To issue these river forecasts, local 博体育 offices rely upon forecast guidance generated by a regional 博体育 River Forecast Center (RFC). The RFCs use complex hydrologic computer models to forecast rivers. 博体育 Tulsa is serviced by two RFCs, the co-located Arkansas-Red Basin River Forecast Center (ABRFC) and the Lower Mississippi River Forecast Center (LMRFC) in Slidell, Louisiana.

Most of the forecast points in the 博体育 Tulsa 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 博体育 offices receive these river stage forecasts from the RFCs and generate public products under several headings:

• an initial product warning interests that a river is forecast to rise above flood stage.
• a followup product which updates a River Flood Warning.
• a product which provides information when a river is forecast to reach Action Stage but expected to remain below Flood Stage.
• a product which provides information when a river is not forecast to reach Flood Stage.
• RRS feeds available
• Hydrology and Monthly Climate Summaries and Highlights

Precipitation data is vital to river forecasting. Local 博体育 offices must supply the RFCs with precipitation data to input into their computer models. The ABRFC and the LMRFC precipitation 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.
