National Weather Service Flood Forecasts

On March 23, 2023, the National Weather Service provided an updated flood forecast for the St. Croix River, which indicated the probability of a major flood event this year. A major flood event is triggered when the river reaches an elevation of 689’, which has an 11% chance of occurring in any given year. Considering the current snow pack conditions throughout the state, the prediction for this year is 80%.

The National Weather Service's predictions remain largely unchanged from two weeks ago, but do include a small uptick in greater flood risk.  The current forecast for potential severe river flooding starts the week of April 3 and runs through the middle of May. Click on the National Weather Service link above to view the short-term flood probability graph that estimates the flood risk for week periods in the short term (two months).

Please remember that predicting this far out is highly variable based on a number of conditions.  At the same time, residents and property owners should start to prepare for a potential major flood event. Please click on the March 14, 2023 link above for flood preparation suggestions. 

The city will begin flood preparations on March 27, which includes filling and taking requests from property owners for sandbags. Delivery of sandbags will be based on river levels March 27-March 31 and the ability to fulfill requests. The city will try to accommodate all requests, but cannot guarantee sandbag availability on a given date. Please contact City Hall if you have specific questions regarding potential flooding.
