Experimental International Arrival and Departure GATE Forecasts These web-based International Departure Gate Forecast (IDGF) and International Arrival Fix (IAF) forecasts provide categorical convective guidance for specific locations in the National Airspace System (NAS) allowing for more accurate air traffic management. These forecasts will be a collaborative effort between the NOAA/NWS Center Weather Service Units (CWSU) located at the FAA Air Route Traffic Control Centers in Nashua NH (Boston), Ronkonkoma NY (New York) and Leesburg VA (Washington).The purpose of this experimental web page is to provide the Federal Aviation Administration (FAA) and the airlines with expanded weather planning information.This expanded information begins to address a gap in the NWS convective product suite and the Terminal Aerodrome Forecast (TAF). Specific forecast products are not available that forecast convective weather at aeronautical arrival and departure fixes (known as ‘gates’). Thunderstorm impact at or near these gates has a significant impact on the flow of aircraft through the NAS causing delays. This will allow critical partners and customers to make more informed decisions regarding the air traffic flow through the NAS. Scott Reynolds Approved for Operational
Experimental Mixed Case Letters in WFO Text Products Many NWS partners and users have identified the need for NWS text products to be provided in mixed case letters and to include an expanded punctuation and character set. Previously, national Public Information Statements (PNSs), including national Service Change Notices (SCNs) and national Technical Implementation Notices (TINs), were provided in mixed case letters with an expanded punctuation/character set for a risk reduction effort using non-operational products: ( This experimental PDD expands the risk reduction effort to a few operational, but non-critical, Weather Forecast Office (WFO) text products: the Area Forecast Discussion (AFD), the Regional Weather Summary (RWS) and local PNS’s (including local SCN’s and TIN’s) for four WFOs: Kansas City/Pleasant Hill, MO - EAX Louisville, KY -LMK Spokane, WA - OTX Tallahassee, FL - TAE Art Thomas Approved for Operational
Experimental National Spot Forecast Webpage NWS Spot is a website where NWS customers can request a spot forecast. The customer answers form questions on the website and then the website will compose an STQ text product that is sent to the AWIPS of the Forecast Office that is required to write the forecast. The forecast is generally composed on AWIPS as an FWS text product and transmitted like any other text product that is issued by the forecast office. The NWS Spot website databases these FWS products. Each FWS product includes a “.TAG” line, which helps the NWS Spot website associate each forecast request with a completed forecast. Spot forecasts are a critical mission of the National Weather Service. These forecasts are needed (for example) for those fighting wildfires, conducting prescribed burns, cleaning up HAZMAT incidents (like deepwater horizon), for search and rescue operations, and other critical operations, as needed.

Experimental NHC/TAFB Satellite Rainfall QPE and QPF WebPage (graphical portion) Experimental Comment period for the graphical portion of this webpage has been extended through November 2014. This experimental webpage provides event-driven satellite-based quantitative precipitation estimates (QPE) and model-derived quantitative precipitation forecasts (QPF) for tropical cyclones and tropical disturbances affecting areas within the National Hurricane Center and Central Pacific Hurricane Center areas of responsibility (AOR). The experimental product represents an improvement over the existing text-only satellite precipitation estimate product which is based on the Griffith-Woodley technique developed in the 1970s. The experimental product provides more robust satellite-based precipitation estimates from the Naval Research Laboratory (NRL) Blended and the Climate Prediction Center (CPC) QMORPH techniques and a time-matched forecast from the Global Forecast System (GFS) in tabular text and storm centered graphical formats. A graphical version of these precipitation estimates is also provided. In addition, the experimental product provides a graphical 24 hour QPF from the Princeton Geophysical Fluid Dynamics (GFDL), the NOAA Hurricane Weather Research and Forecast (HWRF), and the GFS models. The target audience for this product primarily includes the forecast centers in the Caribbean, Mexico, Central America, and the Eastern and Central North Pacific. . In addition, decision support service (DSS) entities would have access to targeted QPF guidance that may be of assistance for distributing and directing resources to areas impacted by heavy rainfall Hugh D.

Experimental NWS Emergency Response Tool The ERTool is a website designed for mobile devices that serves as a one-stop collection of the most popular NWS web pages.A frequent complaint from our partners is that the current NWS website is hard to navigate using a mobile device. In addition, finding weather data can be a cumbersome process, especially during high stress situations. This webpage will provide users the necessary weather information in no more than three clicks. Melinda Bailey Approved to Discontinue
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 Weeks 3-4 Temperature Outlook The National Weather Service, Climate Prediction Center delivers real-time products and information in order to monitor and predict climate variations and their potential associated impacts on timescales from weeks to about 1 year. The objective is to promote effective management of climate risk and a climate-resilient society. Currently, the Climate Prediction Center issues temperature outlooks for the Week-2 and 1-month outlook time periods. No current products exist for the intermediate timescale (i.e. Week 3-4) between these two forecast time horizons. The initial release of the experimental Week 3-4 Temperature Outlook will consist of two components. These are (1) a temperature outlook map targeting the combined Week 3-4 outlook, and (2) prognostic map discussion (PMD) text explaining the rationale for the forecast.

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: Dan Matusiewicz Approved for Operational
Proposal to operationally implement the Hurricane Local Watch/Warning Product (TCV) at WFO Honolulu The Hurricane Local Watch/Warning product (TCV) was operationally implemented at Weather Forecast Offices (WFOs) in the Atlantic hurricane basin during the 2015 Hurricane season to accompany changes made to the Hurricane Local Statement. Plans to implement for Western Region and the remainder of Pacific Region are to be determined at a later date. For the 2017 Hurricane Season, WFO Honolulu plans to begin issuing the TCV in the same format used by the WFOs covering the Atlantic Hurricane Basin. There will be no changes for Western Region or for other WFOs in the Pacific Region. Jessica Schauer 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.
