WX

WX is the telegraph abbreviation for weather. It was also used for the same purpose in Morse code. Its use still continues as written 'shorthand' especially within the weather fraternity, among the aviation and maritime communities, by amateur radio operators, and in the television and radio broadcast field. The NOAA Weather Radio channels are numbered WX01 through WX10.

It is also the IATA airline designator code for CityJet.
