Canada: Water surpluses will shrink in S. Quebec

The forecast through August 2019 indicates that water surpluses will shrink in southern Quebec. Some surpluses are forecast near Toronto and Montreal, deficits from Regina to Winnipeg, and intense deficits in southern Vancouver Island. Exceptional deficits will persist along Ontario’s eastern border and in large pockets of Quebec, Manitoba, and Saskatchewan. Surpluses will increase in Newfoundland and Labrador and persist in a large block spanning the northern Alberta-Saskatchewan border.

Canada: Water surpluses to increase from Toronto to Lake Huron

Primarily moderate deficits are forecast across southern Manitoba and Saskatchewan. Intense surpluses will emerge in the Columbia River Basin in British Columbia, and deficits near Vancouver will persist but downgrade.
