Hazard Grids in the National Digital Forecast Database The NWS provides access to operational and experimental gridded forecasts of weather elements (e.g., maximum temperature, sky cover)through the NDFD. The NDFD contains a seamless mosaic of digital forecasts from NWS field offices working in collaboration with the National Centers for Environmental Prediction (NCEP). The hazard grids are prepared by all Weather Forecast Offices (WFO) and are available via the NDFD. Hazard grids are valid for more than two hours. The hazard grids depict all active long duration watch, warning and advisory hazards issued by NWS WFOs . The hazard grids include long duration coastal, marine, nonprecipitation, tropical and winter weather hazards. It also includes convective and some hydrological watches. It does not include the following short duration warnings: Tornado Warning, Severe Thunderstorm Warning, Extreme Wind Warning, Flash Flood Warning, and Special Marine Warning. It does not include the following Long Duration Watches and Warnings issued in RiverPro and WarnGen:Flood Watch for forecast points, Areal Flood Warnings and Flood Warnings for forecast points. In addition, it initially will not include Gale Warnings, Storm Warnings and Hurricane Force Wind Warnings issued in the Offshore and High Seas forecast by OPC and TAFB. The NDFD Hazard grid definition is defined as,a weather or hydrologic hazardous event issued for the protection of life and property and the enhancement of the national economy. The Hazards grid will be in experimental status in the NWS Alaska Region until further notice. 2009-09-15 
National Digital Forecast Database User Defined GRIB2 files Gridded forecasts requested by a user from the National Digital Forecast Database (NDFD) are encoded into GRIB2 and transmitted to that user via the World Wide Web (WWW). A user can be any member of the public, a government agency, or a commercial enterprise. The user chooses one of the weather elements that is available in the NDFD and specifies the bounding latitudes and longitudes of the grid that will be transmitted via a Web CGI interface. GRIB2 is data encoding standard described by the World Meteorological Organization in its document FM92 GRIB, Edition 2, Code Form and Tables.... 2009-07-01 
NWS web services via wireless technologies NWS is responsible to make its weather, water and climate information widely available to taxpayers using commonly accepted standards and technologies.One of the most widely accepted, available and cost effective means of accomplishing this objective is the use of web services via the internet, and NWS has implemented a corporate-wide HTTP-based web service. This service has allowed users instant access to current NWS information via industry standard web browsers and internet connections. A rapidly evolving technology in the United States today is the ability to access internet content via wireless devices such as Personal Digital Assistants (PDA) and cell phones. 2009-07-01 
Fire Weather Point Forecast Matrix Land management agencies in Georgia and North Carolina 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. The product is called the Fire Weather Point Forecast Matrix (PFW) and is generated routinely for the National Fire Danger Rating System (NFDRS) sites or other areas as determined by the users. This additional data will help 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. Also, land managers have expressed a need for better tools to predict and manage smoke dispersion. They have also requested that the NWS include an Atmospheric Dispersion Index (ADI) and Low Visibility Occurrence Risk Index (LVORI) in the PFW product. WFO Fire Weather PFW’s are generated for the Remote Automated Weather Station (RAWS)/NFDRS sites using an edited version of the standard PFM formatter. This formatter produces needed fire weather parameters from the local WFO’s Digital Forecast Database (DFD). PFW's can be generated for any grid point in a DFD based upon user request. The web delivery of the product for fire weather customers will include a disclaimer at the top of the page stating “This product is for planning and review purposes only and is not to be substituted for an official fire weather spot forecast. The data displayed are calculated from a 5.0 by 5.0 km digital database and only approximates weather conditions in highly varying terrain. Please relay any comments you have to your local NWS office. An example of the PFW can be seen at: http://www.srh.noaa.gov/productview.php?pil=GSPPFWGSP . 2009-06-08 
Water Resource Outlook Multi-Media Briefing This Internet-based multi-media recorded briefing provides water managers in the Southeast U.S. with a one to three month water resource outlook based on current surface water/groundwater/soil conditions, reservoir conditions, input from state and federal water resource partners on supply and water use, Climate Prediction Center weekly/monthly temperature and precipitation forecasts, and SERFC ensemble streamflow predictions. 2009-06-03 
Observed Precipitation Map The National Weather Service (NWS) collects rainfall data to support its forecast and warning operations. Individual River Forecast Centers (RFCs)and Weather Forecast Offices typically provide rainfall collectives in text format and graphical format for their areas of responsibility. The National Centers for Environmental Prediction (NCEP) Climate Prediction Center (CPC), collects additional data from cooperative observers. This rainfall data is made available to HPC and is used extensively for verification purposes.This rainfall data is plotted on a map of the CONUS and made available to forecasters. The data is used for feedback on forecast accuracy and can be used in case studies and other scientific endeavors. 2009-06-01 
Weekend Weather Graphic Web site statistics have shown that traffic on WFO websites increases as the weekend approaches. Customers are looking for the forecast for the upcoming weekend so that they can plan their activities. The Weekend Weather Graphic provides a quick and easily accessible view of the forecast for the weekend. The Weekend Weather Graphic is comprised of maximum temperature (MaxT),minimum temperature(MinT), and probability of precipitation (PoP) derived from the NDFD grids for the WFO forecast area. 2009-05-19 
Lightning Potential Index The Lightning Potential Index (LPI) is a web graphic that displays an index of lightning potential for various parts of the day, with a second day for planning purposes. This product will be issued routinely in the morning and updated as necessary. 2009-05-19 
Graphical Tropical Weather Outlook This document describes the Graphical Tropical Weather Outlook (TWO) produced by the National Hurricane Center (NHC) for the Atlantic and Eastern Pacific Hurricane basins and by the Central Pacific Hurricane Center (CPHC) for the Central Pacific Hurricane basin. This product is a visual companion product to the text TWO. The following changes have been made for effective May 15 for NHC Products and June 1 for CPHC Products: NHC:1. The current location of all active tropical cyclones will be included on the 5-day GTWO. 2. The current location of potential tropical cyclones will be included on the 2-day and 5-day GTWO. 3. The current location of the potential tropical cyclones will be depicted by an x, with the number of the potential cyclone (e.g., One) displayed above the x. The x will be color coded based on the forecast likelihood of tropical cyclone formation during the 2- or 5-day period corresponding to that graphic: - Yellow, 30 percent or less chance - Orange, 40-60 percent chance - Red, 70 percent or greater chance A swath showing the forecast development area of the potential tropical cyclone will not be shown on the 5-day GTWO to avoid confusion with the existing 5-day track forecasts that will be provided for those systems. 4. The current location of potential tropical cyclones will not be included in the shapefile that accompanies each issuance of the GTWO. Users will be directed to the shapefiles accompanying the full forecast advisory for potential tropical cyclones. The forecast advisory shapefiles will include the current location and forecast track of the potential tropical cyclone. CPHC:Beginning on or around June 1, 2017, the Central Pacific Hurricane Center (CPHC) will expand its 2-Day Tropical Weather Outlook (TWO) to 5 days. CPHC will also introduce a 5-Day Graphical Tropical Weather Outlook (GTWO) graphic in addition to 2-Day graphic already available. These changes will allow all NWS TWO and GTWO products to have the same valid times and formats. The 5-Day TWO from CPHC will provide a current assessment in plain language of areas of disturbed weather and their potential for tropical formation over the next 120 hours for the central Pacific basin. Like the 2-Day TWO, the new 5-Day TWO will provide probabilistic information, in 10-percent increments, about a system's potential for developing into a tropical cyclone. The forecast and discussion will be provided on a disturbance-by-disturbance basis for both the 2-day and 5-day periods for the central Pacific basin. 2009-05-15 
Tropical Cyclone Wind Field Graphic This update makes the Tropical Cyclone Wind Field Graphic (TCWFG) issued by the Central Pacific Hurricane Center operational for the 2010 hurricane season. This graphic illustrates the areas potentially being affected by tropical cyclone sustained winds of varying force. The graphic also shows an approximate representation of coastal areas under a hurricane warning, hurricane watch, tropical storm warning and tropical storm watch. The white dot indicates the current position of the center of the tropical cyclone, and the dashed black line shows the history of the center of the tropical cyclone. 2009-05-15 
National Digital Forecast Database (NDFD) Convective Outlook Hazard Probability Elements As of April 30, 2009, the following Convective Outlook Hazard Probability elements prepared by the SPC are now available in the NDFD in operational status Categorical Convective Outlook for today (Day 1), tomorrow (Day 2), and the day following (Day 3) Probability of Tornadoes (Day 1) Probability of Hail (Day 1) Probability of Damaging Thunderstorm Winds (Day 1) Probability of Extreme Tornadoes (Day 1) Probability of Extreme Hail (Day 1) Probability of Extreme Thunderstorm Winds (Day 1) Total Probability of Severe Thunderstorms (Day 2 and Day 3) Total Probability of Extreme Severe Thunderstorms (Day 2 and Day 3) All of these elements are currently only available for the contiguous U.S. (CONUS) and the 16 pre-defined NDFD CONUS subsectors. The Convective Outlook Probabilities are issued for a convective day from 12 UTC to 12 UTC. Day 1 Outlooks are valid from 12 UTC on Day 1 (or, if issued after 12 UTC from the issuance time) to 12 UTC on Day 2. The Day 2 products are valid from 12 UTC on Day 2 to 12 UTC on Day 3. The Day 3 products are valid from 12 UTC on Day 3 to 12 UTC on Day 4. The Categorical Convective Outlook elements specify the perceived level of threat via the descriptive wording Slight, Moderate, and High Risk. However, these outlooks, do not display the forecaster’s expectations of the individual severe weather hazards (large hail,damaging winds, and tornadoes) The individual probabilistic elements further express forecaster uncertainty of the individual severe weather hazards through the use of probabilities (i.e., percent likelihood of occurrence). In the Day 1 period, forecaster expectations of large hail, damaging winds, and tornadoes are explicitly conveyed in separate forecasts. By producing forecasts of each hazard individually, users who are sensitive to one particular threat (e.g., car dealers and large hail) can make more informed decisions. 2009-04-30
