As long as it is not a heavy rain, with lightning and thunder, deer move good when it is raining. Evenif it is raining pretty hard i'll try to get to my stand if I think that the weather will break, because I want to be there when it stops raining hard. They will usually move right after a hard rain. As far as scent goes, I'm not really sure. Some times I think scents linger longer in the damp air, so I always err on the side of caution and try to be as scent free as posible.
