PRODUCT DESCRIPTION
SIGMET Text/graphical report − Potentially hazardous en
route phenomena such as thunderstorms and hail,
turbulence, icing, sand and dust storms, tropical cy-
clones, and volcanic ash in an area affecting 3,000
square miles or an area deemed to have a signicant
effect on safety of aircraft operations.
SIGMET,
Convective
Text/graphical report - hazardous thunderstorms
and related phenomena across Continental US.
Convective SIGMETs issued for thunderstorms
and related phenomena do not include with thun-
derstorms such as turbulence, icing, low level wind
shear and IFR conditions
TAF Text report - Terminal Aerodrome Forecast is a format
for reporting aviation weather forecast information.
Generally a TAF is a 9- or 12-hour forecast, though
some TAFs can cover an 18- or 24-hour period. TAFs
complement and use similar encoding to METAR
reports. They are produced by a human forecaster
based on the ground. For this reason there are fewer
TAF locations than there are METARs. TAFs can be
more accurate than Numerical Weather Forecasts,
since they take into account local, smallscale, geo-
graphic effects.
Winds and
Tempera-
tures Aloft
Graphical report - Winds and Temperature Aloft Fore-
cast is forecast for specic atmospheric conditions in
terms of wind and temperature in a specic altitude
measured mostly in feet (ft) above mean sea level
(MSL). The forecast is specically used for aviation
purposes.
