[Modification] Enhanced Product Experimental Fire Weather Planning Forecast (FWF) Bullet Format A Fire Weather Forecast (FWF) that utilizes left-justified asterisks to begin each line of text. The asterisks help maintain proper word wrapping and indentations in the AWIPS text editor. This significantly reduces the amount of time needed to edit the product before dissemination. FWF Text Format - NATIONAL draft PDD.pdf
[Modification] Enhanced Product Experimental RFW Bullet Format (National Optional)Fire weather customers in two NWS Regions have expressed current Fire Weather Warnings headlines result in long, complex RFW sentences that are difficult to understand. The Warning headlines must be read to fire fighters over the radio; so quick and efficient messaging is vital to user actions. To address these concerns, select Western (WFO BYZ) and Southern Region WFOs (WFOs servicing West Texas, the Oklahoma Panhandle and New Mexico) will provide an experimental RFW format for the 2013 fire season. The experimental product places the weather threat, reason for issuance and affected area from the main headline and into several, easy to read bullets immediately below the headline Enhanced RFW Bullet Format - National PDD_9_13.pdf

PDD updated in 2011 to extend comment period. PDD updated in 2010 to extend comment period and to update links. PDD updated in 2009 to include new elements: Hazards, Weather, Temperature, Dew Point, Wind Gust, Sky Cover, Apparent Temperature, Relative Humidity, Quantitative Precipitation Forecast (QPF) and Snow Amount. Under statute, the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) is charged to collect data on climate, water, and weather, provide forecasts and warnings of severe weather in order to protect life and property, and create and disseminate forecasts and other weather information for the benefit of a wide range of weather sensitive businesses and activities. By capitalizing on rapid advances in science and technology and infusing these advances into its operations, the NWS has taken steps to proactively respond to ever changing and growing demands of its users. The most recent experimental digital datasets (and associated graphic forecast displays) integrated into NDFD are the following elements for Alaska: Maximum Temperature, Minimum Temperature, 12-hour Probability of Precipitation, Wind Speed, Wind Direction, and Significant Wave Height.

[Modification] Experimental Aviation Impact Guidance for Convective Weather (AIGCW) The Aviation Impact Guidance for Convective Weather (AIGCW) is a graphical forecast capability that represents the probability of convective weather impacting air traffic operations in the National Airspace System (NAS). The weather portion of this product utilizes the Short Range Ensemble Forecast (SREF) Calibrated Thunderstorm output and the air traffic portion utilizes a 5-year sample set of historical air traffic data from 1 January 2004 through 31 December 2008. The AIGCW capability is then able to graphically illustrate the probability of convective weather impact to the normal albeit historical flow of air traffic in the NAS. The AIGCW was developed in conjunction with the FAAs longer range collaborative strategic planning process which is well beyond the traditional 6hr strategic planning timeframe. AIGCW provides a convective weather impact forecast to air traffic flows for 1-hour forecast intervals through 39 hours and 3-hour intervals through 87 hours. AIGCW_PDD.pdf
[Modification] Experimental Aviation Summer Weather DashboardThis is a website maintained by AWC with aviation weather information. It is intended for use by airline operators and FAA Traffic Managers for strategic coordination and planning.The Experimental Aviation Summer Weather Dashboard depicts the potential of convective weather impact to the Core 30 (minus Honolulu) airports and their associated standard terminal approaches. Updated four times per day, the web display shows the potential impact to each airspace through a matrix of color coded boxes that depict nominal (green), slight (yellow), moderate (orange), and high (red) likelihood of occurrence out through a day two forecast. The probabilistic information is calculated using the Short-Range Ensemble Forecast (SREF) numerical weather prediction system. PDD_sumrdash.pdf
[Modification] Experimental Beach Hazards StatementEnhancement to the Coasatal Hazards Message (CFW). The Marine and Coastal Weather Services program has identified a need to address the number of beach hazards while consolidating and simplifying information associated with beach hazards. There are many weather and water related hazards to life and property along beach/coastal areas and in the waters of the surf zone. The Beach Hazards Statement will provide additional, more targeted information to its customers and partners on hazards along beach/coastal areas and the waters of the surf zone. The NWS will also have the flexibility to provide information on many hazards in one statement. The NWS began testing the Beach Hazards Statement (BHS) on May 15, 2012, at select coastal Weather Forecast Offices (WFO) with the purpose of improving NWS services along beaches/coastal areas and in the surf zone. The Beach Hazards Statement (text format only) informs beach goers and local decision makers about a multitude of hazards including, but not limited to: dangerous currents (including rip currents and others) in the surf zone, unusually cold water temperatures, potential for lightning along the beach/shoreline, or unusual surf/wave conditions which do not meet advisory criteria. In coordination with other agencies, the product may also inform users of various types of environmental hazards (e.g. chemical spills, harmful algal blooms, high bacteria levels in the water, or potentially hazardous marine wildlife which may be impacting the area).

[Modification] Experimental Cold Advisoroy for Newborn Livestock National Digital Forecast Database GridsThe Cold Advisory for Newborn Livestock (CANL) System provides users with a decision support tool that could help reduce newborn livestock losses due to hazardous weather. The CANL was approved for operational implementation at the eight Western and Central Region WFOs that participated during the experimental period, effective March 19, 2013. As a result of customer satisfaction of the CANL products at the eight locations, the livestock industry expressed an interest in expanding the system to cover more areas across the country. Adding CANL grids in the National Digital Forecast Database (NDFD) can best address this expansion request The Cold Advisory for Newborn Livestock index forecast is now available as an element in NDFD experimentally. The CANL system uses the current NDFD forecast grids for temperature and wind (wind chill/sometimes called apparent temperature, humidity, sky conditions and Quantitative Precipitation Forecasts (QPF) to create a graphic that shows the potential for weather related impact to newborn livestock.

[Modification] Experimental Enhanced Data DisplayMulti-purpose web-based, cross-platform GIS system that provides our partners and customers with a single comprehensive web-based interface to access both forecasts and observations of any nature (public, fire, marine, aviation, hydrologic, climate, etc.). EDD puts this information in one place making it very easy to display and manipulate this data. EDD is hosted on the National Internet Dissemination System (NIDS) and was developed by the Weather Ready Nation Pilot Project in Charleston, WV.. EDD_PDD_07_9_13.pdf
[Modification] Experimental Enhanced Hazardous Weather Outlook (EHWO)The NWS core mission is to provide accurate and timely hazardous weather information for the protection of life and property. Although the textual Hazardous Weather Outlook (HWO) plays a vital role in supporting the NWS mission, effectively conveying hazardous weather information in a textual or narrative format can prove challenging to an increasingly diverse customer base. The EHWO is a decision support service that supports preparedness and response efforts prior to and during hazardous weather. In conjunction with the textual HWO, the clear and concise Internet-based EHWO graphics provides decision makers with convenient access to potential weather hazard information by graphically depicting the risk of multiple weather hazards out to seven days in the future. The Advanced Weather Interactive Processing System (AWIPS) Graphical Forecast Editor (GFE) produced EHWO packages multi-level color coded hazard graphics and text within a comprehensive web page suite. Further, weather hazards and thresholds are easily customized based on external customer needs for a particular office. Ultimately, workload is conserved through the use of existing local and national guidance GFE grids such as the Storm Prediction Center and the Hydrometeorological Prediction Centers, supporting a seamless office to office presentation.

[Modification] Experimental Expanded Impact Based WarningsThis is an expansion of the NWS Experimental Central Region Impact Based Warning demonstration in 2012 and 2013.Severe Thunderstorm Warning (SVR), Tornado Warning (TOR) and Severe Weather Statement (SVS) products will be stratified into categories distinguishing extreme cases from base convective warnings. Additional enhanced wording will be included to convey information about associated impacts, specific hazards expected, and recommended actions, both within the bullet statements and as part of the tag line codes.Based on feedback from the Central Region 2013 Experimental Impact Based Warnings, the 2014 demonstration will include some changes. The most significant change for the 2014 national experiment is that the impact statements for “CONSIDERABLE” and “CATASTROPHIC” serve as markers of confidence of tornado occurrence, with both reflecting an “elevated tier” of tornado damage and risk. The term CATASTROPHIC will only be used when a tornado is striking an actual community. Issuing enhanced convective warnings in 2014 will be the 38 Central Region Weather Forecast Offices (WFOs), 5 WFOs within NWS Southern Region (Norman, OK; Tulsa, OK; Jackson, MS; Lubbock, TX and San Angelo, TX); 1 WFO within NWS Eastern Region (Blacksburg, VA); and 2 WFOs within NWS Western Region (Great Falls, MT and Glasgow, MT).
