Product Name Brief Description Operational Date
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. 2017-07-13 
Aviation Surface Forecast and Aviation Clouds Forecast Graphics The Aviation Surface Forecast and Aviation Cloud Forecast graphics are snapshot images derived from a subset of the aviation weather forecasts valid for the continental United States (CONUS) and coastal waters used within the Graphical Forecasts for Aviation interactive web-based display. The Aviation Surface Forecast graphics display surface visibility with overlays of surface wind and gusts, predominant precipitation type (i.e., rain, snow, mix, ice, or thunderstorm) coincident with any cloud, and predominant weather type (i.e., haze, fog, smoke, blowing dust/sand). Graphical Airmens Meteorological Information (AIRMETs) for Instrument Flight Rules (IFR) and Strong Surface Wind are overlaid. The Aviation Cloud Forecast graphics display cloud coverage fraction (few/scattered, broken, overcast) for clouds with bases below Flight Level 180 (FL180 - 18,000 feet above Mean Sea Level (MSL)). Text overlays indicate cloud coverage and height in feet above MSL at that particular location. Clouds above FL180 are indicated as Cirrus or CI above. Graphical AIRMETs for Mountain Obscuration and Icing are overlaid. Forecasted points may not represent conditions in proximity. 2017-07-10 
Storm Surge Watch Warning Graphic The storm surge watch/warning (SSWW) graphic highlights areas along the Gulf and Atlantic coasts that have a significant risk of life-threatening storm surge inundation from a tropical cyclone, subtropical cyclone, post-tropical cyclone,a potential tropical cyclone. he highlighted area designated the geographical areas at 2.5 km resolution under a gridded storm surge watch or warning.The graphic is intended to help users visualize areas most at risk from life-threatening surge, and serve as a call to action. All persons, regardless of whether or not they are in the highlighted areas shown by the graphic, should promptly follow evacuation orders and other instructions from local emergency management officials. 2017-06-01 
Storm 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. 2017-06-01 
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) can now 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. 2017-05-15 
Changes to Tropical Cyclone Forecast Graphics and GIS Files Effective on or about May 15, 2017, the appearance of the graphics accompanying tropical cyclone advisory packages issued by the National Hurricane Center (NHC) and Central Pacific Hurricane Center (CPHC) changeD. These changes are required for the NHC and CPHC to begin issuing forecasts and watches/warnings for potential tropical cyclones.three new Keyhole Markup Language (KML) files will be available and the wind speed probability Geographic Information System (GIS) files will be available at higher resolution. 2017-05-15 
Changes to the Graphical Tropical Weather Outlook 2017 Enhancements to the operational Graphical Tropical Weather Outlook 2017-05-15 
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. The Climate Prediction Center has added the Week 3-4 Temperature Outlook to its suite of products. The outlook consists 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. 2017-05-15 
Impact Based Warnings This is an expansion of the NWS Experimental Central Region Impact Based Warning demonstration in 2012 and 2013.Severe Thunderstorm Warning (SVR), Tornado Warning (TOR) and Severe Weather Statement (SVS) products will be stratified into categories distinguishing extreme cases from base convective warnings. Additional enhanced wording will be included to convey information about associated impacts, specific hazards expected, and recommended actions, both within the bullet statements and as part of the tag line codes.Based on feedback from the Central Region 2013 Experimental Impact Based Warnings, the 2014 demonstration will include some changes. The most significant change for the 2014 national experiment is that the impact statements for “CONSIDERABLE” and “CATASTROPHIC” serve as markers of confidence of tornado occurrence, with both reflecting an “elevated tier” of tornado damage and risk. The term CATASTROPHIC will only be used when a tornado is striking an actual community. Issuing enhanced convective warnings in 2014 will be the 38 Central Region Weather Forecast Offices (WFOs), 5 WFOs within NWS Southern Region (Norman, OK; Tulsa, OK; Jackson, MS; Lubbock, TX and San Angelo, TX); 1 WFO within NWS Eastern Region (Blacksburg, VA); and 2 WFOs within NWS Western Region (Great Falls, MT and Glasgow, MT). 2017-05-10 
Graphical Forecasts for Aviation In May 2015 the National Weather Service received a formal request from the Federal Aviation Administration (FAA) for the NWS to cease production of textual Area Forecasts (FAs), contingent upon the provision of equivalent meteorological information in support of aviation.The Graphical Forecasts for Aviation include observations and forecasts valid for the continental United States. Observational data and warnings are time synchronized and available by the hour for the current time and the prior six hours. Hourly model data and forecasts, including National Digital Forecast Data (NDFD), are available to 15 hours in the future. Wind, icing and turbulence forecasts are available in 3000 ft. increments from the surface up to 18000 ft. MSL, and in 6000 ft. increments from 18,000 MSL to FL420 (42,000 ft. MSL). Turbulence forecasts are also broken into LO (below 18,000 MSL) and HI (at or above 18,000 MSL) graphics. A maximum icing graphic and maximum wind velocity graphic (regardless of altitude) are also available.Multiple fields of interest are combined in categories that the user is able to select from the top level Weather menu. The data for each category is determined by the time period, observations (current time and the prior six hours) and forecasts (valid up to 15 hours in the future). Additional information is available in text format when mouse-clicking on the map or using the hover function. The “Configure” menu enables the user to customize the satellite and radar displays in addition to choosing parameters for the observations and aviation advisories displayed. Imagery, observations, and forecast graphics are overlaid on high-resolution basemaps from ESRI, including colored relief, satellite and street views. Overlays include navigational aids, airports, and heliports for the entire United States. More detail is revealed as you zoom in and individual layers can be turned on or off independently. 2017-04-13 
Hurricane Local Watch/Warning Product (TCV) Updated 2017 to add 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. 2017-01-20 
Aviation Weather Center Impacts Terminal Aerodrome Forecast (TAF) Board The AWC Impacts TAF board is a time series display of weather conditions at select airports across the United States. Each box (hourly forecasts from TAF) is color-coded based on the level of the hazard. White represents no impact, yellow slight impact, orange medium impact, and red high impact. The letters in the box represent the cause of the hazard. They are as follows: -CIG – Ceiling (hundreds of feet, Above Ground Level [AGL]) -VIS – Visibility (statute miles) -WX – Weather (see legend) -WSpd – Wind speed (knots) -WGust – Wind gusts (knots) 2016-11-28
