Figure 6-25 — From/To Example
Using the example in Figure 6-25, the first forecast line (KNSE 200909) begins FROM 0900Z
on the 20th and is good up TO 1400Z on the third line. (0900Z to 0900Z is also the 24 hour
forecast period.) The second forecast line (TEMPO0912) begins FROM 0900Z and is forecast to
occur up TO 1200Z. The third forecast line (FM1400) begins FROM 1400Z and is good up TO
1700Z, with some of these conditions changing by up TO 1700Z, the fourth line. The fourth
forecast line (BECMG1617) begins FROM 1600Z and is good up TO 2200Z. The fifth forecast
line (BECMG2022) begins FROM 2000Z and is forecast to occur up TO at least 0900Z, the end
of the forecast period. The sixth line (TEMPO2303) begins FROM 2300Z and is forecast to
occur up TO 0300Z.
Summary Of U.S. Civil/Military TAF Differences
Civilian weather stations are required to adhere to slightly different formats than military
stations, as has been discussed in the corresponding sections above. For reference, these
differences are summarized below. An example follows in Figure 6-26.
1. U.S. civil stations will use statute miles instead of meters.
2. U.S. civil stations include date time group of transmission prior to the forecast period (e.g.,
091720Z 081818).
3. When U.S. military stations amend, correct, or have a routine delayed forecast, a remark will
be appended to the last line of the forecast with the appropriate time (e.g., AMD2218).
4. U.S. civil stations may include probability of precipitation occurrence.
