As one storm system moves out of the Red River Valley region Monday night and Tuesday, another potent storm system is forecast to move into the region Wednesday. This storm has the potential to produce heavy rain across the region, which would heighten the river flooding in the southern Red River Basin. Since late winter the southern Red River Valley has been consistently receiving moderate to locally heavy precipitation, increasing soil moisture there. The 2 to 3 inches of rain that fell late last week pushed several area rivers to flood stage.
Since late May, 2 to 4 inches of rain has fallen along and south of a line from Valley City, to Hillsboro North Dakota, to Thief River Falls and Warroad Minnesota. North of that line, generally 1 to 2 inches of rain has fallen the past 2 weeks. With the wet conditions in the far south, any additional heavy rain would likely run off into the area rivers, possibly increasing crest levels or prolonging the period of high water.
At this time it is too early to tell exactly how much rain may fall. Preliminary forecasts show that another 1 to 3 inches of rain may fall in the Red River basin. Depending on how fast, and how widespread the heavy rains are, will determine how high rivers may rise.
