TAF Brazil decoding

[2009PP]

Good day, I have spent quite sometime to search for an answer, but I wasnt't lucky.

May be you can help me with an answer and or a link:

the TAF of Brazilian Airports contains a group of 3 letters after the "RMK",

i.e.: PGF= or PGH or PGS or PCW

Any idea? I have found something like pressure gradient may be involved...

Thanks, Tom

Thanks!

Strange that I didnt find it with the search function

If this is true, they dont have many people working there- and a lot of them have the same 2 letters: "PG"....

Anyway, Thanks!
