Product Name Brief Description Operational Date
National Digital Forecast Database (NDFD) Graphic Forecast Displays The National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) National Digital Forecast Database (NDFD) Graphic Forecast Displays ( are web-based presentations of digital forecast data originating from local Weather Forecast Office (WFO) digital databases and the NDFD server. The data are displayed in a mosaic form on national and regional scales. Local scale products are not covered under this Product Description Document (PDD). For more information on the NDFD, please refer to the NDFD Information web site at the following URL: 2008-07-08 
National Digital Forecast Database (NDFD) Gridded Data Under statute, the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) is charged to collect data on climate, water, and weather, provide forecasts and warnings of severe weather in order to protect life and property, and create and disseminate forecasts and other weather information for the benefit of a wide range of weather sensitive businesses and activities. By capitalizing on rapid advances in science and technology and infusing these advances into its operations, the NWS has taken steps to proactively respond to ever changing and growing demands of its customers and partners. The 2003 Fair Weather report, produced by the National Research Council, recommended making NWS data and products available in an Internet accessible digital form. The specific recommendation is as follows: ?Information held in digital databases should be based on widely recognized standards, formats, and metadata descriptions to ensure that data from different observing platforms, databases, and models can be integrated and used by all interested parties in the weather and climate enterprise.? The Internet is now a principal means of communicating NWS forecasts. 2008-07-08 
NDFD Quantitative Precipitation Forecast (QPF) for Hawaii On July 8, 2008 the Quantitative Precipitation Forecast (QPF) for Hawaii to the National Digital Forecast Database (NDFD) was transitioned to operationa Status. On November 1, 2006, the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) introduced Quantitative Precipitation Forecast (QPF) for Hawaii to the National Digital Forecast Database (NDFD) as an experimental element. QPF is already available in NDFD on an experimental basis for the conterminous U.S. (CONUS), the 16 pre-defined NDFD CONUS subsectors, Puerto Rico, and the U.S. Virgin Islands. 2008-07-08 
Western Region Fire Weather/Marine Point Forecast Matrix (PFM) Land management agencies have expressed a need for easily accessible tabular forecast data that is tailored toward fire behavior applications. A fire weather version of the Point Forecast Matrix (PFM) table fits this need well because it allows agency specialists to quickly run simple fire behavior models for planning purposes. This is turn allows land management agencies to ensure the safety of fire crews as well as better plan prescribed burns and other projects in a cost and resource effective manner. 2008-06-09 
Graphical Milepost Forecast The Graphical Milepost Forecast allows the user to check the forecast in either meteogram or table format for the next 24 hours at mileposts along all major highways across the Pendleton CWA. 2008-05-19 
Hurricane/Typhoon Local Statement (HLS) Starting with the 2015 hurricane season, Southern and Eastern Region WFOs having HLS responsibility will issue the HLS as a non-segmented product with no VTEC for land areas only. A new WFO product, “Hurricane Local Watch/Warning Product”, is now being used to issue tropical cyclone watches and warnings for land areas. The Marine Weather Warning (MWW) product is being used for tropical cyclone watches and warnings for marine zones in a WFOs county warning area. There will not be any change in the format to the HLS for Western and Pacific Region offices which issue the product for the 2015 Hurricane Season, except tropical cyclone watches/warnings for marine zones would be moved to the MWW. Plans for expanding the revamped HLS to Western and Pacific Region offices are being developed with implementation TBD.The HLS is an alphanumeric product alerting the public of present and anticipated local tropical cyclone affects. Coastal and selected inland Weather Forecast Offices issue HLSs when their County Warning Area and adjacent coastal waters is affected by a tropical cyclone watch/warning or evacuation orders. 2008-04-29 
Maximum Tropical Cyclone Wind Speed Probability Table The WSP shows the probability that maximum 1-minute wind speed forecast for the tropical cyclone will be within one of seven intensity ranges/storm classifications through 72 hours. The maximum 1-minute wind speed forecasts correspond to the wind speed forecasts in the Tropical Cyclone Forecast/Advisories (TCM) product. The probabilities are based on National Hurricane Center (NHC) forecasts from 1988-1997. NHC issues this experimental product for tropical cyclones in the Atlantic and Eastern Pacific basins. This experimental product is also issued for subtropical storms. 2008-04-17 
Tropical Cyclone Storm Surge Probabilities The product consists of a graphic and GRIB2 data for creating the graphic for the Gulf of Mexico and Atlantic coastal areas of the continental United States. The graphic shows probabilities, in percent, of storm surge exceeding 2 feet through 25 feet, at 1 foot intervals (e.g., the probabilities in percent, of storm surge exceeding 2 feet, 3 feet, 4 feet, …, 25 feet). This storm surge graphic is based upon an ensemble of Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model runs using the National Hurricane Center (NHC) official advisory and accounts for track, size, and intensity errors based on historical errors. 2008-04-15 
Graphical Short Term Forecast Product GraphiCast The Graphical Short Term Forecast Product (GraphiCast) is a graphical representation of the short term weather forecast (0 to 6 hours) in the forecast area of responsibility of individual NWS Weather Forecast Offices (WFO). It depicts current radar, satellite, or observation imagery with graphical and text annotations showing forecast weather conditions in the next several hours. In rapidly developing situations, it is updated at least hourly. 2008-03-10 
Tactical Convective Hazard Product (TCHP) The TCHP provides a graphical presentation of thunderstorm hazards to aviation operations. It depicts current hazardous thunderstorms and a one-hour forecast of hazardous thunderstorm locations. The TCHP updates automatically every 5 minutes. The product is created from radar and lightning data as well as human-generated Convective SIGMET in-flight advisories (SIGMETs updated hourly). 2008-03-10 
CEILING HEIGHT AND SURFACE VISIBILITY INFORMATION ON THE MULTI-FORMAT FORECAST INFORMATION WEB PAGE Advances in computer capabilities and web services technologies, as well as scientific advances in National Weather Service (NWS) software, have afforded an opportunity for the NWS to create ceiling height and surface visibility customer-based products and services. Information dissemination via the world wide web (www) allows customers to obtain higher resolution ceiling height and surface visibility information in a variety of formats on demand. 2008-03-10 
Probabilistic Quantitative Precipitation Forecasts NOAA's Strategic Plan states that we are to "Improve the reliability, lead-time, and effectiveness of weather and water information and services that predict changes in environmental conditions." To support that effort, The National Weather Service Strategic Plan for 2005 to 2010: Working Together to Save Lives, establishes a mission goal to develop new capabilities and move into a new direction of forecasts... and expand beyond traditional weather and water products. In response to the NOAA and NWS goals, the Weather Forecast Office in Tulsa, Oklahoma (TSA) has developed a method to provide probabilistic quantitative precipitation forecasts on a routine basis, in the form of probability of exceedance (POE) forecasts. This method will be used at several Weather Service Forecast Offices (WFOs) in the Southern Region. These POEs will provide our clients and customers with more detailed precipitation forecasts that they can use in their decision-making processes. 2008-03-10
