The forecast through June indicates water surpluses near Toronto and Calgary, and deficits for Winnipeg, Regina, and Vancouver Island. Deficits will shrink in Quebec but remain widespread in the north, and surpluses will emerge in the Gatineau River Watershed. Surpluses will increase in southeastern British Columbia.
Canada: Water surplus to persist from Lake Huron to Toronto
The forecast through September indicates that moderate water surpluses will persist from Lake Huron to Toronto but surpluses in southern Quebec, including the Gatineau River Watershed and Montreal, will nearly disappear. Moderate to extreme deficits will persist in southern Manitoba. Exceptional deficits are expected in southern Vancouver Island, British Columbia, and surpluses in the southern Columbia Mountains.
