TAF
(Terminal Aerodrome Forecast)
is a weather forecast at an airport or military base for a specific period
(usually 24 hours).
AMD
(Amended Aerodrome Forecast)
is issued because the previous version is no longer representative of the current or expected weather. The amended TAF supersedes the previous TAF.Always refer to the date/time group at the end of the TAF to determine the most current forecast.
COR
(Corrected Aerodrome Forecast)
is a TAF that has been corrected. When a corrected TAF is issued, disregard previous TAFs.
TEMPO 1316 1 1/2SM BR
“Temporary condition between 1300Z and 1600Z of 1 1/2 statute mile visibility in mist.” Only the temporary changing conditions are included in TEMPO groups.
FM 1600 16010KT P6SM NSW SKC
FM means “from” and indicates a rapid weather change where all data groups in the previous line are superseded. In this example, FM 1600 reads, “From 1600Z … ”
BECMG 2224 20013G20KT 4SM SHRA OVC020
“becoming” or a “gradual change” in meteorological conditions and becomes the predominant group by the end time listed. In this example, BECMG 2224 reads “Becoming from 2200Z to 2400Z.”
PROB40 0006 2SM TSRA OVC008CB
(civilian use only) represents a 40% probability or chance of conditions occurring along with associated weather conditions (wind, visibility, sky conditions).
CAVOK
Overseas locations may use the contraction “CAVOK” (ceiling and visibility OK). CAVOK is used when there is no significant weather, the visibility is 10 km or greater, and the ceilings are greater than 5,000 ft.
WS010/18040KT
“forecast wind shear at 1,000 feet above the station; wind at 1,000 feet is from 180 degrees (true) at 40 knots.”
METAR
Meteorological Aerodrome Report
SPECI
(Special Report) refers to an unscheduled observation that met a predefined criteria (such as a change from VFR to IFR). The new weather conditions are encoded in a standard METAR report.
R32L/0300
“runway visual range for 32 Left is 300 meters.”
