Product Name Brief Description Submitter Date Entered
Experimental Rayleigh Distribution in the NWS Coastal Waters Forecast Product Comment period extended to add more SR offices. WFOs Miami, San Juan, Houston, Brownsville, Jacksonville, Corpus Christi and Houston. This is an enhancement to the CWF product at WFO Miami (MFL) with the inclusion of additional wave height fields by implementing the theoretical Rayleigh Distribution. The inclusion of the average height of the highest 10%of waves observed at sea into the CWF product will provide a more descriptive and accurate assessment of the wave field expected for any particular time across a given marine zone.

Experimental Revised Wave Terminology in the Coastal Waters Forecast Provide enhanced descriptions of the wave environment in the coastal waters. This will eliminate the terms “wind wave” and “swell” from the CWF and replace them with more descriptive wave systems. the enhanced wave terminology will introduce an overall sea state to every forecast period and provide a wave period for each significant wave system. Each forecast period will contain at minimum the overall sea height and a dominant period. At maximum given forecast periods will contain an overall sea height and its component wave systems and associated wave periods. At most, four wave systems could be listed. The old way of creating the CWF forces forecasters to arbitrarily break a combined sea state into swell and wind wave components using nomograms from the middle of the last century. Moving toward enhanced wave terminology allows the forecaster to detach from rules of the last century and leverage off of modern technology and establish a framework for utilization of future wave modeling advances.

Experimental Service National Weather Service Provision of Supplemental Public Safety Information before, during and after High Impact Events A number of government agencies (federal, state and local) produce supplemental public safety information that is useful to the general public before, during and after high impact events. Recently, after two such high impact events, the National Weather Service (NWS) was able to share supplemental public safety information via the National Oceanic and Atmospheric Administration (NOAA) Weather Radio (NWR) and as messages in text format via the Public Information Statement (PNS) or Special Weather Statement (SPS) as described in NWSI 10-501 and NSWI 10-517. This SDD describes a service that will provide an established method of dissemination of this important information, without incurring the cost that would come with setting up a dissemination architecture system Michelle D.

Experimental Severe Weather Impact Graphics This product is a graphical depiction of each short-fuse warning product issued by the NWS Weather Forecast Office (WFO), CONUS only, with the inclusion of impact information to supplement the graphics. "Short-fuse warnings" include Tornado, Severe Thunderstorm, Flash Flood and Extreme Wind Warnings. Brian Walawender 2014-06-03
Experimental Short Range River Forecast Uncertainty (AHPS) A graphical hydrograph depiction of short-range river forecast uncertainty. The product provides probabilistic bounds for the river forecast in the context of high and low water thresholds used in AHPS. Ernie Wells 2015-02-25
Experimental Situation Report Hazardous Weather Outlooks modified to include graphics, links and other relevant information. Name changed from Experimental HWO Briefing. Derek Deroche 2014-01-08
Experimental SPC Probabilistic Day 3-8 Fire Weather Outlooks The SPC Probabilistic Day 3-8 Fire Weather Outlooks provide a daily probabilistic forecast of critical fire weather conditions for dry thunderstorms and/or strong winds combined with low relative humidity for the continental U.S. John Ferree 2011-04-12
Experimental Tampa Bay Marine Channel Forecast Point forecast for 13 locations along the Tampa Bay channel designed to aid local mariners including emergency managers, United States Coast Guard, researchers (NOAA, universities, Florida Fish and Wildlife), Tampa Bay Harbor Pilots, towing or tug boat operators, recreational boaters, and any customer or partner with interest in the respective environmental data for Tampa Bay. A static Google Earth map displays the shipping channel in Tampa Bay along with 13 forecast points. Digital and high resolution model forecast data are used to produce the forecast for all points. Users may click on any point to view the latest information. Melinda Bailey 2012-12-05
Experimental User Defined Area Forecast Web Application Enhanced Service, allowing user to select area for which forecast information is derived from the point-and-click data base. The User Defined Area Forecast (UDAF) is an Internet-accessible application which allows direct interaction with the full resolution (2.5km horizontal grid spacing) NWS netCDF forecast data base to obtain forecast information within a geographic area specified by the user. The interface allows an individual to define geographical boundaries in both area and elevation, and submit those values to retrieve a forecast directly from the digital forecast data base populated by NWS meteorologists at local weather forecast offices (WFOs) responsible for that user-defined polygon domain. Output is presented in the same format as the point-and-click forecast, but based on an average value of the area specified. Additionally, a table with maximum and minimum values is created, along with statistics about the size and elevation range of the selected area. The area itself is displayed graphically to ensure the area from which the data is derived matches the user’s identified zone of interest. A future upgrade will incorporate affected population within the table, by querying the US census data base. Kim Runk 2013-03-29
Experimental Water Information Interface Webpage Effective on or about Tuesday, June 14th, 2016, the National Centers for Environmental Prediction (NCEP) will begin operationally running version 1.0 of the National Water Model (NWM). The NWM is an hourly uncoupled hydrologic analysis and forecast system that will provide streamflow for 2.7 million river reaches and other hydrologic information on 1km and 250m grids. The NWM provides the NWS with a multi-scale, parallelized, process-based water cycle modeling capability. Upon initial implementation, the NWM system will provide multiple country-wide hydrologic analysis products and forecast output across a range of forecast lead times. These will be combined with other data from NOAA to provide the Nation with comprehensive information on a range of water-related concerns such as snowpack, soil moisture, and potential areas of flooding.Version 1.0 of the NWM will provide a capable and solid foundation that will support year-over-year growth in operational hydrologic forecasting capability. Goals for this initial implementation include: 1) Provide forecast streamflow guidance for underserved locations 2) Produce spatially continuous national estimates of hydrologic states (soil moisture, snow pack, etc.) 3) Seamlessly interface real-time hydrologic products into an advanced geospatial intelligence framework 4) Provide a modeling architecture that permits rapid infusion of new data, science and technology Dan Roman 2016-03-16
Experimental Weather, Water, and Climate Information Podcasts Podcasts are produced through the use of Really Simple Syndication (RSS) feeds and industry-standard mp3 files created by the NOAA Weather Radio All Hazards (NWR) broadcast management system that can be distributed over the Internet using syndication feeds, for playback on mobile devices and personal computers, thus making NWS data and products available in Internet-accessible, vendor-neutral form. The Podcasts are not a replacement for NWR and do not offer the warning capability of NWR Specific Area Message Encoding or Warning Alarm Tone, but rather allow the user to download products for playback at a later time on their computer or portable mp3 player.

Experimental Weeks 3-4 Precipitation Outlook The NWS Climate Prediction Center (CPC) issues temperature and precipitation outlooks for the Week-2 and 1-month outlook periods. To close the gap- intermediate time scale (i.e., Weeks 3-4) between the 2 week and 1 month forecast time horizons, the CPC developed and solicited comments on the Experimental Weeks 3-4 Temperature and Precipitation outlooks. The Temperature outlook has been approved for operational implementation. The precipitation outlook needs additional testing and the experimental comment period has been extended for another year. The objective of the product is to highlight regions where above or below average 2-week mean total precipitation are favored as well as provide advance notice of potential precipitation pattern changes to further assist decision makers in weather and climate sensitive activities in their decisions.
