DELETED Product Name Brief Description Submitter Status
Experimental Potential Storm Surge Flooding Map The Potential Storm Surge Flooding Map is an experimental product that provides valuable information on potential storm surge flooding for areas along the U.S. Gulf and East Coast at risk from storm surge during a tropical cyclone event John F. Kuhn Evaluation Period Ended
Experimental RFC Decision Support Interface A Google Earth based mapping service in which a variety of existing RFC products would be available for display and overlay.The NWS West Gulf RFC and Arkansas Rred Basin RGC are testing a new Hydrologic Decision Support Map Service that melds a variety of spatial data products on the same background map to aid analysis and decision making. The interface provides stakeholders and the flexibility to create customized maps and the ability to scale maps beyond a single RFC boundary. Tracy Clark Approved to Discontinue
Experimental Southern Region Mapping API Widget/Smartphone Web Page A standardized way in which any office could easily embed a highly-customizable Google Maps interface and menu system into any web page. Melinda Bailey Approved to Discontinue
Experimental Spanish Language Hurricane Local Statement WFO Brownsville has developed a text formatter that generates a Hurricane Local Statement (HLS) using Spanish language, in a manner identical to the process that creates the English language HLS. This product is designed to convey critical warning information in tropical cyclone events to a significantly large population in the Brownsville CWA that speaks English as a second language, or not at all. By generating an HLS in Spanish, rather than translating an English-language product into Spanish, saves critical time in dissemination and avoids a heavy workload on the limited number of Spanish speaking staff at WFO Brownsville.

Experimental Wind Speed Probabilities-based Tropical Cyclone Danger Graphic The Tropical Analysis and Forecast Branch (TAFB) is providing on an experimental basis a Tropical Cyclone Danger Area graphic based on the 34-kt wind speed probabilities through 72-hours from the latest tropical cyclone advisory for an active tropical cyclone. The graphic outlines avoidance areas using the 10% and 50% 34-kt wind speed probability contours from the latest tropical cyclone advisory issuances for both the Atlantic and East Pacific basins (Figures 1 and 2). The current Tropical Cyclone Danger Area graphic utilizes the mariners 1-2-3 rule to outline avoidance areas through 72 hours for active tropical cyclones. Feedback from users indicated that the use of the 1-2-3 methodology has led to “over-warned” large avoidance areas. The 1-2-3 methodology assumes an average forecast track error of 100 nmi at Day 1, 200 nmi at Day 2 and 300 nmi at Day 3 rule (Figure 3). These values are well above the most recent 10-year averaged forecast track errors of 50 nmi at Day 1, 85 nmi at Day 2 and 120 nmi at Day 3. Hugh Cobb Approved for Operational
Forecast of Reference Crop Evapotranspiration (FRET) for Short Canopy Vegetation FRET is the expected depth of water (in hundredths of inches) that would evaporate and transpire from a reference crop under the forecast weather conditions on a daily and weekly basis over the next 7 days. The FRET is for short crops with an approximate height of 12 cm similar to full cover grasses. Daily FRET grids for the next 7 days, total FRET grids for the 7-day period, FRET departure from normal grids, and climatology grids for reference evapotranspiration are available via a web page interface for the nation via the NDFD.An ETT text product composed of a supplemental table generated from the gridded data is available at: http://www.nws.noaa.gov/view/validProds.php?prod=ETT Dan Matusiewicz Approved for Operational
Proposed changes to the criteria for issuing tropical cyclone watches and warnings to include certain land-threatening disturbances that are not yet tropical cyclones The National Weather Service (NWS) proposes beginning on or about May 15, 2017,to have the option to issue watches, warnings, and graphical and textual advisory products for disturbances that are not yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 48 hours. Under previous long standing NWS policy, the NWS has not been permitted to issue a hurricane or tropical storm watch or warning until after a tropical cyclone had formed. Jessica Schauer Approved for Operational
Proposed Changes to Tropical Cyclone Forecast Graphics and GIS Files Effective on or about May 15, 2017, the appearance of the graphics accompanying tropical cyclone advisory packages issued by the National Hurricane Center (NHC) and Central Pacific Hurricane Center (CPHC) will change. These changes are required for the NHC and CPHC to begin issuing forecasts and watches/warnings for potential tropical cyclones.three new Keyhole Markup Language (KML) files will be available and the wind speed probability Geographic Information System (GIS) files will be available at higher resolution. Wayne Presnell Approved for Operational
Proposed Expansion of PR Marine Forecast Matrix to National Scope The National Weather Service (NWS) Marine Forecast Matrix (MFM) provides a tabular forecast of wind direction and speed, swell direction and height, wind wave height, significant wave height, cloud cover, probability of precipitation, and areal precipitation coverage.
