| [New] Experimental Tropical Cyclone Hazards Graphics | The Tropical Cyclone Hazards Graphics is an experimental, internet-based, product suite consisting of four hazard graphics: wind, tornado, coastal flood, and inland flood. These WFO-generated graphics provide qualitative forecasts for the primary tropical cyclone hazards based on the track, intensity, and uncertainties in the official forecasts from the National Hurricane Center (NHC), Storm Prediction Center, and Hydrometeorological Prediction Center. In a new era marked by digital and probabilistic forecasts, the hazards graphics provide users with local products tailored by the wide-ranging knowledge and experience of the local WFO for their area of responsibility.
18 WFOs participated in 2008 and 22 will participate in 2009. New AWIPS data, enhanced Smart Tools, and an improved web page highlight the enhancements for 2009 | TCHazardsGraphicexp2009.pdf |
| [New] Experimental Tropical Cyclone Surface Wind Speed Probabilities (TCSWSP) for the North Pacific Ocean in the National Digital Forecast Database (NDFD) | 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. | PDD_EXP_NDFD_TCWindSpeedProbPac2009.pdf |
| [New] Experimental Tropical Cyclone Wind Field Graphic Central Pacific | This experimental 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 | EXPTCWFG2009.pdf |
| [New] EXPERIMENTAL Web-based TRACON Briefings (Southern Region) | 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. | SR_CWSU_TRACON_Web_Briefing_PDD.pdf |
| [New] Experimental Western Region Graphical Weather Story of the Day | Graphical “Weather Story of the Day” is a graphical representation (product) which depicts the most important weather feature in the forecast area of responsibility of individual NWS Weather Forecast Offices (WFO). The “Weather Story of the Day” is not time dependent. That is, the product depicts the most significant weather feature through the 7-day forecast period. A graphical user interface allows the forecaster to include a brief text, a few sentences in length, describing the “Weather Story of the Day” graphical product. If necessary the product may include a series of images to more clearly communicate complex weather situations. Availability of this product is event driven. | GraphicalWXStoryPDD.pdf |
| [New] EXPERIMENTAL: National Ceiling and Visibility (NCV) Analysis Project | The NCV product is a frequently updated representation of current ceiling and visibility conditions derived from METAR (ASOS) stations and GOES satellite information.
The product's ceiling and visibility fields are derived through nearest-neighbor interpolation of METAR data. This interpolation process, in effect, 'stretches' limited-area METAR observations across the broader domain between stations while an accompanying process accounts for terrain effects on ceiling height. The resulting field helps to visualize the 'likely' conditions at range from METARS. | NCVAPDD2.pdf |
| [New] Experimental: Miami Tracon Approach and Departure Gates Forecast | The Experimental Miami Tracon Approach and Departure Gates Forecast (formerly called Experimental Miami Approach and Departure Gates Forecast)will complement the Collaborative Convection Forecast (CCFP) product by providing greater detail of convective occurrence and coverage when radar reflectivities are equal to or greater than 40dbZ and tops equal to or greater than FL200. This graphic forecast product is a modification of the Tracon and Gate Forecast product used at the ZTL CWSU. | SR_CWSU_TRACON_Gates_PDD.pdf |
| [New] EXPERIMENTAL: NWS Warning Alert Messaging Services via Mobile Device Technologies | The NWS is responsible for providing weather warnings and alerts in a timely and effective manner to support the protection of life and property. The NWS must provide this information to an increasingly mobile public who are using rapidly evolving technologies for accessing Internet content via mobile wireless devices. In response to this the NWS is developing weather warning services that take advantage of mobile device technologies such as Personal Digital Assistants (PDA) and cell phones, in order to better serve the public. The experimental application has been named Interactive NWS (iNWS).
The NWS Western Region is developing an application that will provide real-time, warning services tailored to the unique characteristics of cellular phones and mobile devices. This application will allow access to NWS watches, warnings, advisories, weather statements, forecasts and observations, as well as the ability to view looping RADAR imagery for the United States. Customers can also choose to automatically receive weather warning alerts as they occur for locations of interest via text messaging. This application will provide multiple levels of service to give customers options for accessing this information in a format that best fits the capability of their mobile devices.
The full-featured service envisioned by this application will be a mobile Internet-based graphical tool for viewing watches, warnings and relevant weather data, and for receiving real-time weather alerts for customer selectable locations on Internet-enabled cell phones. Background maps and layers of weather data are displayed as the customer moves the cursor around the map to locations of interest. When the customer is interested in receiving weather alerts for a given location, they select that location and the type(s) of alert, such as tornado warnings, or winter storm warnings, and this information is saved to a database at WRH. Several locations can be saved for each customer’s profile. When a warning comes into effect for any of the customer selected locations, a text message warning is automatically sent to the customer via their cell phone number.
