Anyone have an idea what will happen to this storm once it hits the Gulf Loop again? Will it intensify back up to a 5. Is that possible?
It's possible for it to become a 5 again. I can't address whether or not that's probable at this point.
It's never going to pass over the Loop Current again.
Yes it's possible, and I'd venture to say probable. It may very well stay a medium to strong CAT4, but one thing that's almost sure is that the wind field will expand.
