Australia & New Zealand: Surpluses ...

The forecast indicates that extreme to exceptional surpluses in northern Australia will diminish, though will still remain present in some regions of Northern Territory. Exceptional deficits across the continent will similarly dissipate, though severe deficits are expected along the southern coast of Victoria.

Canada: Water deficits forecast to persist in Ottawa-Gatineau Watershed

Canada: Water deficits forecast to persist in Ottawa-Gatineau Watershed

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.

Canada: Water deficits to downgrade in SK & MB

Canada: Water deficits to downgrade in SK & MB

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.

Canada: Intense water surplus to persist in southern BC

Canada: Intense water surplus to persist in southern BC

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.

Canada: Water surpluses continue to emerge in southern British Columbia

Canada: Water surpluses continue to emerge in southern British Columbia

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.

Canada: Extreme water surpluses to persist near Ottawa

Canada: Extreme water surpluses to persist near Ottawa

While the forecast for Canada will remain a patchwork of water anomalies, the most noticeable difference in the near-term is the widespread emergence of surplus conditions in Quebec and the slight downgrade of deficits west of Hudson Bay. Surpluses may be extreme near Ottawa. Significant deficits are forecast through January or longer in Jamésie, Quebec; the northern border between Quebec and Ontario; the southeast and southwest shores of Hudson Bay; and northwestern Ontario into central Manitoba. After January near-normal water conditions are forecast for large portions of eastern Canada.

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.
