Probably no harm especially if it was some distance from your apiary. You are going to be cold and wet for several days so any flying moths will seek dark shelter, like under the top cover on top of the inner cover. You might want to take a quick look there. If the hives are strong the moths won't be a problem, weak hives with extra space is another story, same with SHB. They are both scavengers and pose no threat to strong colonies.
