The National Weather Service (NWS) has responsibility for the issuance of river forecasts and flood warnings. The NWS Newport/Morehead City office has hydrologic responsibility for 5 forecast points on streams and rivers covering anarea of eastern North Carolina.

To issue these river forecasts, local NWS offices rely upon forecast guidance generated by a regional NWS River Forecast Center (RFC). The RFCs use complex hydrologic computer models to forecast rivers. NWS Newport/Morehead City is serviced by the Southeast River Forecast Center in Peachtree City GA (SERFC) .

Most of the forecast points in the NWS Newport/Morehead City area have telemetered river gage equipment. The U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers (COE) own and/or maintain the vast majority of these river gages.

The forecasts of river stages is generated by complex computer models at the RFCs which incorporate many factors. The local NWS offices receive these river stage forecasts from the RFCs and generate public products under several headings:

Precipitation data is vital to river forecasting. Local NWS offices must supply the RFCs with precipitation data to input into their computer models. The SERFCprecipitation gage data is blended with precipitation estimates from a network of WSR-88D radars to produce cumulative precipitation maps. This processed data is one of the main inputs into the RFC's hydrologic model.

In the past, river forecasts were made strictly on the basis of rainfall which had occurred. Today, river forecasts incorporate quantitative precipitation forecasts (QPF) into the hydrologic model, as well. This has led to more accurate river forecasts, especially in the fall and winter months, when areal rainfall tends to be more uniform.
