The ability of the National Weather Service (NWS) to provide consistent weather hazard information is essential in building a weather-ready nation and delivering impact-based decision support services (IDSS).  The hazard builder is a multi-faceted vehicle that serves as a foundation to an end-to-end IDSS process in support of a forecaster decision support environment (FDSE). The hazard builder creates a database of graphical weather hazard risks utilizing a common platform and procedures found within the Advanced Weather Interactive Processing System graphical forecast editor. This database of graphical hazard risks is derived from weather elements which populate the National Digital Forecast Database and also utilizes output and guidance from national centers.

Weather hazard risks generated by the hazard builder are then integrated into the forecast process, operational decision-making, and interpretive decision support services. Internal to the NWS, the hazard builder supports the FDSE by identifying targets of opportunity, aiding forecaster decisions, promoting consistency of services, supporting operational tempo, and creating a common operating picture. External to the NWS, hazard builder output supports preparedness and response efforts prior to and during hazardous weather events by providing graphics that depict risk areas, risk levels, and potential impacts for numerous weather hazards. These graphics then provide a foundation for an array of IDSS for an increasingly diverse customer base. 

This presentation will provide a summary of hazard builder functionality and its role in supporting the IDSS process from science to services. Integration of hazard builder into the NWS Central Region forecast builder will also briefly be discussed.
