The near-term forecast through November indicates a significant retreat of exceptional water deficits in the Prairie Provinces. Deficits will persist in northeastern Manitoba and are forecast for much of Alberta, where they may be more intense north of Banff National Park in the southwest and may persist through February 2018 or longer. Surpluses in Southern Ontario north of Kitchener and in Ottawa are expected to diminish, and deficits are forecast for much of Northern Ontario. Deficits will persist in New Brunswick, and emerge in Quebec east of the St. Lawrence River.
