswick, northeastern Manitoba, and northern British Columbia. Surpluses are forecast across Ontario from Kenora District in the west to Quebec; Manitoba from Hudson Bay reaching southwest to Lake Winnipeg; northwestern Saskatchewan; and southern British Columbia. After February much of Ontario will transition from surplus to mostly moderate deficit.
The forecast for Canada through January shows that exceptional deficit will persist in central Quebec but the extent of exceptional deficits will shrink in Quebec, southern Nova Scotia, and southern Newfoundland. Moderate deficits will persist in Southern Ontario. Exceptional surpluses are forecast in the southwestern corner of Northern Ontario and in the Columbia River Basin in southern British Columbia. From February through April many areas of eastern Canada will transition to normal, though large pockets of exceptional deficits will persist in Quebec and Ontario, and surpluses will continue to emerge in southern British Columbia.
