Canada: Intense water deficits to persist in northern QC

Through January 2020 nearly normal conditions are forecast for most major metropolitan areas with moderate surpluses around Montreal and deficits near Regina, Saskatchewan. Exceptional deficits will persist in a vast portion of central and northern Quebec and large blocks in northern Manitoba and Alberta. Surpluses are expected in the southern Columbia Mountains of British Columbia.

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.

Exceptional water deficits are expected to decrease but will persist in many areas, including along Ontario’s eastern border. Surpluses are expected northwest of Toronto, and moderate deficits from Peterborough to Ottawa. In Quebec, deficits will be extreme around Sherbrooke. Severe deficits are forecast for southern Manitoba. Deficits will be intense in the Upper Athabasca and Lower Peace River Regions of Alberta, and surrounding Prince George, BC. Surpluses will increase in southern BC and will be exceptional around Kamloops and Kelowna.

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.

Water deficits are forecast for much of the eastern half of the country and will increase on the Ontario/Quebec border corridor. Widespread, intense surpluses will emerge in southeastern British Columbia (BC), particularly surrounding Kamloops and Kelowna. Intense deficits will continue to emerge around Prince George, BC. Deficits in the Upper Athabasca Watershed of central Alberta will intensify, becoming exceptional. Exceptional surplus conditions will persist from Fort McMurray, Alberta to Churchill Lake, Saskatchewan, and around Fort St. John in the Peace River Region of northeastern BC.
