Hail Mary

Last night there was a tremendous hailstorm over parts of West Flanders. What if someone in the midst of such a devastating tempest called upon the help of the Jesus' mother, praying "Hail Mary full of Grace etc."? Would she then know what to do? Would she make the storm abate or would she, as per what almost sounds like a request, make it hail even more? Of course, weather verbs are only used with it as the Subject and hardly ever occur in the imperative (as in Rain, goddammit, rain!), but higher forces such as the Sweet Mother of God have been implored to influence more than a bit of weather, so she might get confused.
