Significant Flood Outlook Graphic Map

Notice: The SERFC Significant Flood Outlook graphic is intended to provide a general outlook for significant river flooding. It is not intended to depict all small-scale events such as localized flooding and/or flash flooding. This graphic will not depict minor river flooding as this implies only minimal or no property damage with possibly some public inconvenience. Please refer to products issued by local NWS offices for specific details. For a list of NWS offices and their links go to:

When creating the daily Significant Flood Outlook Maps, the HAS forecasters and hydrologists at the SERFC use the 5 day forecast issued by the Weather Prediction Center (WPC), as guidance when making a decision of whether to highlight an area that may receive Significant Flooding.
