12 Beginning and Encode beginning and ending of thunderstorm(s) in format, X X X

Ending of TSB(hh)mmE(hh)mm, where TS indicates thunderstorm, B
denotes the beginning, E denotes the ending, and (hh)mm is the
Thunderstorms
time of occurrence (only the minutes are required if the hour
(See Note 1) can be inferred from the report time). There are no spaces
between the elements. For example, if a thunderstorm began at
0159 and ended at 0230, the remark would be encoded
"TSB0159E30." FBWOSs automatically provide a remark both

when the thunderstorm begins and ends (e.g., TSB1635
indicates a thunderstorm began at 1635Z).
13 Thunderstorm Encode thunderstorm(s) in format, TS_LOC_(MOV_DIR), O
Location where TS identifies the thunderstorm activity, LOC is the
location (distance if known) of the thunderstorm(s) from the
installation, and MOV_DIR is the movement with direction, if
known. For example, a thunderstorm 8SM southeast of the
installation and moving toward the northeast would be encoded

"TS 8SE MOV NE."
14 Hailstone Size Encode hailstone size, GR_[size]_[Plain Language], where X(*) X(*) X(*)
GR is the remark identifier and [size] is the diameter of the
largest hailstone. The hailstone size is encoded in ¼-inch
increments. For example, "GR 1 3/4" would indicate that the

largest hailstones were 1¾ inches in diameter. If hail smaller
than ¼ inch is observed shall be coded as less than ¼ inch (i.e.,
“GR LESS THAN 1/4”).
15 Snow Pellet Encode snow pellet intensity in the format GS_[intensity], X X X
where GS is the remark identifier and [intensity] is the observed
intensity. The snow pellet intensity shall be coded as LGT,
MOD, or HVY incidating light, moderate, or heavy intensity,

respectively.
