JPATS AVIATION WEATHER BOOKLET
If RVR is varying, the coding will be the same as above, except the two reportable values will be
separated by a “V.” If RVR is less than its lowest reportable value, the 4-digit value will be
preceded with an “M” (for Minus), and if greater than the highest reportable value, it is preceded
with a “P” (for Plus).
Examples:
R33/1800FT — Runway 33 visual range 1800 feet.
R17R/3500FT — Runway 17 Right visual range 3500 feet.
R09/1000V4000FT — Runway 09 visual range 1000 feet variable to 4,000 feet.
R28L/P6000FT — Runway 28 Left visual range greater than 6000 feet.
R02/M0800FT — Runway 02 visual range less than 800 feet.
NOTE: Runway visual range is not reported from USN/USMC stations. It will, however, be
disseminated locally to arriving and departing aircraft.
Group 7: Present Weather
Present weather includes precipitation, well-developed dust or sand swirls, squalls, tornadic
activity, sandstorms, and duststorms. It may be evaluated instrumentally, manually, or through a
combination of methods. The codes used for present weather as seen below in Figure 6-9 and
Table 6-2 are used throughout meteorology.

Figure 6-9 — Present Weather in METAR
In addition to the notes of Table 6-2, the following are a few of the conventions used to report
present weather conditions in METAR/SPECI observations.
A. Present weather given in the body of the report occurs at the point of observation or within 5
miles from the station. If the letters “VC” are used, the weather is in the vicinity of 5-10 miles.
Any reported weather occurring beyond 10 miles of the point of observation will be included in
the remarks portion of the METAR.
B. Intensity refers to the precipitation, not its descriptor (TS or SH).
C. TS may be coded by itself, or it may be coded with RA, SN, PL, GS, or GR.
