Access the Southern California Weather and Hazards Data Viewer.* About the DataThe tool has been developed as a geographic information system (GIS) Internet map server application—to ensure data and analyses sharing capabilities with other decision makers. The forecast weather information is provided by the National Oceanic and Atmospheric Administration (NOAA) National Weather Service National Digital Forecast Database (NDFD) and is updated four times daily, 0015, 0615, 1215, and 1815 UTC. The NDFD provides forecast information from NOAA weather forecast offices for any location through a series of forecast grids detailing sensible weather elements (e.g., wind speed, temperature, etc.). A unique component of this tool is the sharing of NDFD data layers through an existing external Internet map service, which is provided by NOAA’s nowCOAST (nowcoast.noaa.gov). NowCOAST is a GIS web mapping portal to real-time coastal information developed by the NOAA National Ocean Service's Coast Survey Development Lab. The hazards planning data and base data were provided by the California Office of Emergency Services (OES) Southern Region and Southern California counties. ** Accessing NDFD DataThe NDFD data is being provided for this tool via an Environmental Systems Research Institute (ESRI) ArcIMS Image Service from nowcoast.noaa.gov. It can be brought into a desktop GIS by adding an ArcIMS Image Service in ESRI's ArcGIS and pointing it to nowcoast.noaa.gov. The service name at this address is "ndfd." Background InformationThe Southern California Weather and Hazards Data Viewer is an on-line mapping tool for the hazards community to monitor coastal storms and their associated hazards. The tool brings weather forecast information and hazards planning data into the same location—helping managers monitor coastal storms and visualize potential impacts. Having this information in one location helps users better and more efficiently understand the impacts of each coastal storm. The tool was developed through a partnership between the California Office of Emergency Services Southern Region, local offices of emergency services and planning in Southern California, and NOAA under the NOAA Coastal Storms Program (www.csc.noaa.gov/csp). The following NOAA offices participated in this project: the Coastal Services Center; the Los Angeles/Oxnard Weather Forecast Office; the San Diego Weather Forecast Office; and the Coast Survey Development Lab, which enhanced nowCOAST to provide NDFD forecast data for the tool. Enhancement of nowCOAST was aided by funding from the Coastal Storms Program.
