It ain't gonna happen of course...but never say never: Irma skirts the Florida west coast, cuts over the panhandle like Sherman to the sea, reforms as
a Cat. 3 over the Atlantic before merging with Category 3 Jose becoming...Irmosefina, Cat. 3+3=6.
Like I said, it ain't gonna happen, but never say never neither.
P.S. Only joking about the '6' part, there is no such thing of course
But given enough ocean heat in the Atlantic, combined with fortuitous wind shear coming out of the WNW, and it could happen. That's my point, if any:
high ocean temperatures equate to bigger, more numerous named storms. Storm systems that merge -- and it does happen from time to time -- form bigger
storms. That kind of anomalous situation is easier to imagine now than ever.
I am more concerned about Irma clearing Cuba and wondering West and gaining strength over the warm waters of the gulf. The gulf is very warm this time
of year. She could regain cat 4 or 5 then wonder north or west for landfall in an unprotected area from Houston to Mobile.
