[Modification] Dust Storm Warning/ Dust Advisory Dust Storms are unique, extremely localized extreme weather events that can result in high impact to the public and commerce. Currently, hazard messages for these events are issued via generic Special Weather Statements (SPS) that are not enabled by Valid Time Event Code (VTEC). There is a long-standing need for a capability for the National Weather Service (NWS to be able to effectively disseminate this information to our partners who depend upon VTEC to recognize and parse our warning products for their customers.) In addition, the capability to define localized areas of threat (e.g., as is available for severe thunderstorms, tornadoes and flash floods through the use of NWS WarnGen software) would improve communication to the public via Wireless Emergency Alerts (WEA). The Dust Storm Warning/Dust Advisory will be short-fused and polygon-based enabling improved dissemination technique for maximum user distribution and effective Decision Support Services and will provide the critical, life-saving information for these short-term, highly localized, extreme hazardous events to our partners in the form that will allow them to recognize and parse the products and make them available to their customers. NWS will request dissemination via the Emergency Alert System (EAS) using event code DSW. NWS will broadcast short-duration Dust Storm Warnings over NOAA Weather Radio All Hazards (NWR) and disseminate using Specific Area Message Encoding (SAME) and 1050 Hz warning alarm tones. NWS will also display the warning polygon on NWS radar depictions. PDD for DSW.pdf
[Modification] Enhanced Impact Based Decision Support ServicesThis Service Description Document describes NWS’s impact-based decision support services (IDSS) provided for the protection of life and property to officials that serve within Emergency Support Functions as outlined in the Department of Homeland Security’. idss_sdd_emc_Version_2 (3).pdf
[Modification] Enhanced Product Experimental RFW Bullet Format (local enhancement to national product)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.pdf
[Modification] Enhancement to the Operational Twitter SDDUpdate Service Description Document for Twitter to indicate that NWS may provide tweets of short fused watches/warnings/advisories. Current description of our service indicates that NWS will only provide tweets with long fused alerts. Also need to indicate that NWS may provide content-specific feeds in addition to office-oriented feeds. Content specific feeds better meet the needs of our national partners who aren’t focused on the area of only one particular office. twitter_sdd_update.pdf

[Modification] Experimental Arrival of Tropical Storm Force Winds GraphicThe anticipated arrival of sustained tropical-storm-force winds from a tropical cyclone is a critical threshold for coastal communities. For example, emergency managers use this information to determine when to begin and complete coastal evacuations, while the public needs to know when to prepare their homes or businesses and get supplies. Once sustained tropical-storm-force winds begin, such preparations usually become too dangerous or difficult. Historically, many decision makers have inferred the arrival of sustained tropical-storm-force winds from NHC products deterministically, without accounting for tropical cyclone track or size uncertainty. The risk in not factoring in these uncertainties is that communities may have less time to prepare if a tropical cyclone speeds up or increases in size beyond NHC initial forecasts. To better meet users needs, NHC has developed a set of prototype graphics that depict when sustained tropical-storm-force winds from an approaching tropical cyclone could arrive at individual locations. The prototype maps were developed and tested using social science techniques, including one-on-one telephone interviews, focus groups, and surveys with emergency managers, broadcast meteorologists, and NWS meteorologists to gather opinions on the idea, content, and design of the products.

[Modification] Experimental Beach Forecast Web PageThe Beach Forecast Webpage is a website designed for beach goers to easily see hazards and forecasts along various beaches. This webpage is being developed for SR coastal Forecast Offices, and if feedback is favorable will most likely be expanded to other regions as well. This webpage offers rip current risks graphically, descriptions, and actions to take. The webpage also offers UV Index information. The map is clickable, and from there you get a weather forecast and also rip current risk and UV index information as well. The webpage offers links to the forecasts for the beach areas, water temperature when available, and other information such as links to lightning safety information and local radars.

[Modification] Experimental Collaborative Aviation Weather Statement (CAWS)The Collaborative Aviation Weather Statement (CAWS) is a product (weather service) collaborated by National Weather Service (NWS) meteorologists, airline meteorologists, and other airline and Federal Aviation Administration (FAA) personnel. The CAWS focuses on specific, convective forecasts impacting the Core 29 airports and high traffic en-route corridors. The focus is event-driven, supporting the ability to more effectively initiate, adjust, or terminate planned or active Traffic Management Initiatives (TMI) to balance traffic demand in the constraint locations CAWS_PDD.pdf
[Modification] Experimental Day 4-7 Winter Weather Outlook The Day 4-7 Winter Weather Outlook is a graphical probabilistic forecast depicting the probability of winter precipitation (snow/sleet) exceeding 0.25 inches (~6 mm) water equivalent over a 24-hour period. The product is comprised of 4 graphics showing the forecast for Day 4, Day 5, Day 6, and Day 7.

[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 Graphical 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.
