As those of you who were at NACIS know, I've been involved in making (base) maps for a number of weather websites. The latest one that I finished is this one:

As of today it's live on http://meteox.com
The terrain data is an adapted version of Tom Patterson's Natural Earth (Hypsometric with shaded relief), vector data is all Natural Earth Vector. I just produce the base map, the rainfall data is layered on top of that in the web frontend. One of the major concerns is of course that there should be enough visual contrast between the base map and the rainfall data, this does limit my color choices quite a bit. In this particular case I had to stick close to the original version of the map as well, since that's what users are familiar with.
I'm pretty pleased with how this came out, and so is the client. However, I'm curious to hear what you all think about it, not in the least place because I just heard they want a bigger version (2250 x 2250 instead of 550 x 550 pixels) as well. That one is supposed to have roads in it too, which might be tricky in terms of color.
