Location of River Forecasting Centers <br />Boundary of Area Served by <br />River Forecast Centers <br />8 Including Water Supply Forecast Service <br /> <br />Figure 8. - Locations of NWS River Forecast Centers. <br /> <br />primary importance for hydrologic forecasting are precipitation and river stage data, received <br />on a timely basis. The snowpack water content, ambient temperature, and the soil moisture <br />antecedent index are also vital to generating a river forecast. Other types of data required <br />to fully comprehend a hydrologic situation and make hydrologic forecasts include reservoir <br />data (inflow, release changes, and pool elevations), radar reflectivity observations, upper-air <br />atmospheric soundings, satellite observations, and NMC prognostic model output. <br /> <br />· Recommendation - Reclamation should ensure that all of its reservoir and early warning <br />systems data needed for hydrologic forecasting are received at the responsible NWS RFC <br />and WFO (Weather Forecast Office) on a timely basis. <br /> <br />New technologies and advances in remote sensing, high-speed computers, and <br />telecommunications will be used in the MAR (modernization and associated restructuring) <br />of the NWS to improve service to the public. One significant change is the installation of a <br />NEXRAD (next generation radar) WSR-88D network. These changes will result in the NWS's <br />ability to collect and process large amounts of hydro meteorological data at much faster rates, <br />which provides the potential for more accurate, timely, and site-specific forecasts and <br />warnings. See Friday (1994) for an overview of the NWS MAR. <br /> <br />· Recommendation -Reclamation should work cooperatively with the NWS on developing <br />techniques to apply (NEXRAD) WSR-88D radar data and products to our operational <br />water management decisions. <br /> <br />21 <br />
