premise: Over 1,600 volunteers registered to help build approximately 65,000 of the 500,000 sandbags to create dikes 20.5 feet (6.2 meters) high to protect the City of Winnipeg, Manitoba in the war against the Red River of the North flood. 700 volunteers answered at the rural municipality of St. Andrews alone. Once sandbags are filled for West St. Paul, St. Andrews, and Selkirk, then frozen culverts must be cleared. The height of the river is expected to be Thursday, and predictions are that it will be less than Flood of the Century of 1997. There is no precipitation in the forecast, and snow in the province should be melted by the end of the week.
hypothesis: Red River will overflow its banks.
