Overview and Status of the Hydrologic Forecast System in the National Weather Service Weather Forecast Offices
In 1996, the National Weather Service (NWS) delivered the first set of the Advanced Weather Interactive Processing System (AWIPS) to a limited number of NWS field offices. The software provided with this limited-function release included the Weather Forecast Office (WFO) Hydrologic Forecast System (WHFS), which performs a variety of operations in support of the Hydrology program at WFOs. Since that time, AWIPS has been deployed at all the NWS WFOs and the WHFS functionality has grown dramatically, with new functionality continually being added with each new release. The software and its associated relational database has grown to address operations outside the traditional domain of the WFO Hydrology program, and now shares the same database structure and provides support for selected operations at the RFCs. The WHFS now encompasses the full range of hydrologic activities, from ingesting, decoding, and posting data, to performing quality control and event monitoring of the data, to providing tabular and graphical data visualization tools, to basic hydrologic modeling capabilities, to generating and issuing products for a wide range of user needs. With the national implementation and accepted use of the WHFS, the need for field support led to the establishment of a dedicated operational support team. The support team, the development team, and a requirements and management team all work together to support the demands of this mission-critical system and to provide for its future growth. This paper will describe the current status of the WHFS, both in terms of field implementation and support operations, current development activities, and planned development activities.
