Advanced Hydrologic Prediction Service 90 Day Probabilistic Forecast... This is the 90 day probabilistic forecast for locations along the Kankakee River Basin in northern Indiana and for the Saint Joseph River Basin in northern Indiana and southern Michigan. In the table below the 95 through 5 percent columns indicate the chance the river could rise to or above the listed stage levels in the next 90 days. For example, the Kankakee River at Davis, Indiana has a flood stage of 10 feet. In the next 90 days there is a 10 percent chance the river will rise to or above 9.3 feet. The St. Joseph River at South Bend, Indiana has a flood stage of 5.5 feet. In the next 90 days there is a 25 percent chance the river will rise to or above 4.5 feet. Chance of exceeding stages at specific locations ...Valid March 8 2025 - June 7 2025 Kankakee River Basin...

By providing the complete range of probabilities, the level of risk associated with long-range planning decisions can be determined. These probabilistic forecasts are a part of NOAA National Weather Services Advanced Hydrologic Prediction Service. Additional supportive data and explanations are available on AHPS at www.weather.gov/iwx, under Rivers and Lakes. ...Snow Cover/Soil Conditions... As of March 8th, little if any snow was remaining over the area. Soil Moisture remained below to much below normal. ...Weather Outlook... ENSO is forecast to transition from a weak La Nina to a Neutral pattern during this outlook period. There is not a discernible signal for either above or below normal temperatures. CPC is leaning above normal for total rain outlook. Normal rainfall amounts through the middle of May are near 9 inches. ...River Conditions... River conditions remained below action stage and well below flood stage. ...Overall Flood Risk... Given the dry soil state with below normal rainfall, the overall flood risk is expected to be below normal into May. ...Flood Terminology... The term minor flooding is used to indicate minimal or no property damage. However, some public inconvenience is possible. The term moderate flooding is used to indicate the inundation of secondary roads. Transfer to a higher elevation may be necessary to save property. The term major flooding is used to indicate extensive inundation and property damage, usually characterized by the evacuation of people and livestock and the closure of both primary and secondary roads. The next long-range probabilistic outlook will be issued in February 2026 for the Kankakee and Saint Joseph River basins. $$
