This paper describes the design and ongoing development of the NDFD. In concert with the national deployment of the Interactive Forecast Preparation System (IFPS), digital forecasts are being sent to the NDFD central server and stored in a relational database. From these individual submissions, national mosaics are produced and updated.
The process by which forecast mosaics are transformed into NDFD products is illustrated. Products will be created on the NDFD central server and distributed via national and regional NWS web farms. Software used to create NDFD products and provide data access services is discussed. Future enhancements to the NDFD are presented.
