Pure speculation, but I doubt much will be left of this thing once the "feature" makes it to the Caribbean side. It already looks to be elongating even more - almost into a trough-like presentation. This thanks to vertical shear and disruption from the high terrain. Storms that usually survive the best upon crossing high terrain are ones that are very well stacked vertically, such as storms that have made landfall under low shear and symmetrical outflow conditions. What then happens is that the mid-level circulation remains vigorous (as it's high enough to be influenced less by terrain); after emergence back over water, the circulation then quickly builds back down to the surface.
With Adrian, we have a situation where the storm was already tilted with height due to shear. Thus, the mid-level circulation will shear off on its merry way as the low-level circulation gets hung up over the mountains. By the time this low pressure area translates across the mountains to the other side (if at all), there's no "support from above" to whip it back into shape and keep it spinning.
The next 24 hours will be fascinating, because it's rare to get a sheared system, yet with potency at landfall, attempt to cross a high mountain range.

It certainly doesn't look as strong as it did a few hours ago.
