A Flash Flood Watch has been issued for the Cannon River area. Parts of the Cannon River Watershed received heavy rainfall amounts overnight last night. City Staff have been working with the National Weather Service (NWS) to evaluate the rainfall amounts and corresponding effect on river levels in the area. NWS staff have predicted additional heavy rains will fall across our region Wednesday evening through Thursday evening. Depending on the amounts of rain and where it falls, the Cannon River at Northfield could rise quickly to flood stage.
NWS professionals have created the attached graph depicting potential rainfall and resulting possible Cannon River levels in Northfield. NWS is still predicting the Cannon River could peak at approximately 897’ on Friday, September 13, 2019. Depending on rainfall, the river could peak even higher. In Northfield, 897’ is considered flood stage. If the river reaches that level, some Northfield properties and park areas along the river would be directly affected.
