Canada

Canada: Water deficits persist in Quebec

Canada: Water deficits persist in Quebec

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.

Canada: Water deficits forecast in Quebec, surpluses in southern British Columbia

Canada: Water deficits forecast in Quebec, surpluses in southern British Columbia

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.

The outlook for Canada through December indicates that, overall, the extent of exceptional water deficits will shrink, though a span across central Quebec will persist until March. Deficits of varying severity are forecast for most of Ontario and Quebec. Surpluses are forecast in the southwestern corner of Northern Ontario from Kenora north which are expected to persist through March. Surpluses are also forecast for southern British Columbia near Kamloops and the Peace Country region of Northeast British Columbia through March.

Canada: Moderate water deficits forecast for southeastern ON

Canada: Moderate water deficits forecast for southeastern ON

The outlook for Canada indicates large pockets of exceptional water deficits persisting in northern Manitoba and central Quebec through November which will diminish in extent and severity thereafter. Mostly moderate deficits are expected in southeastern Ontario from London to Ottawa through November. Surpluses are forecast to emerge in southwestern Ontario and persist through February. Surpluses are also forecast for southern British Columbia through May.

Canada: Water deficits persist in northern MB, ON, central QB

Canada: Water deficits persist in northern MB, ON, central QB

The outlook for Canada indicates a predominance of water deficits, with large pockets of exceptional deficits persisting in northern Manitoba and central Quebec through October. Deficits will emerge in central Ontario during this time and surpluses will persist in northwest Saskatchewan and across the border into Alberta. By November deficit conditions throughout the country are forecast to ameliorate, though large areas of moderate deficits will remain. Surpluses will continue to emerge in southern British Columbia.

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
