I know that weather is not climate but this is too good to pass…(thanks to D88 for pointing this out)
The extraordinary 2008 snowstorms in China may have to be remembered also for having reached so far south.
Look at the NOAA’s “current snow” picture for Asia and Europe as it is at the time of writing:
The southernmost tongue of white stuff is ominously pointing towards Hong Kong itself. Actually, it can be estimated to have reached the city of Guiyang (26.32N, 106.40E: around 200 miles north of the Tropic of Cancer).
In fact, the current weather forecast for Guiyang is light snow, between 1C and -6C between January 31 and February 2 at least.
Climate-wise, placed at an elevation of 1,100 meters, Guiyang is know for the occasional flurry, although the average January temperature is 10C.
