New to SH3

Greeting everyone, I am trying to follow the advice given in an earylier thread for a first time install of the sim. I need to find a file named "SH3Weather". Can some one let me know where to find this file? If it is in the downloads on this site, I am just plain overlooking it. I purchased this sim after lurking on this forum for a while and found that everyone seemed to be really involved and enjoying this submarine sim. Just have to give it a try.

Thanks for the help. I'm sure I will need more.
Glad to be aboard.

Jim
