The general gist of this prophecy is that there will be at least one, if not several, super storms, and hurricanes, that hit the east coast, a few of which will happen completely out of season.  One hurricane is reported to be 500 miles wide at it's greatest size.  There's no timeframe on when these will hit, aside from one mention of an "out of season" storm, nor is there mention of where these will hit, save only that some of them will hit the east coast, and all will unfold in the Atlantic Ocean.
