Product Name Brief Description Operational Date
SPC Day 1-3 Categorical Convective Outlooks The Storm Prediction Center Day 1-3 Categorical Outlook include a defined areas of general non-severe thunderstorms, and 5 risk categories of severe convection (1 - Marginal, 2- Slight, 3-Enhanced, 4-Moderate, and 5-High). These outlooks previously included a defined area of general thunderstorms, and only three defined risk categories of severe convective weather (SLIGHT, MODERATE, and HIGH). The addition of “Marginal” and “Enhanced” categories will more closely compare to the SPC Day 1-3 Narrative and Probabilistic Convective Outlooks, and WFO products. 2014-10-22 
International Tsunami Products for the Pacific Basin The International graphical and statistical tsunami threat information product will be disseminated by the PTWC via email to a country’s designated Tsunami Warning Focal Point (TWFP) to support decision-making by that country’s tsunami warning organization. The email will also contain the accompanying international Tsunami Threat text messages (WEPA40). The tsunami warning organization may use the PTWC information as primary or supplemental guidance for determining their level of alert, and is responsible for issuing applicable alert levels such as warnings and watches to its own emergency management and stakeholder agencies, and/or the public. 2014-10-01 
Space Weather Prediction Website This completely redesigned site leverages the latest web technologies to reach the broadest possible audience. 2014-09-29 
NHC/TAFB Satellite Rainfall QPE and QPF Webpage This product 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 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. An experimental graphical version of these precipitation estimates is also provided as well as an experimental 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 2014-09-02 
NDFD Full Resolution The resolution has been increased in the National Digital Forecast Database. The NDFD spatial resolution will be available in experimental status at 2.5km resolution for all forecast times. The NDFD temporal resolution will be available in experimental status at one hour resolution for the first 36 hours from NDFD issuance time. These are the finest spatial and temporal resolutions at which Weather Forecast Offices in the Conterminous United States /CONUS/ provide forecasts. Forecasts from NWS offices and centers employing coarser resolutions will be mapped onto the finer resolution NDFD grid This change will affect files which contain data for the entire CONUS, but will not include Alaska, Hawaii, Guam, Puerto Rico and the Virgin Islands, or the 16 CONUS subsectors which will remain at their current operational resolutions 2014-08-19 
Probabilistic Tropical Cyclone Storm Surge and Tide Above Datum The Probabilistic Tropical Cyclone Storm Surge and Tide Above Datum consists of two suites of graphics. Probability of storm surge and tide above datum - series of graphics which show probabilities, in percent, of storm surge with tide exceeding 2 through 25 feet above North American Vertical Datum of 1988(NAVD88), at 1 foot intervals. Exceedance height of storm surge and tide above datum- series of graphics which show heights of storm surge with tide, in feet above NAVD88, which will be exceeded by a given percentage of storms. The suite of graphics range from 10 to 50 percent, at 10 percent intervals. 2014-07-08 
Probabilistic Hurricane Inundation Surge Height The Probabilistic Tropical Cyclone Inundation Guidance products has been renamed the Probabilistic Hurricane Inundation Surge Height product. a.The Probabilistic Hurricane Inundation Surge Height (PHISH)guidance products consist of two suites of probabilities for the Gulf of Mexico and Atlantic coastal areas: 1) Probabilities, in percent, of inundation exceeding 0 through 20 feet above ground level, at 1 foot intervals (e.g., the probabilities in percent, of inundation exceeding 0 feet, 1 foot, 2 feet, .. 20 feet). 2) Probabilities of inundation heights (above ground level) being exceeded. The suite of products range from 10 to 50 percent, at 10 percent intervals. Each of the probabilities mentioned above will be provided out to 78 hours as a cumulative probability, defined as the overall probability the event will occur at each grid cell from the start of the run until some specified time (e.g. 0-6 hours, 0-12, 0-18, etc.)and as an incremental probability, defined as the probability the event will occur sometime during the specified forecast period (e.g. 0 - 6 hours, 6-12, 12-18, etc.) at each grid cell. The products are based upon an ensemble of Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model runs using the National Hurricane Center (NHC) official advisory and accounts for track, size, and intensity errors based on historical errors. Plans are underway for tide to be incorporated into the suite of products during the 2013 hurricane season. Long term plans are to incorporate waves and freshwater (i.e. precipitation runoff and river inflow). 2014-07-08 
Spanish Tsunami Messsages The NWS/AR West Coast and Alaska Tsunami Warning Center (WCATWC) provides tsunami warning, advisory, watch, and information messages to its AOR which consists of Canada, Puerto Rico, Virgin Islands, and the ocean coasts of all states except Hawaii. Presently, the products are all issued in English. Three new products that mimic WCATWC tsunami products for the Atlantic (Puerto Rico, USVI, east coast, and Gulf of Mexico coast) that are composed in Spanish. The TSUATE product is the bulleted tsunami warning, advisory, and watch product. TIBATE is the bulleted tsunami information statement for earthquakes over magnitude 6. EQIAT1 is the bulleted tsunami information statement for earthquakes below magnitude 6. 2014-05-15 
NHC/TAFB Web Based Graphicast Daily graphical/alphanumeric depiction of significant weather features expected to affect the Tropical North Atlantic, Tropical Northeast Pacific and Southeast Pacific offshore waters and high seas area of responsibility of the Tropical Analysis and Forecast Branch. 2013-12-10 
Aviation Winter Weather Dashboard The Aviation Winter Weather Dashboard depicts the potential winter weather impact to the Core 30 (minus Honolulu) airports. Updated four times per day, the web display shows the potential impact to each airport through a matrix of color coded boxes that depict nominal (green), slight (yellow), moderate (orange), and high (red) impact through eighty-seven forecast hours. The impact information is calculated using the Short-Range Ensemble Forecast (SREF) numerical weather prediction system 2013-11-25 
Ice Accumulation Grids Effective Wednesday, October 15, 2014, at 1400 Coordinated Universal Time (UTC), the NDFD Ice Accumulation forecast grids will be extended in time from 48 hours to 72 hours. Six-Hour Ice Accumulation grids: The expected new ice accretion on all exposed surfaces (in hundredths of inches) during a 6 hour period. Issuance: An ice accumulation grid will be specified whenever at least a trace of ice accumulation is forecast for any hour during a valid period. Valid periods for the NDFD begin and end at 0600, 1200, 1800, and 0000 UTC. 2013-11-05 
Enhancement to National Spot Webpage: HYSPLIT Trajectories Request Function The Weather Forecast Office (WFO) NWS Spot webpages provide a nationally uniform portal for NWS customers to request, receive, and leave feedback for site specific spot forecasts. As of September 19, 2011, all WFO NWS Spot webpage hosted a new functionality for requesting HYSPLIT (Hybrid Single Particle Lagrangian Integrated rajectorymodel) trajectory runs from NOAA’s Air Resources Laboratory (ARL) on an experimental basis. On October 20, 2013 this functionality became operational. Trajectory elements will be available based on the North American Mesoscale Model (NAM) for the CONUS and on the Global Forecast System (GFS) for Alaska and Hawaii. The HYSPLIT trajectories Request Function will allow users to request HYSPLIT trajectory runs at 500, 1500, and 3000 meters for the latitude/longitude of the spot request. The trajectory runs will begin at the specified ignition time on the spot request. To request HYSPLIT trajectories with a spot request, the user must enter the phrase ..."hysplit to requester email address" in the remarks section of the spot request form. The HYSPLIT trajectory raw data, as well as gif and kml files, will be sent to the specified email address. 2013-10-29
