actually, what you had there all along is a double eye-wall structure... the inner one spent the last 24 hours, bodily inland and therefore is finally subcumb and is in the process of probably decaying altogether... Meanwhile, the outer eye-wall only was half situated on land, the other half was out over the warm fuel source and was therefore able to sustain much of the landfall process - being also that in all, this means that process was imcomplete...

from here, it is uncertain whether this will get stronger when it moves back over the Gulf but that definitely seems more plausible than not... the loop current still holds substantial heat content and this is modeled to pass straight over the top.. also, since wilma will be accelerating, there is a chance that her storm relative shear will be less than the environmental shear... so, a few factors suggest that this outer eyewall will be contracting given time; not a certainty.
