METEOROLOGY FLIGHT PLANNING
In addition to the notes of Figure 1-11, the following are a few of the conventions used to report
present weather conditions in METAR/SPECI observations.
1. Present weather given in the body of the report occurs at the point of observation or within
five miles from the station. If the letters "VC" are used, the weather is in the vicinity of five to
ten miles. Any reported weather occurring beyond ten miles of the point of observation will be
included in the remarks portion of the METAR.
Intensity refers to the precipitation, not its descriptor (TS or SH).
TS may be coded by itself, or it may be coded with RA, SN, PL, GS, or GR.
INTENSITY DESCRIPTOR PRECIPITATION
Moderate BC Patches
SG Snow Grains
VA Volcanic Ash
VC In the
FC Funnel Cloud(s)
IC Ice Crystals
SH Shower (s)
PL Ice Pellets
GS Small Hail
1. Weather groups are constructed by considering columns one to five above in sequence, i.e.,
intensity, followed by description, followed by weather phenomena (e.g., heavy rain shower(s)
is coded as +SHRA).
2. No symbol denotes moderate intensity. No intensity is assigned to Hail (GR) or Icing (IC).
3. Tornadoes and waterspouts in contact with the surface are coded +FC.
