Instructions:

River rises are being affected by snow melt from a combination of precipitation and warm temperatures. Changes to the precipitation forecast or the temperature forecast may cause changes to the river forecast. An ice jam is affecting water levels in this area. River forecasts during ice jams are less certain due to many complicated factors. Significant river ice cover can cause large water level fluctuations and flooding with little advanced notice. River ice may also cause gauge observations to be inaccurate. These forecasts are based on observed precipitation as well as forecast precipitation 48 hours into the future. Changes to the rainfall forecast, or any additional rainfall after 48 hours, may cause changes to these river forecasts. A Flood Warning means water levels above flood stage are imminent or may already be occurring. Persons along rivers and streams in the warned area should take immediate precautions to protect life and property. Additional information is available at www.weather.gov. The next statement will be issued Saturday afternoon at 330 PM CST.
