NOTE: Forecasts are issued routinely year-round.
River forecasts for this location take into account past precipitation and the precipitation amounts expected approximately 48 hours into the future from the forecast issuance time.
National Water Model Hydrograph
Official NWS streamflow forecasts are produced by NWS hydrologic forecasters for river gauge locations using hydrologic models which are calibrated to that location. This process considers additional guidance and information, including local expertise and experience, to produce the best forecast possible. The NWM output provides supplemental guidance to NWS forecasters and should not be considered an official NWS river forecast.
Flood Impacts
- 51 - Large amounts of property damage can be expected. Evacuation of many homes and businesses becomes necessary. Highway 60 in Smithland closes.
- 40 - Minor flooding occurs affecting mainly bottomland and surrounding and low lying areas.
