4. AMD indicates an amended report. Reports can be amended due to
changing weather conditions or issuance/cancelation of a SIGMET.
COR in this field would indicate a corrected AIRMET. RTD indicates a

5. This line indicates that there is a second (2) update (UPDT) to this
AIRMET issued for turbulence (FOR TURB). More than one meteoro-
logical condition may be addressed as shown in the following:
FOR IFR AND MTN (mountain) OBSCN (obscuration)
FOR ICE AND FRZLVL (freezing level)
FOR STG (strong) SFC (surface) WINDS AND LLWS (low level
wind shear)

(Kansas) and MO (Missouri). Geographic areas are also covered such
as CSTL WTRS (coastal waters). Other geographic abbreviations are
used as well (see Appendix A).
8. The affected area is defined by lines FROM MCI (Kansas City) TO STL
(St. Louis) TO SGF (Springfield) TO ICT (Wichita) and back TO MCI.
Areas can be defined by lines between points which are airport or
navaid identifiers.
9. Moderate (MOD) turbulence (TURB) below (BLW) 10,000 feet
expected (EXPCD).
10. Conditions (CONDS) improving (IPVG) after (AFT) the 16th day (16) of
the month 0000 UTC.
If conditions end more than one hour prior to the indicated expiration time,
