Canada: Exceptional water deficits to retreat in Prairie Provinces

Canada: Exceptional water deficits to retreat in Prairie Provinces

The near-term forecast through October indicates a significant retreat of exceptional water deficits in the Prairie Provinces. Deficits will persist in central Quebec and southern Newfoundland, and emerge east of the St. Lawrence River, in New Brunswick, and in southern Nova Scotia. Surpluses are expected to persist in central Manitoba west of Lake Winnipeg, a large block of northwestern Saskatchewan into Alberta, southeastern British Columbia, and near Ottawa and west of Toronto. After October conditions will continue to moderate, though some exceptional surpluses will persist.

Canada: Water surplus in southern ON to persist through September

Canada: Water surplus in southern ON to persist through September

Exceptional water surpluses in southern Ontario west of Toronto are forecast to persist through September, as are exceptional deficits in eastern Ontario and central Quebec. After September moderate drought conditions are expected to persist in northwest Ontario, northern Manitoba, and northern British Columbia. Recent exceptional surplus conditions in Manitoba west of Lake Winnipeg, and in northwestern Saskatchewan into Alberta are expected to continue throughout the forecast period into early 2018.

Canada: Water deficits in central QC & along QC/ON border

Pockets of exceptional water deficits affecting the eastern extents of Ontario and central Quebec are expected to persist in the near-term but subside by September. Recent exceptional surplus conditions in Manitoba, Saskatchewan and Alberta are expected to continue throughout the forecast period into early 2018. Conditions normalize over the remaining regions of Canada by the December through February 2018 period.

Canada: Water surpluses forecast in southern QC, deficits in center & north

Water deficits of varying severity are expected through October in central and northern Quebec, Ontario, northeastern Manitoba, and northern British Columbia and Alberta. These deficits may be exceptional through July in Ontario along the border with Quebec and northeastern Manitoba, and through October across central Quebec. Moderate surpluses are forecast through October in southern Quebec. Surpluses reaching exceptional intensity are forecast through July in northeastern British Columbia; and through October from northwestern Saskatchewan into Ft. McMurray, Alberta, and northwest of Lake Winnipeg in Manitoba.

Canada: Widespread water deficits forecast in QC, surpluses southern BC, AB

Canada: Widespread water deficits forecast in QC, surpluses southern BC, AB

Widespread severe to exceptional water deficits are forecast through September in much of Quebec, along its border into Ontario, around Hudson Bay in Manitoba, and in central and northwestern regions of Alberta and British Columbia. Large pockets of exceptional surpluses are expected to persist through June in southeastern British Columbia, northwestern Saskatchewan into Alberta, and in central Manitoba. These surpluses are expected to diminish after June. 

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.
