so who get’s to make up these names? Rivers all wind their own way to the sea.  Vapor, what Atmos means in Latin, rises it’s way to the sky, then (hopefully) comes down as rain, to wind up in a river again, etc. etc.  should be “vapor stream”, or “moisture channel”, “river” is for ground water mmkay?  but even noaa is using it now.  oh well.  still pretty stuff (from NRL MRY, test of gify download), lined up pointing right at the bay, check ur galoshes and rain jackets, will be too windy for umbrellas.
