Product Name Brief Description Operational Date
NWS Watches, Warnings, and Advisories using ATOM and CAP XML based Formats Internet based feeds of NWS watch/warning/advisory products using the SML-based Common Alerting Protocol (CAP) v1.1 and ATOM message formats. CAP is an information standard used to facilitate emergency information sharing and data exchange across local, state, tribal, national and non-governmental organizations of different professions that provide emergency response and management services. The ATOM feed provides an index of active NWS CAP messages in a geographic area. The CAP and ATOM feeds allow NWS Partners, emergency managers and others to access, re-use and re-distribute this mission critical information to a greater extent than ever before possible. For example, CAP messages may be readily integrated with consumer electronics decision support systems and mobile alerts. 2011-03-15 
HPC Today's National Weather Chart in Spanish This product is a Spanish language version of the HPC National Forecast Chart providing an overview of todayís national weather with an emphasis on hazardous and significant weather 2011-03-01 
HPC Probabilistic Freezing Temperature Charts This product provides a probability that the temperature at a location will fall below 32 degrees Fahrenheit. This product is derived from the NDFD temperature grid data and the 2 meter temperature grid spread data from the GFS ensemble. 2011-03-01 
Mountain Recreational Point Forecasts The Mountain Recreational Point Forecasts complements the official narrative text recreational forecasts that have long been issued by WFO Burlington, and in similar forms by other WFOs across the country. The web based display leverages the Google Maps interface to allow the user to readily access the specific mountain peak forecasts available. The WFO Burlington Mountain Recreational Forecast program serve a public safety purpose by providing weather forecasts for the highest elevations across the region, which are frequently impacted by severe and life-threatening weather that is not experienced at the lower elevations 2011-01-06 
Enhanced Product addition of Max Wind-Hail Size Coding Tag for Severe Thunderstorm Warnings and associated follow up sta The Central Region Severe Thunderstorm Warning (CR SVR) is an alphanumeric product providing short-fused warning in¨formation on hazardous conditions associated with thunderstorms which are expected to pose a threat to life and/or real property. This product is prepared by each National Weather Service (NWS) Weather Forecast Office (WFO) for their County Warning Area (CWA) of responsibility. Integrated Warning Team workshops, as well as several societal impacts groups, have indicated a desire by many emergency managers for a concise tag line on the end of the SVR product identifying maximum hail size and wind speeds expected for a given SVR warning. Local area sirens are typically alarmed for tornadoes only. Decoding this tag line will facilitate the capability for local area EMs to trigger sirens for particularly dangerous severe thunderstorm events when conditions exceed locally developed thresholds for thunderstorm induced wind and or hail size. 2010-11-15 
Gridded Significant Wave Heights from the National Centers The traditional format for the significant wave height products from the National Centers are graphical depictions of the observed and forecast wind-driven waves for the Atlantic and Pacific Oceans adjacent to the coasts of the Continental United States (US) and extending south over the Caribbean Sea and the west coast of Central America. These graphical products have been prepared for many years in the raster format by the Ocean Prediction Center (OPC) and the National Hurricane Centerís (NHC) Tropical Analysis and Forecast Branch (TAFB) and transmitted via radiofax and the internet. The production and dissemination of the traditional raster format for the graphical significant wave height products from the OPC and TAFB will continue. The gridded products are prepared for the initial wave heights and the 24 hour and 48 hour forecast wave heights in Gridded Binary (GRIB2) format. The gridded products are disseminated by the National Weather Service (NWS) Telecommunications Gateway to the Weather Forecast Offices (WFOs), National Centers, and other users. Users may also access these products via the internet at: 2010-10-24 
NWS Pendleton Decision Support Web Page The Decision Support Web Page provides the following information to Internet users: 1) Graphical weather hazards for the next seven days using a Google Map interface; 2) Graphical ventilation forecast for the next 3 days; 3) Daily dispersion outlook text forecast; 4) Links to the SPC Fire Weather Forecast; 5) Links to aviation tactical decision aids; 6) Links to the SPC Day1 and Day2 Convective Outlooks; 7) Uncertainty forecasts for temperature using plume diagrams for 12 MOS points in the Pendleton County Warning Area; 8) Links to GOES satellite and NEXRAD radar data; 9) Current observations displayed using Google Maps; 10) Text Hazardous Weather Outlook, Area Forecast Discussion, Local Storm Report, and Short Term Forecast products; 2010-08-16 
Hourly Multi-Sensor Precipitation Estimate Web-Based Service The National Weather Service (NWS) collects rainfall data to support its forecast and warning operations. Individual River Forecast Centers (RFCs) and Weather Forecast Offices (WFOs) typically provide rainfall collectives in text and graphical formats for their areas of responsibility. This service provides unified hourly precipitation estimates for the Continental US and the Commonwealth of Puerto Rico on the Internet. The service includes graphics that display these precipitation data, as well as the ability to download the information in shapefile format for seven days post-event. This suite of graphics includes precipitation estimates for the last 1, 3, 6, 12, 24, 48, and 72 hourly accumulations, as well as "since 12z" accumulations. Hourly archives will be maintained. 2010-07-20 
SR CWSU Web-based TRACON Briefings The National Weather Service-Southern Region Center Weather Service Units (CWSU) may develop web-based briefings for Terminal Radar Approach CONtrol (TRACON) that aviation customers can use for tactical and strategic planning for operations. Maps and other graphics used in the web-based TRACON briefings are culled from various maps, models and charts available on the web. Variations in the presentation and depiction are authorized based on the needs and requirements of the specific ARTCC TMU and TRACON. 2010-06-15 
Southern Region TRACON APPROACH and DEPARTURE GATE FORECAST PRODUCT The Southern Region Tracon Approach and Departure Gate Forecast will complement the Collaborative Convection Forecast Product (CCFP) by providing greater detail of convective occurrence and coverage of significant reflectivities and echo tops as determined collaboratively between the CWSU MIC, the Air Route Traffic Control Centerís (ARTCC) Traffic Management Unit (TMU) and the impacted Terminal Radar Approach Control (TRACON). Variations in the presentation and depiction are authorized based on the needs and requirements of the specific ARTCC TMU and TRACON 2010-06-15 
Tropical Cyclone Surface Wind Speed Probabilities (TCSWSP) for the North Pacific Ocean in the NDFD This update makes the TCSWSP in the NDFD for the North Pacific Ocean operational for the 2010 hurricane season. The TCSWSP elements depict probabilities, in percent, of sustained surface wind speeds. These probabilities are provided for wind speed thresholds equal to or exceeding 34-, 50-, and 64-knots. These wind speed probabilities are based on the track, intensity, and storm structure (size in terms of wind radii) uncertainties in the official tropical cyclone forecasts. TCSWSP elements covering the North Pacific Ocean are available in NDFD in experimental status. Similar elements for the continental U.S. are available in NDFD in operational status. 2010-05-13 
Instant Messaging for NWS and Partners :NWSChat Instant Messaging (IM) is a real-time, Internet-based method of electronic communication between two or more parties. IM may also be referred to as "chat". Utilizing a software application known as a "chat client", multiple users can compose and send messages to each other in forums known as "chat rooms." In addition to manually composed mesages, chat sessions may contain various automated software-generated messages that convey information about disseminated National Weather Service (NWS) products. NWSChat is the name for the system providing IM capability to the NWS. NWSChat consists of hardware and software maintained by NWS and client software that can be accessed via a web browser or downloaded on the users computer. 2010-03-30
