Product Name Brief Description Operational Date
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 
Crosswind Calculator Aid The Crosswind Decision Aid is color-coded according to the degree of impact the wind will have on various runways green indicating little or no impact; yellow indicating marginal impact; and red indicating significant impact. Each color level is triggered based on a user-defined wind direction and wind speed threshold. The product also includes a Wet Runway/IFR factor that effectively lowers the crosswind speed thresholds. 2008-03-05 
HotSeat Warning Simulator HotSeat is a web-based warning simulation tool. It uses archived WSR-88D data from actual events along with severe weather reports and damage survey photographs in a displaced real-time (DRT) mode to approximate the feel of issuing severe weather warnings in the National Weather Service. Upon completion of each event, the participant receives a score indicating his/her success in the simulation. 2008-03-05 
NDFD CLIMATE NDFD Climate is a computer application that creates images of forecast and climatological parameters for the continental U.S. from two different digital data sets. The first data set is the NDFD (National Digital Forecast Database) weather forecast grids produced by the NOAA National Weather Service (NWS) and the second data set is PRISM (Parameter-elevation Regressions on Independent Slopes Model), an expert system that uses point climatological temperature data and a digital elevation model (DEM) to generate gridded estimates of climate parameters. The NOAA National Weather Service (NWS) National Digital Forecast Database (NDFD) contains digital forecast grids of sensible weather elements such as temperature, wind, and precipitation in a mosaic from collaborating field offices across the U.S. for forecasts out to seven days. Daily digital climatology grids of maximum and minimum temperature are created using Parameter-elevation Regressions on Independent Slopes Model (PRISM; Daly et al. 1994) method. NDFDClimate grids produced include: PRISM derived normal daily maximum and minimum temperatures, NDFD derived forecasted heating and cooling degree days through day 6, NDFD forecasted daily minimum and maximum temperature anomalies derived from PRISM daily climate fields through day six, NDFD derived five day total of forecast heating and cooling degree days, NDFD 60 hour total of liquid equivalent QPF, NDFD forecasted number of hours the temperature is above or below a defined temperature through day three, NDFD forecasted 24- and 48-hour forecast temperature changes from forecast issue time. 2008-02-21 
National Digital Forecast Database Extensible Markup Language National Digital Forecast Database (NDFD) Extensible Markup Language (XML) is a service providing the public, government agencies, and commercial enterprises with user selected components for point locations of the National Weather Service?s (NWS) data embedded in XML elements. NDFD XML provides users the ability, using a machine-to-machine paradigm, to retrieve the XML-wrapped data via the Internet. This web service is provided using the SOAP protocol.... 2008-02-11
