LGT - Light - Rate of accumulation may be a problem if flight
is prolonged for longer than 1 hour without deicing/anti-icing
equipment. Deicing/anti-icing removes and/or prevents accu-
mulation.
MOD - Moderate - The rate of accumulation is such that even
short encounters become potentially hazardous. Use of
deicing/anti-icing equipment or diversion is necessary.
SEV - Severe - Flight diversion is necessary. Deicing/anti-
icing equipment is not effective.
/RM: Remarks (for reporting elements not included or to clarify pre-
viously reported items). Remarks can include anything. The
example translates to “moderate (MDT) mixed (MXD) icing during
climb (DURGC) from Roanoke, VA (KROA) northwestbound
(NWBND) between Flight Level 080 and 100 (FL080100) at
1750Z”.
