Okay put 2 positions and each corner of where the snow is , then click copy and replace and you are gonna wanna find and click snow then (dont click fill yet) click replace (right ontop of fill) then click click air(0) and then press *fill* then you are all set and done.
That's just temporary. If you're building a survival map and you don't want people to have snow, telling them to install SPC and whenever weather comes turn it off isn't the best of solutions.
By the way, if you're using SPC you don't need the /.
Anyway, you can use WorldEdit to //thaw areas which will turn them into rain areas instead of snow areas. If you just remove the snow then next time it will just snow again, whereas the //thaw command changes the weather in that area to rain instead of snow. :biggrin.gif:
