ABRFC Significant Flood Outlook

The Significant Flood Outlook Potential identifies areas where significant river flooding is possible, likely or imminent up to five days in the future, using up to 120 hours of forecast precipitation. ABRFC defines significant river flooding as flooding in the moderate, major, or record flood categories. In general, flooding of moderate category or greater will result in conditions that adversely affect roads, residential, commercial, industrial, and/or agricultural areas and may require evacuation of people and/or livestock.

This graphic will not depict minor river flooding as this implies only minimal or no property damage with possibly some public inconvenience. The FOP is not intended to depict all small-scale events such as localized flooding and/or flash flooding. Please refer to products issued by local NWS offices for official river forecasts and warnings.

The FOP comes in two scales -- National and RFC-wide. Click on the map perimeter (or click here) to view the National Significant Flood Outlook.

Within the map below, click on any area of interest to scale down to the corresponding local NWS office river forecast page. The official forecasts at specific points on these local NWS office pages use 12 hours of forecast precipitation, thus discrepancies may appear between official forecasts and the outlook areas shows on this page.
