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.
