Listing of EXPERIMENTAL Products
Product Name Brief Description Submitter Date Entered
Prototype NWS on Instagram Provide the use of Instagram on a limited basis as a prototype through NWSI 10-102. Initial participation includes 2 WFOs per region and National Centers/National Water center. Melinda Bailey 2016-10-19
Prototype Storm Surge Watch Warning Graphic The prototype storm surge watch/warning graphic highlights areas along the Gulf and Atlantic coasts that have a significant risk of life-threatening storm surge inundation from a tropical cyclone, displaying areas that would qualify for inclusion under a storm surge watch or warning under development by the National Weather Service. The graphic represents the first step of a phased implementation toward an NWS storm surge watch/warning, but for 2015 does not represent an official NWS watch/warning. The NWS plans to debut an experimental storm surge watch/warning in 2016. After incorporating both user and partner input, the NWS expects to make the storm surge watch/warning fully operational in 2017 John F. Kuhn 2015-04-07
Prototype Texas Regional Rainfall Webpage The Texas Regional Rainfall webpage will display the most current quantitative precipitation estimates (QPE) produced by the Advanced Hydrologic Prediction Service (AHPS). Four maps containing QPE for durations of 24-hour, 48-hour, 72-hour, and weekly will be available each day for a region of Texas containing the County Warning Areas of the National Weather Service offices in Brownsville, Corpus Christi, Austin/San Antonio, and Houston/Galveston. There will be a built-in archive function on the webpage that will allow the user to quickly obtain QPE maps for past dates. Melinda Bailey 2015-12-15
Prototype Winter Storm Severity Index The prototype WSSI utilizes National Weather Service (NWS) gridded forecasts from the National Digital Forecast Database (NDFD) for winter weather elements and combines this data with non-meteorological or static information datasets (e.g., climatology, land-use, population) to create a graphical depiction of anticipated overall impacts to society due to winter weather.The experimental WSSI was evaluated internally at several Weather Forecast Offices (WFOs) last winter and produced excellent results. In most cases, the predicted WSSI impact was precisely the impact experienced. Feedback on the results was reported back to the originators at WFO Burlington and further improvement in the methodology is expected to yield even better results this upcoming winter – 15 selected WFOs in the Contiguous United States (CONUS) Regions will display the prototype on public facing web pages to gather feedback.

Sorm Surge Watches and Warnings The National Weather Service (NWS) is implementing new storm surge watches and warnings in association with Atlantic tropical cyclones affecting the continental U.S. beginning with the 2017 hurricane season. These additions to the NWS product suite will require changes to Tropical Cyclone Watch/Warning (TCV) and Hurricane Local Statement (HLS) products. All TCV products issued by the NWS during the 2017 season for tropical cyclones originating in the Atlantic basin affecting the continental U.S. would include Valid Time Event Code (VTEC) for storm surge watches and/or warnings when conditions warrant. In addition, the NWS is proposing to expand the VTEC available in TCV products issued by the National Hurricane Center (NHC) for Atlantic tropical cyclones affecting the continental U.S. to include all NWS-issued VTEC both along the coast and inland Because of the increased information included, it is possible that the NHC TCV product may not be sent until as much as 45 minutes after the NHC advisory package in some circumstances. No changes are expected for the release times of the TCV and HLS products issued by local Weather Forecast Offices (WFOs).Changes to the HLS products issued by WFOs would be limited to the “NEW INFORMATION” section of the product. The subsections for “CHANGES TO THE WATCHES AND WARNINGS” and “CURRENT WATCHES AND WARNINGS” would include storm surge watch warnings. Applicable changes will be made to the suite of tropicl cyclone products (text and graphics) to accomodate this implementation. Jessica Schauer 2016-06-30
