How to Interpret this Map

The Runoff Risk Advisory Forecast map shows day-to-day risk of runoff occurring across Michigan using National Weather Service forecast methods that consider precipitation, soil moisture, and individual basin characteristics. Data is typically updated each day in the morning. You can view when the last update was made in the lower left-hand corner of the map. Keep in mind that there is more uncertainty to the rainfall and subsequent runoff predictions as you look further ahead.
