  • The purpose of this SFWRS and the associated flood inundation map is to communicate flood risk based on best available information at the time of map development. The AHPS flood inundation map that is used for the SFWRS has been compiled using the best information available and is believed to be accurate; however, its preparation required many assumptions. Actual conditions during a flood event may vary from those modeled in the map. The limits of flooding shown should only be used as a guideline for emergency planning and response actions, and not for navigation or permitting or other legal purposes. Actual areas inundated will depend on specific flooding conditions.
  • If this SFWRS will be used in conjunction with National Weather Service (NWS) river forecasts, the user should be aware of additional uncertainties that may be inherent or factored into NWS forecast procedures. The NWS uses forecast models to estimate the quantity and timing of water flowing through selected stream reaches in the United States. These forecast models (1) estimate the amount of runoff generated by precipitation and snowmelt, (2) simulate the movement of floodwater as it proceeds downstream, and (3) predict the flow and stage (water-surface elevation) for the stream at a given location (AHPS forecast point) throughout the forecast period (every 6 hours and 3 to 5 days out in many locations).
