Alaska Graphic Area Forecast The Alaska Graphic Area Forecast (GFA) is a graphical representation of forecasts contained in the text Area Forecasts (FA) for Alaska. The GFA is comprised of four separate graphics produced using NMAP software at the Alaska Aviation Weather Unit (AAWU). 2003-04-25 
Aviation Area Forecast (FA) Aviation Area Forecasts (FAs) describe in abbreviated language the development and occurrence or expected occurrence in time and space of specified en-route weather phenomena below Flight Level (FL) 45,000 ft (450). The FA is a forecast of visual meteorological conditions(VMC), clouds, and general weather conditions over an area the size of several states. In Alaska, the FA also includes forecasts of Instrument Flight Rule (IFR) conditions as well as other AIRMET and SIGMET information on thunderstorms, wind, icing and turbulence. Over CONUS and Hawaii, the FA must be used in conjunction with the in-flight aviation weather advisories to understand the complete weather picture. Together, they are used to determine forecast en-route weather and to interpolate conditions at airports for which no Terminal Area Forecasts (TAFs) are issued. 2003-04-25 
Significant Meteorological Information (SIGMET) SIGMETs are concise, brief descriptions of the development and occurrence or expected occurrence in time and space of specified en-route weather phenomena which may affect the safety of all aircraft operations. 2003-04-25 
Airman's Meteorological Advisories (AIRMET) AIRMETs are concise descriptions in abbreviated language of the development and occurrence or expected occurrence in time and space of specified en-route weather phenomena issued by the National Weather Services Aviation Weather Center, Alaskan Aviation Weather Unit, and Weather Forecast Office Honolulu. AIRMET phenomena can affect the safety of aircraft operations. Bulletins contain details of potentially hazardous conditions over the continental United States, Alaska, Hawaii, and adjacent waters. An AIRMET will be issued when any of the following weather phenomena occur and affect an area of at least 3,000 square miles: Moderate icing, Moderate turbulence, Sustained surface wind of 30 knots or more, Ceilings less than 1,000 feet and/or visibility less than miles affecting over 50 percent of an area at any one time or, Extensive mountain obscuration (may be less than 3000 square miles for Pacific Ocean islands). 2003-04-22 
Center Weather Advisory (CWA) The National Weather Service's (NWS) Center Weather Advisory (CWA) is an aviation warning for conditions meeting or approaching national in-flight advisory criteria ( ie AIRMET, SIGMET, or SIGMET for convection) as described in NWSI 10-811. 2003-04-22 
Meteorological Impact Statement (MIS) The National Weather Service's (NWS) Meteorological Impact Statement (MIS) is a unscheduled flow control and flight operations planning forecast.  The MIS is valid 2-12 hours after issuance time and details weather conditions expected to adversely impact 2003-04-22 
Winds and Temperatures Aloft Forecast The Winds and Temperatures Aloft Forecast (FDHW) is an alphanumeric product providing a coded forecast for winds and temperatures aloft for Lihue, Honolulu, Kahului and Hilo within the National Weather Service's Pacific Region's Weather Forecast Office ( 2003-04-22 
Graphical Turbulence Guidance The Graphical Turbulence Guidance (GTG) is an automatically generated turbulence product that predicts the location and intensity of turbulence over the continental United States (CONUS). 2003-04-18 
Aviation Weather Warning (AWW) The AWW is a National Weather Service (NWS) operational warning for weather with the potential to impact ground operations at some airports. Specific warning criteria are decided by local airport management and the supporting Weather Forecast Office and 2003-04-17 
Convective SIGMET Convective Significant Meteorological Advisories (WST) is a text product describing the occurrence or expected occurrence of thunderstorms and related phenomena over the conterminous United States and adjacent coastal waters within 2 hours of issuance tim 2003-04-17 
Terminal Aerodrome Forecast (TAF) The TAF is an operational forecast consisting of the expected meteorological conditions significant to a given airport or terminal. TAFs always include a forecast of surface wind speed and direction, visibility, and clouds. 2003-04-17
