If a tank carrying 95% nitric acid were to fail, it would seem most likely to do so from the inside out. I cannot imagine why getting rained or snowed upon would make a shred of difference.

I do not know the purpose of the shroud, so will refrain from guessing. But the possibilities that have been advanced thus far don't make a lot of chemical sense.
