It will keep most of the elements out but it is not completly water proof. I have never seen water inside of mine but it looks like it could get in there. With a different gasket it might work better. But that would be the hard part. Finding a suitable sealer. Kevan tried numerous materials and his goal was to have it as weather tight as possible.
Hopefully Kevan will chime in on this. He did a lot of research on the seal.
