Airport Terminal Forecasts, TAF (Aviation Weather Center)

aviationweather/taf

The current Terminal Aerodrome Forecast (TAF) for up to 20 airports given as ICAO identifiers (for example KJFK or EGLL): the raw TAF text, when it was issued, its valid period, and each forecast period decoded with its start and end time, wind direction, speed and gusts in knots, visibility in statute miles, weather phenomena, cloud layers with base heights in feet and the type of change (FM, BECMG, TEMPO or a probability group). An airport that issues no TAF is absent, and no match at all gives an empty list. NWS Aviation Weather Center data, passed through unmodified and served by Eden Engine; not an official NWS or AWC product.
